Description

Technical Field

[0001] The present invention belongs to the technical field of energy storage equipment, and specifically relates to an adjustable temperature-controlled energy storage equipment battery cell, a laminated battery cell and a composite power battery cell. Background Art

[0002] Lithium battery heating is a common phenomenon in life. It often occurs in wireless home appliances such as mobile phones and laptops that use lithium batteries as power sources. When the lithium battery is discharged, a chemical reaction will occur inside the battery, generating a large amount of heat energy, causing the battery temperature to rise. We can feel the temperature when we touch it with our hands. This is a common phenomenon in most lithium batteries.

[0003] The main hazards of heating to lithium batteries are:

[0004] 1. Long-term overheating of the battery will cause the temperature of the internal components to rise, affecting the normal operation of the components;

[0005] 2. If the battery is heated for a long time, the heat of the battery itself will increase. If it is a sealed battery, the air inside it will expand violently, causing the battery to bulge outward, and in severe cases, the battery will explode;

[0006] 3. Long-term excessive heating of the battery will accelerate the aging process of the product itself and shorten its life.

[0007] In actual use, the battery is generally placed in a sealed box. If the heat generated by the lithium battery cannot be discharged in time through the box, the temperature inside the box will rise, posing a safety risk. Summary of the invention
