Item Number: CR2032CASE-AL2s

Quantity:

This is a special CR2032 coin cell case with Aluminum coated on the inside and outside of the positive can (60pcs/pack). It can tolerate polarization of higher voltages (up to 5.5V) due to the passivation of cladding 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. For more information on this Al-Clad coin cell case, please read a testing report by Dr. John B. Kerr's Research Group from the Lawrence Berkeley National Laboratory (LBL). MTI would like to extend our special thanks to Dr. John B. Kerr and Dr. Li Yang for their contributions and findings in this test.
