Description

Battery and electronic device

[ technical field ] A method for producing a semiconductor device

The present application relates to the field of battery technologies, and in particular, to a battery and an electronic device.

[ background of the invention ]

An electrochemical device is a device that converts external energy into electric energy and stores the electric energy in the device to supply power to external devices (e.g., portable electronic devices) at a desired time. Generally, an electrochemical device includes a case, an electrode assembly housed in the case, a first tab, and a second tab.

If the current is too high due to a short circuit or the like during the power supply of the electronic device by the electrochemical device, the electronic device may be further damaged. To avoid this disadvantage, fuses have been used in the related art to protect the electrochemical device from overcurrent. The fuse can sense overheating generated in abnormal operation of the electronic device, thereby cutting off a loop to prevent a fire.

Generally, a fuse includes a housing case, a first terminal, a second terminal, and a circuit breaking element. Wherein the housing case is provided in a case of the electrochemical device. The first terminal extends out of the accommodating shell and is connected with the first tab through a first conductive piece. The second terminal also extends out of the containing shell and is connected with an external circuit board through a second conductive piece; one end of the second conductive piece is connected to the second terminal, and the other end of the second conductive piece extends to a position close to the first terminal through one side of the accommodating shell departing from the shell. The circuit breaking element is arranged in the accommodating shell and is used for cutting off the physical connection relation between the first terminal and the second terminal when the temperature is equal to or higher than a preset threshold value; the circuit breaking element may be a bimetal or the like.

[ Utility model ] content

The inventor of the application finds out in the process of realizing the application that: the main body part of the current fuse, namely the accommodating shell is integrally arranged on the surface of the shell and is positioned between the shell and the second conductive piece, the accommodating shell has high temperature rise, and the heat dissipation is poor; the above factors make the overall heat dissipation performance of the fuse poor, which results in a low overcurrent capability of the fuse.

The present application is directed to a battery and an electronic device, so as to improve the current situation of poor heat dissipation performance of a housing case of a current fuse.

In order to solve the technical problem, the following technical scheme is adopted:

a battery includes an electrochemical device, a fuse, a first conductive member, and a second conductive member. The electrochemical device includes a housing including a sealing portion and a first tab extending out of the housing through the sealing portion. The fuse comprises an accommodating shell, a first terminal and a second terminal, wherein the first terminal is installed on the accommodating shell and at least partially exposed relative to the accommodating shell, and the second terminal is installed on the accommodating shell and at least partially exposed relative to the accommodating shell. And the first conductive piece is respectively connected with the first terminal and the first lug. The second conductive member is connected to the second terminal. At least a portion of at least one of the first conductive member and the second conductive member is located between the receiving case and the sealing part.

In the battery provided by the embodiment of the application, at least part of the first conductive member and/or the second conductive member is/are located between the accommodating shell of the fuse and the sealing part of the electrochemical device, and the accommodating shell has a larger distance from the sealing part, so that the accommodating shell can have better heat dissipation performance. That is, the battery can improve the current situation that the heat radiation performance of the accommodating case of the fuse is poor, and can improve the overcurrent capacity of the fuse to a certain extent.

In some embodiments, the housing case has a first surface and a second surface that are oppositely disposed in a thickness direction of the sealing portion, and the first surface is farther from the sealing portion than the second surface. And the first conductive piece and the second conductive piece are not arranged on one side of the first surface, which is far away from the sealing part.

This setting makes the fuse be the state of not being wrapped up by sealing part, first electrically conductive piece and the electrically conductive piece of second, and then is favorable to the fuse to deviate from one side of sealing part and has better heat dispersion.

In some embodiments, the first terminal extends out of the accommodating shell through a space between the first surface and the second surface, and the first conductive member is bent and includes a first portion, a bent portion, and a second portion that are sequentially connected. The first portion is connected to the first terminal, the second portion is located between the accommodating shell and the sealing portion and connected with the first tab, and the bent portion is located between the first portion and the second portion in the thickness direction of the sealing portion.

The first conductive piece is bent, so that the distance between the fuse and the sealing part is increased on the basis of connection with the first electrode lug, and the first conductive piece can be prevented from being bent to the side, deviating from the sealing part, of the fuse, so that the side, deviating from the sealing part, of the fuse is exposed, and the fuse has good heat dissipation performance.

In some embodiments, the second portion includes a first connecting segment and a first extending segment. The first connecting section is provided with a first end and a second end which are opposite, the first end is connected with the bent part, and the second end is the end of the first connecting section, which is far away from the bent part, and is positioned between the second terminal and the sealing part. One end of the first extension section is connected to the second end, and the other end of the first extension section extends along a second direction. The direction from the first end to the second end is a first direction, and the second direction is a direction intersecting with the first direction.

In some embodiments, one end of the second conductive member is connected to the second terminal, and the other end extends in the second direction.

In some embodiments, a projection of the second conductive member at least partially overlaps a projection of the second end in a thickness direction of the sealing portion. The arrangement is such that the second electrically-conductive member is substantially in the same position as the first tab.

In some embodiments, an end of the second conductive member facing away from the second terminal in the second direction is disposed beyond the first extension. Which facilitates the second conductive member being substantially flush with an end of the second tab remote from the electrode assembly; thus, the battery can be electrically connected with other elements through the second conductive member and the second lug.

In some embodiments, the fuse includes a third terminal disposed on the first surface or the second surface. One of the first terminal and the second terminal is connected to the third terminal. When the third terminal is disposed on the second surface, the third terminal can make the fuse more sensitive and timely break the circuit to protect the electrochemical device and the circuit board (not shown). When the third terminal is arranged on the first surface, the temperature rise of the third terminal is slow because the third terminal is far away from high-heat elements such as the sealing part and the first electrode lug, and the fuse can also radiate heat outwards through the third terminal, so that the fuse can be broken at a higher temperature, and the allowed current is higher.

In some embodiments, the housing shell has a first end and a second end opposite to each other, the first terminal protrudes out of the housing shell from the first end, and the second terminal protrudes out of the housing shell from the second end.

In some embodiments, the battery further comprises a third electrically conductive member. One end of the third conductive member is connected to the second terminal, and the other end of the third conductive member is connected to the second conductive member. The arrangement is favorable for selecting proper materials for the third conductive member under the condition that the materials of the second conductive member are inconvenient to weld to the second terminal, so that the third conductive member is suitable to be welded with the second terminal and the second conductive member at the same time.

In some embodiments, the housing case has a first surface and a second surface that are oppositely disposed in a thickness direction of the sealing portion, and the first surface is farther from the sealing portion than the second surface. The second terminal is at least partially exposed on the first surface, and the second conductive piece is connected with the part of the second terminal exposed relative to the first surface; or at least part of the second terminal is exposed relative to the second surface, and the second conductive piece is connected with the part of the second terminal exposed relative to the second surface.

In order to solve the technical problem, the following technical scheme is adopted:

an electronic device comprises the battery. The electronic device can also improve the condition that the accommodating shell of the fuse in the battery has poor heat dissipation because the battery is included.

Referring to fig. 1 to fig. 2, an exploded schematic view of a battery 1 and a perspective view of the battery 1 after hiding an electrochemical device 100 are respectively shown, wherein the battery includes the electrochemical device 100, a fuse 200, a first conductive member 300 and a second conductive member 400. The electrochemical device 100 includes a housing 110 and a first tab 130; the housing 110 includes a sealing portion 112, and the first tab 130 protrudes out of the housing 110 through the sealing portion 112. The fuse 200 includes a receiving case 210, a first terminal 220, and a second terminal 230; the first terminal 220 is mounted on the receiving shell 210, and at least a part of the first terminal is exposed relative to the receiving shell 210; the second terminal 230 is mounted on the receiving shell 210, and at least a portion of the second terminal is exposed relative to the receiving shell 210. The first conductive member 300 is connected to the first terminal 220 and the first tab 130, respectively; the second conductive member 400 is connected to the second terminal 230; at least a portion of the first conductive member 300 or at least a portion of the second conductive member 400 is positioned between the receiving case 210 and the sealing part 112.

Referring to fig. 1, the electrochemical device 100 includes a case 110, an electrode assembly 120, a first tab 130, and a second tab 140. Wherein the housing 110 is a container and mounting base for the remaining components in the electrochemical device 100; it includes a main body portion 111 and a sealing portion 112. The main body 111 is substantially a flat block shape, and has a receiving cavity for receiving the electrode assembly 120 and the electrolyte. The sealing part 112 has a sheet-like structure, and is formed to extend outward from the surface of the body part 111. The sealing portion 112 is a portion of the housing 110 that is sealed to prevent the receiving cavity from communicating with the external environment of the electrochemical device 100, thereby preventing the electrolyte from leaking; this may be achieved by two-part sheet bonding, heat-staking or other suitable means. It should be understood that, in other embodiments of the present application, the main body portion may also be made into other shapes such as a circle, an L shape, etc. according to actual use requirements, and the shape is not limited herein.

The electrode assembly 120 is a core element of the electrochemical device 100, and includes a first pole piece, a second pole piece, and a separator; the first pole piece and the second pole piece are opposite in polarity, and an isolation film is arranged between the first pole piece and the second pole piece for separation. In this embodiment, the electrode assembly 120 is a winding structure, and the first pole piece, the second pole piece and the isolation film are wound together to form a cylindrical structure with an oblong or elliptical cross section, so as to be conveniently accommodated in the accommodating cavity of the main body 111. It is understood that the electrode assembly 120 may be in a stacked structure in other embodiments of the present application, and the present application does not limit the structural form thereof.

The first tab 130 and the second tab 140, both of which have opposite polarities, are attached to the electrode assembly 120. In this embodiment, the first tab 130 is a flat strip structure, one end of which is connected to the first pole piece, and the other end of which extends out of the casing 110 through the sealing portion 112. The second tab 140 is a flat strip structure, one end of which is connected to the second tab, and the other end of which extends out of the housing 110 through the sealing portion 112. Thus, the electrochemical device 100 can form a loop with external elements through the first tab 130 and the second tab 140 to supply power or charge.

Referring to fig. 2, the fuse 200 is disposed opposite to the sealing portion 112, and includes a receiving case 210, a first terminal 220, and a second terminal 230. The housing case 210 is a mounting base of the remaining components in the fuse 200, and has a first surface 201 and a second surface 202 opposed to each other in the thickness direction Z of the sealing portion 112, and a side surface 203 between the first surface 201 and the second surface 202. The first surface 201 is farther from the sealing portion 112 than the second surface 202, that is, the first surface 201 is one of the two surfaces far from the sealing portion 112, and the second surface 202 is one of the two surfaces near the sealing portion 112. The side 203 extends from the first surface 201 to the second surface 202. The first terminal 220 has one end fixed to the housing 210 and the other end extending out of the housing 210 through the side 203 between the first surface 201 and the second surface 202 so as to be connected to the first conductive member 300. Similarly, one end of the second terminal 230 is fixed to the housing 210, and the other end of the second terminal extends out of the housing 210 through the side surface 203 between the first surface 201 and the second surface 202, so as to be connected to the second conductive member 400.

Specifically, the housing 210 has a first end 211 and a second end 212 disposed opposite to each other along the illustrated first direction X; that is, the first direction X is a direction in which the first end 211 points to the second end 212, and in the present embodiment, the first direction X is perpendicular to the thickness direction Z of the sealing portion 112. The first terminal 220 extends out of the housing 210 through the first end 211, and the second terminal 230 extends out of the housing through the second end 212. One of the first terminal 220 and the second terminal 230 constitutes an input terminal of the fuse 200, and the other constitutes an output terminal of the fuse 200. Optionally, the fuse is a thermal fuse (TCO); it is understood that in other embodiments of the present application, the fuse may be in other forms.

Referring to the first conductive element 300, referring to fig. 2, the first conductive element 300 is bent and includes a first portion 310, a bent portion 320, and a second portion 330 connected in sequence. The first portion 310 is connected to the first terminal 220; it may be connected to the side of the first terminal 220 away from the sealing portion 112 as shown in fig. 2, or may be connected to the side of the first terminal 220 facing the sealing portion 112. The second portion 330 is disposed between the receiving case 210 and the sealing part 112; the portion of the first portion 310 is disposed opposite the second portion 330. The bent portion 320 is curved, and the bent portion 320 is located between the first portion 310 and the second portion 330 along the thickness direction Z; the bent portion 320 is bent relative to the first portion 310 and the second portion 330. The second portion 330 includes a first connecting section 331 and a first extending section 332. The first connection section 331 includes opposing first and second ends 333, 334; the first end 333 is connected to the bending portion 320, and the second end 334 is an end of the first connecting section 331 away from the bending portion 320 and located between the second terminal 230 and the sealing portion 112. The first extension 332 has one end connected to the second end 334 and the other end extending away from the second end 334 along the second direction Y. Wherein, the "second direction" mentioned in the present document is a direction intersecting the first direction X; in this embodiment, the second direction Y is perpendicular to the thickness direction Z and the first direction X, but in other embodiments, the second direction may have other included angles with the thickness direction Z or the first direction X, and the disclosure is not limited thereto.

Referring to fig. 2, one end of the second conductive member 400 is connected to the second terminal 230, and the other end extends along the second direction Y. In the thickness direction Z, a projection of the second conductive member 400 at least partially overlaps a projection of the second end 334; that is, at least a portion of second conductive member 400 is disposed opposite second end 334. In addition, the second conductive member 400 is disposed away from the second terminal along the second direction Y and beyond the first extension 332, which is substantially flush with an end of the second electrode tab 140 away from the electrode assembly 120; thus, the battery can be electrically connected to other components through the second conductive member 400 and the second tab 140.

It should be noted that, in the present embodiment, the side of the fuse 200 away from the sealing portion 112 does not have the first conductive member 300 and the second conductive member 400; due to the arrangement, the fuse 200 is not wrapped by the sealing part 112, the first conductive piece 400 and the second conductive piece 400, and the side, away from the sealing part 112, of the fuse 200 has good heat dissipation performance.

In this embodiment, the battery 1 further includes a third conductive member 500, and the second conductive member 400 is indirectly connected to the second terminal 230 through the third conductive member 500. Specifically, one end of the third conductive member 500 is connected to the second terminal 230, and the other end is connected to the second conductive member 400. Optionally, the third conductive member 500 is welded to the second terminal 230, and the second conductive member 400 is welded to the third conductive member 500; this arrangement is advantageous in case that the material of the second conductive member 400 is not easily soldered to the second terminal 230, by selecting a suitable material for the third conductive member 500, so that the third conductive member 500 is suitable for soldering to the second terminal 230 and the second conductive member 400 at the same time. Of course, in other embodiments of the present application, the second conductive member 400 may also be directly connected to the second terminal 230.

In some embodiments, the fuse 200 also includes a third terminal 240. A third terminal 240 is disposed on the second surface 202; one of the first terminal 220 and the second terminal 230 is connected to the third terminal 240. The third terminal 240 may sense heat and transfer the heat to the first terminal 220 or the second terminal 230 connected thereto; in this manner, the third terminal 240 may make the fuse 200 more sensitive and timely open the circuit to protect the electrochemical device 100 and a circuit board (not shown). Of course, if it is necessary to increase the current that the fuse 200 can allow to pass, the third terminal 240 may be disposed on the first surface 201; since the third terminal 240 is far away from the high heat component such as the sealing portion 112 and the first tab 130, the temperature rise of the third terminal 240 itself is slow, and the fuse 200 can also radiate heat outwards through the third terminal 240, the fuse 200 is broken at a higher temperature, and the current allowed to pass through is also higher.

In other embodiments, the third terminal 240 may be used instead of the first terminal 220 or the second terminal 230, in which case one end of the third terminal 240 may not protrude out of the side surface 203 of the receiving case 210, and one surface of the third terminal may be a part of the first surface 201 or the second surface 202. When the battery comprises the first conductive member 300 and the second conductive member 400, the surface is electrically connected with one end of the first conductive member 300 or the second conductive member 400; when the battery further includes the third conductive member 500, the surface is electrically connected to one end of the first conductive member 300 or the third conductive member 500.

It should be understood that, even though the above-mentioned embodiment takes as an example that the first terminal 220 and the second terminal 230 respectively extend from two opposite ends of the receiving case 210 along the first direction X, and a portion of the first conductive member 300 extends between the receiving case 210 and the sealing part 112, a specific structure of the battery 1 is explained; however, the present application is not limited thereto, and in other embodiments of the present application, the first terminal 220, the second terminal 230, the first conductive member 300, and the second conductive member 400 may also be arranged in other manners; as long as it is ensured that the first terminal and the second terminal 230 are at least partially exposed from the accommodating shell 210, at least a portion of at least one of the first conductive member 300 and the second conductive member 400 is located between the accommodating shell 210 and the sealing portion 112, so as to provide a larger distance between the accommodating shell 210 and the sealing portion 112.

For example, in some embodiments, the first terminal 220 and the first conductive member 300 are disposed in the same manner as the embodiment shown in fig. 2, except that: one end of the second terminal 230 is mounted on the housing 210, and the portion mounted on the housing 210 is at least partially exposed on the first surface 201; the second conductive member 400 is connected to a portion of the second terminal 230 exposed at the first surface 201.

The second conductive member 400 is connected to the second terminal 230.

For another example, in some embodiments, the second terminal 230 and the second conductive member 400 are disposed in the same manner as the embodiment shown in fig. 2, except that: one end of the first terminal 220 is mounted on the housing 210, and the portion mounted on the housing 210 is at least partially exposed at the second surface 202; the first conductive member 300 is connected to a portion of the second terminal 230 exposed at the second surface 202.

Wherein at least a portion of the first conductive member 300 and/or the second conductive member 400 is located between the receiving case 210 of the fuse 200 and the sealing part 112 of the electrochemical device 100, the receiving case 210 has a larger distance from the sealing part 112, and thus the receiving case 210 has better heat dissipation performance. Therefore, the battery 1 can improve the current situation that the heat dissipation performance of the housing case of the current fuse is poor, so that the overcurrent capacity of the fuse can be improved to a certain extent.
