(EP925612-A1)      An Li or Li-ion rechargeable battery with improved cycling performance and a nominal voltage of 4 V comprises: (i) an anode of Li optionally alloyed with other metals or of an electroconductive material which intercalates Li; (ii) a non-aqueous electrolyte; and (iii) a cathode based on a manganese spinel, where part of the manganese is substituted by Ga, of formula LiGaxMn2-xO4 (x = 0-0.1).    USE -   Used in place of lead-acid and NiCd batteries, in consumer electronics such as camcorders, in fixed appliances such as telephone exchanges and alarm systems, or for electric vehicles.    ADVANTAGE -   The battery capacity is maintained sufficiently during cycling, without any significant initial loss in capacity.
