[0018]

The present invention provides an exhaust structure of a lithium battery, as shown in FIGS. 1 and 2, respectively, which are the first and second embodiments of the present invention, as shown in FIGS. 5 and 6 respectively. The fourth embodiment, as shown in Figs. 3 and 4, is another view of the second embodiment.

[0019]

1 is a schematic cross-sectional view showing a first embodiment of the present invention. The exhaust structure of the lithium battery of the present invention comprises: a package bag 1, a battery core 2, and at least one one-way exhaust valve 3.

[0020]

The package bag 1 is made of a flexible material and has a plurality of sides. In detail, the package bag 1 can be a sealed bag body made of an aluminum plastic film material, mainly after the sealed bag body is folded in half, except for the folded edge 14 The other three sides are edge-sealed by hot pressing or bonding to form three sealing edges 11, 12, 13, respectively, and an accommodation is formed between the three sealing edges 11, 12, 13 and the opposite folding edges 14. The space 16 is disposed in the accommodating space 16 and houses an electrolyte (not shown or labeled).

[0021]

The battery core 2 is housed in the accommodating space 16 of the package bag 1 to bring the battery cell 2 into contact with the electrolyte. The battery core 2 is further connected with a positive conductive handle 211 and a negative conductive handle 221, and the positive conductive handle 211 and the negative conductive handle 221 respectively protrude out of the sealing edge 12 of the package bag 1 to facilitate interaction with a portable electronic device. (not shown) Electrical connection.

[0022]

The one-way exhaust valve 3 is disposed in the package bag 1 and communicates between the accommodating space 16 and the outside. The one-way exhaust valve 3 can be disposed at any position of the package bag 1 as long as it can communicate with the accommodating space 16 and the outside world. Therefore, even at least one one-way exhaust valve 3 is disposed in the package bag 1 At least one side of the present invention is also included in one of the many possible solutions of the present invention. In detail, at least one of the three sealing edges 11, 12, 13 and the opposite flange 14 can be provided with at least one one-way exhaust valve 3. In the present embodiment, a one-way exhaust valve 3 is disposed on each side as an example. A one-way exhaust valve 3 (not shown) may be disposed on each side of the polygon, or a single side may be separately provided. To the exhaust valve 3 (shown in Figure 1), the invention is not limited.

[0023]

As shown in FIG. 1, the one-way exhaust valve 3 is disposed on the opposite side 14 of the package bag 1, and the folded side 14 is thus formed with a hole body 141 surrounding the outer circumference of the one-way exhaust valve 3, while making a single The exhaust valve 3 is connected between the accommodating space 16 and the outside to facilitate the exhaust. Further, the one-way exhaust valve 3 may be a check valve, but the present invention is not limited as long as it can be vented in one direction.

[0024]

Referring to FIG. 3 , the battery core 2 includes at least one positive electrode sheet 21 stacked on each other, at least one negative electrode sheet 22 , and at least one separator 23 sandwiched between any adjacent positive electrode sheet 21 and the negative electrode sheet 22 . The positive electrode sheet 21 is electrically connected to the positive electrode conductive handle 211, the negative electrode sheet 22 is electrically connected to the negative electrode conductive handle 221, and the separator 23 is used to prevent the positive electrode sheet 21 and the negative electrode sheet 22 from contacting each other.

[0025]

Thereby, when the lithium battery is energized, even if a gas is generated between the battery core 2 and the electrolyte due to a chemical reaction, the pressure of the package bag 1 inflated into the bag by the gas is greater than the preset pressure of the one-way exhaust valve 3. When the one-way exhaust valve 3 discharges the gas in the accommodating space 16 to the outside, the package bag 1 is only moderately expanded, so that the problem of deformation and expansion of the lithium battery can be surely avoided. Furthermore, when the lithium battery generates gas again, the one-way exhaust valve 3 can still be used to discharge the gas exceeding the preset pressure in the accommodating space 16 to the outside, in other words, the one-way vent valve 3 can Unlimited help with lithium battery exhaust.

[0026]

2, 3 and 4 are schematic cross-sectional views and partial enlarged views of a second embodiment of the present invention. The structure of the second embodiment is substantially the same as that of the first embodiment except that the second embodiment further includes a water absorbing material member 4.

[0027]

As shown in the figure, a water absorbing space 17 is further formed between the three sealing edges 11, 12, 13 and the opposite side of the package bag 1, and the accommodating space 16 and the water absorbing space 17 communicate with each other to enable the one-way exhaust valve 3 to pass through The water absorbing space 17 communicates with the accommodating space 16.

[0028]

The water absorbing and permeable member 4 is housed in the water absorbing space 17 to facilitate adsorption of the electrolyte that has passed through the absorbing space 17 and is originally attached to the gas; of course, the gas is directly infiltrated into the absorbing space 17 by the accommodating space 16 without passing through the gas. The liquid can also be absorbed by the absorbent article 4. The water absorbing material 4 can be a cotton flower, a capillary structure or any other object having both water absorption and gas permeable effects. The invention is not limited, and the capillary structure is disposed in the water absorbing space 17 as shown.

[0029]

Thereby, when gas is generated in the accommodating space 16 of the lithium battery, the unidirectional exhaust is performed when the package bag 1 is inflated by the gas (see FIG. 3) until the pressure in the bag is greater than the preset pressure of the one-way vent valve 3. The valve 3 discharges the gas in the accommodating space 16 to the outside through the absorbing space 17, so that the second embodiment of the present invention can not only discharge the gas in the accommodating space 16 (having the same effect as the first embodiment). The electrolyte which is originally attached to the gas can be adsorbed by the water absorbing and permeable member 4, in other words, the gas discharged from the one-way vent valve 3 is a gas which is dry and does not have an electrolyte, so that the electrolyte does not ooze out. Or with the gas.

[0030]

In addition, as for the manner of separation between the accommodating space 16 and the absorbing space 17, as shown in FIG. 2 and FIG. 3, the package bag 1 has a spacer 15 separated between the accommodating space 16 and the absorbing space 17, and is separated. The strip 15 is provided with at least one venting opening 150 for allowing the accommodating space 16 and the absorbing space 17 to communicate with each other. In this embodiment, a first spacer 151 and a second spacer 152 may be hot-pressed or bonded to the package bag 1 respectively, and the first spacer 151 and the adjacent end of the second spacer 152 are connected. The vent holes 150 are formed to be spaced apart from each other, and the first spacer 151, the second spacer 152, and the vent holes 150 collectively constitute the spacer 15.

[0031]

As shown in FIG. 4, the one-way exhaust valve 3 of the first embodiment and the second embodiment mainly includes a hollow outer casing 31, a piston 32, a retaining ring 33, and an elastic member 34. The hollow casing 31 has an air inlet 311 and an air outlet 312 communicating with each other; a corresponding air inlet 311 in the hollow casing 31 is provided with a passage 314; and a position away from the air inlet 311 is provided in the hollow casing 31. The retaining ring 33; the piston 32 is movably moved between the passage 314 and the retaining ring 33 in the hollow casing 31, and the plug 321 of the piston 32 is further provided with a T-shaped passage communicating between the passage 314 and the air outlet 312. 322; the elastic member 34 is elastically supported between the piston 32 and the retaining ring 33.

[0032]

When the pressure inside the bag of the package bag 1 is still less than the preset pressure of the one-way exhaust valve 3 (the elastic supporting force of the elastic member 34), the elastic support of the elastic member 34 causes the plug 321 of the piston 32 to be correspondingly plugged. The passage 314 (not shown), in other words, the gas in the accommodation space 16 will not be able to push the piston 32 and therefore cannot be vented.

[0033]

When the pressure inside the bag of the package bag 1 is greater than the preset pressure of the one-way exhaust valve 3, the gas in the accommodating space 16 will push the piston 32, causing the plug 321 of the piston 32 to retreat from the aforementioned passage 314 (see FIG. 4). At this time, the gas in the accommodating space 16 will pass through the passage 314 and the aforementioned T-shaped passage 322, and then discharged from the air outlet 312 of the one-way exhaust valve 3.

[0034]

FIG. 5 is a cross-sectional view showing a third embodiment of the present invention. The structure of the third embodiment is substantially the same as that of the second embodiment, and the difference is only in the third embodiment that the one-way exhaust valve 3 is changed to one of the three sealing sides 11, 12, 13. In the present embodiment, the one-way exhaust valve 3 is described by taking the sealing edge 13 disposed in the three sealing edges as an example. Therefore, the sealing edge 13 is also formed to be surrounded by the single. a hole 131 to the outer periphery of the exhaust valve 3; and second, the spacer 15 is disposed adjacent to the sealing edge 13 to form a water absorbing space 17 between the spacer 15 and the sealing edge 13, thereby also having The same as the exhaust gas of the second embodiment and the adsorption of the electrolyte.

[0035]

FIG. 6 is a cross-sectional view showing a fourth embodiment of the present invention. The structure of the fourth embodiment is substantially the same as that of the second embodiment, and the difference is only in the fourth embodiment that the water absorbing and permeable member 4 is reconfigured in the one-way exhaust valve 3a.

[0036]

As shown in the figure, in the one-way exhaust valve 3a, the hollow casing 31 is provided with a water absorbing space 313 connected to the air inlet 311 and the passage 314 corresponding to the air inlet 311, and the water absorbing material 4 is accommodated in the water absorbing material. Within space 313.

[0037]

Therefore, when the package bag 1 discharges the gas from the accommodating space 16, the absorbing material 313 of the one-way venting valve 3a is first passed through the absorbing space 313 of the one-way venting valve 3a, so that the absorbing material 4 is first adsorbed to the electrolyte originally attached to the gas, and then dried. The gas without the electrolyte is discharged from the gas outlet 312 of the one-way exhaust valve 3a, thereby also having the same exhaust gas as the second embodiment and the effect of adsorbing the electrolyte.

[0038]

In summary, the present invention has the following effects as compared with the prior art: the package bag 1 in the lithium battery can immediately use the one-way exhaust valve 3, 3a to discharge excess gas when a certain amount of gas is generated.
