This is a special CR2032 coin cell case with Aluminum coated on the inside of the positive can (10pcs/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).

Specifications
MaterialStainless Steel 304 with the Aluminum coating:
  • Aluminum-Clad on inside of the POSITIVE case (bottom part, larger, connects to the Cathode with Al current collector), to prevent electrolyte from reacting with steel during high voltage charging > 4.5V.
  • Negative case (top part with insulating O-ring, smaller, connects to Anode with Cu current collector): made of SS304, you may need to put Spring/Spacer in between this case and anode.
  • Sealing Gasket: PP
Dimensions (Dia x Height)20mm x 3.2mm
Optional Please click the picture below to order Al spacer and spring
    


Application
  • Excellent for developing new Li-ion rechargeable batteries up to 5.5V because of Al-cladding
  • Warning: Please never use water clean Al clad case to avoid Aluminium coating oxidization. Please keep the case in vacuum or glove box if not using for a long time.
  • Do not clean the Al clad case with ultrasonic cleaners. Please clean with alcohol if cleaning is needed.
  • We only promise MTI crimper can make good sealing, not guaranty for the other brand crimper
