Description

technical field [0001] The invention relates to the field of lithium batteries, in particular to a heat dissipation device for lithium batteries. Background technique [0002] Lithium battery is a type of battery that uses lithium metal or lithium alloy as the negative electrode material and uses non-aqueous electrolyte solution. Due to the very active chemical properties of lithium metal, the processing, storage and use of lithium metal have very high environmental requirements. Therefore, Lithium batteries have not been used for a long time. With the development of science and technology, lithium batteries have become the mainstream now. Lithium batteries can be roughly divided into two categories: lithium metal batteries and lithium ion batteries. Lithium metal batteries generally use manganese dioxide as the positive electrode material, metallic lithium or its alloy metals as the negative electrode material, and use non-aqueous electrolyte solutions; lithium ion batterie...
