Abstract
The invention provides a fireproof cover applied to a battery, wherein the battery comprises an anode and a cathode, the fireproof cover is arranged on the anode of the battery, and a fireproof material is arranged in the fireproof cover.
Description
Technical Field
The present invention relates to a fire-proof cover, and more particularly, to a fire-proof cover applied to a battery.
Background
The battery has the function of storing electrical energy. A plurality of batteries are connected in series or in parallel to form a battery device, which can be used as a power supply source of electronic machines, such as an electric vehicle.
When the battery is impacted by external force, high-heat flame can be sprayed out, and the high-heat flame can be burnt to other battery cores, so that the battery device is exploded. In the past, a plurality of insulating plates can be arranged inside the battery device, and the insulating plates are used for separating a fireproof channel. The cells are isolated from each other by a fire-proof channel. When one of the batteries in the battery device is damaged (e.g., the battery is punctured or damaged) to generate a flame, the fire-proof channel can serve as a barrier to prevent smoke, heat or flame formed by the damaged battery from being conducted to the front and rear batteries, and to guide the smoke, heat or flame formed by the damaged battery to the outside of the battery device, so as to reduce the chance of ignition.
The use of an insulating plate to separate the fire-blocking passages can reduce the chance of battery burn, but a sufficiently long fire-blocking passage is required to effectively direct smoke, heat, or flame from the damaged battery to the outside of the battery device. In addition, the fire-proof channels are separated by the insulating plates, and the fire-proof channels will increase much extra space, so that the volume of the battery device cannot be effectively reduced, thereby causing inconvenience in the application of the battery device.
Disclosure of Invention
The technical problem to be solved by the invention is to provide a fireproof cover, wherein the fireproof cover is arranged on a positive electrode of a battery, and a fireproof material is arranged inside the fireproof cover; when the battery is damaged and flame is emitted from the positive electrode, the fireproof material in the fireproof cover expands under heat and generates carbon dioxide, and the flame is extinguished by the carbon dioxide generated by the fireproof material; in addition, the expanded fireproof material can cover the positive electrode to play the roles of heat insulation and oxygen insulation, thereby achieving the flame retardant effect.
In order to achieve the above object, the present invention provides a fire-proof cover applied to a battery, the battery includes a positive electrode and a negative electrode, the fire-proof cover is disposed on the positive electrode of the battery, wherein a fire-proof material is disposed inside the fire-proof cover, and the fire-proof material will expand when exposed to a high temperature environment and generate carbon dioxide.
In an embodiment of the present invention, the battery is a lithium battery.
In an embodiment of the present invention, the fireproof material is a carbon material.
In one embodiment of the present invention, the fireproof material is a graphite material or other material that generates carbon dioxide when exposed to high temperature.
In one embodiment of the present invention, the fire-proof cover includes a plurality of micro-air vents.
In an embodiment of the invention, a circular hole is formed in the center of the fireproof cover, and the anode of the battery is exposed from the circular hole.
In an embodiment of the invention, the fireproof cover is also arranged on the negative electrode of the battery.
The invention has the beneficial effects that: when the battery is damaged and flame is emitted from the positive electrode, the fireproof material in the fireproof cover expands under heat and generates carbon dioxide, and the flame is extinguished by the carbon dioxide generated by the fireproof material; in addition, the expanded fireproof material can cover the positive electrode to play the roles of heat insulation and oxygen insulation, thereby achieving the flame retardant effect.

Detailed Description
The invention will be described in detail with reference to the following drawings, which are provided for illustration purposes and the like:
referring to fig. 1, fig. 2, fig. 3 and fig. 4, a perspective view of an embodiment of the battery of the present invention, a cross-sectional view of an embodiment of the battery of the present invention, an enlarged view of a region a of fig. 2 and a top view of an embodiment of the battery of the present invention are respectively shown. Referring to fig. 1, 2, 3 and 4, the battery 10 of the present invention may also be a lithium battery, which includes a positive electrode 11 and a negative electrode 13. A fire-resistant cover 20 may be fitted over the positive electrode 11 of the battery 10. The fire-proof cover 20 is a circular cover body, and a circular hole 21 is formed in the center of the top surface of the fire-proof cover. When the fireproof cover 20 is sleeved on the positive electrode 11 of the battery 10, the positive electrode 11 of the battery 10 is exposed from the circular hole 21. Further, a plurality of micro air vents 23 are provided around the circular hole 21 of the fire-proof cover 20. When the gas valve of the positive electrode 11 of the battery 10 releases the pressure, the released high-pressure gas is discharged from the gas discharge hole 23 of the fireproof cover 20.
The battery 10 of the present invention further includes a fire-blocking material 30 disposed inside the fire-blocking cover 20. The fire-blocking material 30 may also be a carbon-based material, such as graphite, which will expand and combine with oxygen in the air to produce carbon dioxide in a high temperature environment (e.g., a high temperature environment generated by a flame). When the fireproof cover 20 is fitted over the positive electrode 11 of the battery 10, the annular fireproof material 30 is tightly attached to the positive electrode 11 of the battery 10 and surrounds the positive electrode 11 of the battery 10. In the present invention, the fire-proof material 30 may be selected from other materials that generate carbon dioxide when exposed to high temperature, besides carbon group materials.
When the battery 10 is damaged (e.g., the battery 10 is punctured or knocked down) to generate a flame at the positive electrode 11, the fireproof material 30 in the fireproof cover 20 will expand rapidly by heat and generate carbon dioxide. The carbon dioxide generated by the fire-blocking material 30 will then extinguish the flame emitted at the positive electrode 11 to avoid the chance of flame spread. In addition, the expanded fireproof material 30 covers the positive electrode 11 to play a role in heat insulation and oxygen insulation, so that the flame retardant effect is achieved.
A fire-resistant cover 20 with a fire-resistant material 30 can likewise be provided at the location of the negative electrode 13 of the battery 10, as shown in fig. 5. When a flame is emitted from the negative electrode 13, the fire-proof material 30 in the fire-proof cover 20 may also expand by heat and generate carbon dioxide, and the flame at the negative electrode 13 is extinguished by the carbon dioxide generated by the fire-proof material 30.
In an embodiment of the present invention, the fireproof cover 20 and the positive electrode 11 of the battery 10 are independent components, and the fireproof cover 20 is fixed on the positive electrode 11 of the battery 10 in a sleeving manner. Alternatively, in another embodiment of the present invention, the fireproof cover 20 and the positive electrode 11 of the battery 10 may be directly manufactured together and formed as an integral member.
The present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof, and it should be understood that various changes and modifications can be effected therein by one skilled in the art without departing from the spirit and scope of the invention as defined in the appended claims.
