CR2032 Al-Clad Coin Cell Cases Can with Aluminum coating
L-Al-2032 is a special CR2032 coin cell case with Aluminum coated on the inside of the positive can. 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.
L-Al-2032 Al-Clad Coin Cell Cases
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
The advantage of the 316ss model: 316ss and 304ss on the chemical composition of the main difference is that 316SS contains Mo, and generally accepted, the 316 has better corrosion resistance, more resistant to corrosion under high temperature environment.
Remark: When you order more than 5000sets, Our also can put your company Logo on to case and give you the wholesale price .
