Product Details

The Specification is 20d x 3.2mm

This is a special CR2032 coin cell case with Aluminum coated on the inside of the positive can (20pcs/pck). It can tolerate polarization of higher voltages (up to 5.5V) due to the passivation of can by electrolyte component (especially LiPF6 based electrolyte system) to form a layer of AlF3. This AlF3 layer is thin enough (several angstroms) to allow electron tunneling, and simultaneously blocking the dissolution of Al3+ into the electrolyte.
