ACCUMULATORE ERMETICO DEL TIPO LEGA DI LITIO/SOLFURO METALLICO, AD ELETTRODI BIPOLARI

A storage battery of lithium alloy/metal sulphide type consists of one or more stacked cells, each of which consists of a cathode (2) and an anode (1) separated from each other by a ceramic separator (3) which insulates the electrodes and supports the electrolyte, consisting of a mixture of fused salts of suitable composition. Each constituent cell of the battery is hermetically sealed. Two adjacent cells have for the two electrodes of opposite polarity a common current collector consisting of a metal plate (6) welded to the cup (7,8) containing the active electrode material. A perforated metal plate (10) is interposed between the electrode separator (3) and each of the two electrodes (1,2) to retain the active material forming the electrodes.
