Description

Technical Field

[0001] The utility model relates to the technical field of lithium batteries, in particular to an insulating gasket for a lithium battery. Background Art

[0002] Lithium batteries use lithium metal or lithium alloy as the anode material and a non-aqueous electrolyte solution. Unlike lithium-ion batteries, lithium batteries are primary batteries, while lithium-ion batteries are rechargeable. Due to the highly reactive chemical properties of lithium metal, the processing, storage, and use of lithium metal place very high demands on the environment. As a result, lithium batteries have not been widely used for a long time. Lithium batteries require gaskets for insulation and protection when in use.

[0003] After searching, the applicant discovered that a Chinese patent disclosed "a lithium battery insulating gasket", and its publication (announcement) number is "CN 218385674 U". This patent mainly uses a refrigeration component to cool the thermally conductive gasket to improve the heat dissipation effect between batteries; the insulating fabric layer is used to isolate the lithium battery from the gasket body to prevent the lithium battery short circuit caused by the shell voltage between batteries; the utility model can not only improve the heat dissipation effect between batteries, but also has a good insulation effect to prevent the problem of lithium battery short circuit caused by the shell voltage between batteries. However, the device uses a refrigeration component to cool the battery. Although the cooling effect is achieved, due to the close contact with the battery, it is easy to cause damage to the battery body, and in the case of unstable installation of the lithium battery, we propose a lithium battery insulating gasket.
