In the multiple production processes of lithium batteries, the positive and negative electrodes, batteries and batteries are vacuum baked several times to remove the moisture as much as possible.
Since the moisture content in the lithium battery must be strictly controlled, moisture has a great impact on the performance of the lithium battery, including voltage, internal resistance, self-discharge and other indicators.
Excessive moisture content can lead to product rejection, quality degradation, and even product explosion.
Therefore, in the multiple production processes of lithium batteries, the positive and negative electrodes, batteries and batteries must be vacuum baked several times to remove the moisture as much as possible.
