Description

technical field [0001] The invention relates to the technical field of lithium batteries, in particular to a novel lithium battery heat dissipation and heat preservation system. Background technique [0002] Lithium battery is a type of battery that uses lithium metal or lithium alloy as the negative electrode material and uses a non-aqueous electrolyte solution. Lithium batteries can be roughly divided into two categories: lithium metal batteries and lithium ion batteries. Li-ion batteries do not contain metallic lithium and are rechargeable. Lithium-ion batteries generally use lithium alloy metal oxides as positive electrode materials, graphite as negative electrode materials, and non-aqueous electrolytes. With the increasing capacity of lithium batteries, the problem of heat dissipation has become increasingly difficult. [0003] With the increasing energy crisis and environmental pollution, the replacement of traditional engine vehicles by new energy vehicles has beco...

Problems solved by technology

Under the condition of low temperature, 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
