The field such as electricity and energy storage, it has also become the main body of domestic and international battery development and application, so as to lithium ion battery
Cycle life and security are proposed higher requirement.Influenceing all of lithium ion cycle life and security
In multifactor, moisture is one of most important of which influence factor.Electrolyte is very sensitive to moisture, excessive
Moisture react caused by HF can corrode inside lithium ion cell structure, particularly to lithium ion battery
Cycle life causes strong influence, while caused gas easily causes lithium ion battery expansion, to lithium
The security performance of ion battery brings very big influence.Therefore, the moisture inside lithium-ion battery system is controlled
Content is the important goal of lithium ion battery manufacture process control.
In lithium ion battery production process, battery is before electrolyte is filled, it is necessary to enters the battery core in battery
Row heat drying, to reduce battery core internal moisture content, avoid the electrolyte after fluid injection that side reaction occurs with water,
Influence the cycle performance and security performance of battery.
