A mercury-free alkaline button cell battery, includes an anode plate, a cathode cap, a cathode zinc paste, a seal ring, an anode case and a membrane. A layer of indium or tin is plated on the cathode plate, and indium is added into the zinc paste to replace mercury. A layer of indium or tin is plated on the cathode plate to prevent zinc in the cell from contacting other material or metal, to avoid swelling that could result in the release of gas. |
