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 clad 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.

Specifications
Material Stainless Steel 304 with the Aluminum coat:
  • 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 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
