Precautions during product use
Ensure that the capacity of the negative electrode per unit area is greater than or equal to the capacity of the positive electrode per unit area to avoid lithium evolution during the charging process;
Ensure that there is a good interface between the isolation membrane and the electrode;
The areal density and compaction density of the electrode will affect the rate capacity and performance;
It is recommended to use the formula "active material: conductive agent: CMC: SBR=95.0: 1.3: 1.4: 2.3" (customers can make a reasonable design according to their own process)
