Al-Clad CR2032 Coin Cell Can (20d x 3.2mm) for Secondary Li-ion Battery

Al-Clad CR2032 Coin Cell Can (20d x 3.2mm) for Secondary Li-ion Battery up to 5.5V- EQ-CR2032-CASE-316A Al-Clad CR2032 Coin Cell Can (20d x 3.2mm) for Secondary Li-ion Battery up to 5.5V- EQ-CR2032-CASE-316AThis is  a special CR2032 coin cell case with Aluminum coated on the inside of the positive can. It can tolerate higher voltages (up to 5.5V) polarization due to the passivation of can by electrolyte component (especially LiPF6 based electrolyte system) to form a layer of AlF3. This AlF3 is thin enough (several angstrom) to allow electron tunneling, and blocking the dissolution of Al3+ into the electrolyte.Please kindly read a testing report on this Al-Clad coin cell case by Dr. John B. Kerr's Research Group from Lawrence Berkeley National Laboratory (LBL) and our special thanks to Dr. John B. Kerr and Dr. Li Yang. SpecificationsCR2032 case is made of  SS316 stainless steelAluminum is clad on inside of Positive case (Bottom part (larger) connects to Cathode with Al current collector), to prevent electrolyte from reacting with steel during > 4.5V high voltage chargingNegative case (Top part with insulating O-ring, smaller,connects to Anode with Cu current collector): made of SS316, you may need to put Spring/Spacer in between this case and anode.Dimension (Dia X H): 20mm x 3.2mmWeight: 0.1Oz (2.8grams)Excellent for developing new Li-ion rechargeable battery up to 5.5V because of Al-clad positive case
