Product Details

Product Description

 

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.

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, ): made of SS304
Dimensions (Dia x Height) 20mm x 3.2mm

 

Application
  • Excellent for developing new Li-ion rechargeable batteries up to 5.5V because of Al-cladding
