STIFF COMPARTMENT OF NEGATIVE ELECTRODE FOR METAL-AIR BATTERY AND METHOD OF ITS MANUFACTURING Russian patent published in 2013 - IPC H01M12/08 H01M2/02 H01M2/30 H01M4/72 H01M4/1395 

FIELD: electricity.

SUBSTANCE: invention relates to a precursor of a compartment of a negative electrode for rechargeable metal-air batteries, comprising a stiff body (1), at least one membrane (2) of solid electrolyte, a protective coating (5) fully covering the inner surface of the membrane (2) of solid electrolyte, a metal current collector (3), pressed to the inner surface of the protective coating (5), and also preferably a unit (4) of elastic material pressed to the current collector and substantially filling all internal space formed by walls of the rigid body and solid electrolyte (2), and also a flexible electronic conductor (6), tightly stretching via one of the walls of the stiff body. This invention also relates to a compartment of a negative electrode with a stiff body produced from the specified precursor, and to a battery comprising the specified compartment of the negative electrode. The suggested "precursor" corresponds to the empty compartment of the negative electrode, which is filled as a result of an electrochemical reaction and has sufficient mechanical strength.

EFFECT: availability of the specified compartment makes it possible to increase efficiency of a battery.
