ABSTRACT:
A method for producing a rechargeable button cell having a negative electrode composed of a lithium/indium alloy, a positive lithium/intercalating electrode and an organic electrolyte, a lithium layer and an indium layer are introduced into a negative housing half-section. The positive electrode material is introduced into a positive housing half-section. The two housing half-sections are beaded to form the button cell once the organic electrolyte has been added and a separator has been placed in between, with a seal being inserted between the housing half-sections. A lithium-indium alloy is formed from the lithium layer and the indium layer by storage or a subsequent charging/discharge cycle.
