Abstract

The invention discloses a pole for a large battery, a hole channel is arranged in the pole, an outlet of the hole channel is arranged on the outer side of the pole protruding out of a battery shell, and hot / cold fluid circulates in the hole channel. When the temperature of the battery cell is too high, cold fluid can be injected from the inlet pipe; when the temperature of the battery cell is too low, the hot fluid can be injected from the inlet pipe, so that the battery can work within the optimal temperature range.

Description

technical field [0001] The present application relates to the technical field of lithium batteries, in particular to a pole for a large battery. Background technique [0002] In recent years, lithium battery technology has developed rapidly and has been used in more and more fields. However, due to the principle and structural characteristics of lithium batteries, they often generate heat due to internal resistance and other reasons during repeated use, generating a large amount of heat, and the heat will gradually increase. If the accumulated heat cannot be effectively dissipated, it will affect the stability of the battery and shorten the service life of the lithium battery. As the temperature rises further, the electrolyte, solvent, and positive and negative electrode materials inside will decompose, burn, and explode. Low temperature will reduce the conductivity of the electrolyte, the ability to conduct active ions will decrease, the impedance will increase, and the c...
