Non-conductive 25µm Battery pp Separator AOT Celgard 3501 for Lithium Battery, thickness: 5um, dimensions: 60mm L x 20m L
The main function of
the separator is to separate the positive and negative electrodes of the
battery to prevent short circuit due to contact between the two
electrodes, and also has the function of allowing electrolyte ions to
pass through. The separator material is non-conductive, and its physical
and chemical properties have a great impact on the performance of the
battery.
