{"product_id":"cr2032-case-al2s","title":"Al-Clad CR2032 Coin Cell Case (20d x 3.2mm) for Li-ion Battery for \u003e 4.5V - 60 Sets\/pck-CR2032CASE-AL2S","description":"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.
