Description

technical field [0001] The invention relates to the technical field of heat dissipation and heat preservation of lithium batteries, in particular to a heat dissipation and heat preservation system of lithium batteries. Background technique [0002] Lithium battery is a kind of battery that uses lithium metal or lithium alloy as negative electrode material and uses non-aqueous electrolyte solution. Lithium batteries can be roughly divided into two categories: lithium metal batteries and lithium ion batteries. Lithium-ion batteries do not contain lithium in the metallic state and are rechargeable. Lithium-ion batteries generally use lithium alloy metal oxides as positive electrode materials, graphite as negative electrode materials, and use non-aqueous electrolytes. With the increasing capacity of lithium batteries, the problem of heat dissipation has become increasingly difficult. Under these conditions, the available capacity of the battery decreases and the discharge capa...

AI Technical Summary

Problems solved by technology

Lithium-ion batteries generally use lithium alloy metal oxide as the positive electrode material, graphite as the negative electrode material, and non-aqueous electrolyte. As the capacity of lithium batteries increases, the heat dissipation problem becomes increasingly difficult. Under these conditions, the available capacity of the battery decreases, and the discharge capacity decreases, resulting in a decrease in the cruising range of the electric vehicle. Under the condition of high temperature, the output power of the lithium battery increases, and the self-discharge rate increases, which damages the performance of the battery. Excessive temperature will destroy the internal chemical balance of the battery and reduce the cycle life of the battery. For this reason, we propose a heat dissipation and heat preservation system for lithium batteries
