Abstract

The invention concerns a process for the production of a porous lithium cobaltite electrode plate with a large inner surface and low polarization resistance. Lithium carbonate powder and cobalt metal powder are uniformly mixed together and then films are produced from the mixture and plates from the films, which plates are sintered and then placed in an air stream for several hours at a temperature between 400.degree. C. and 488.degree. C. until the conversion of said plates to lithium cobaltite electrode plates with an extremely large inner surface has taken place.
