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=*5.0: 1.3: 1.4: 2.3" (customers can make
a reasonable design according to their own process)
