Hot pressing process
The thickness of bare battery is controlled by setting reasonable time, temperature and pressure.
Hot pressing purpose
Make the loose naked battery shape fixed after winding to prevent the relative displacement of the positive and negative electrode pieces;
Improve the flatness of the core, so that the thickness of the core meets the requirements and has high consistency;
Eliminate the diaphragm wrinkles, drive out the air in the battery core, make the diaphragm and the positive and negative electrode closely fit to shorten the lithium ion diffusion distance, reduce the battery internal resistance.
Main control points
1. Hot pressure control, maintain the consistency of the battery; 2. Temperature stability 3. Diaphragm permeability, thickness changes 4. The core thickness to meet the requirements of bright 5. Whether the pole piece is broken
