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)
