LITHIUM CELL BATTERY

摘要

The invention concerns an electrochemical lithium cell battery (10; 12; 14) comprising at least one positive electrode (5, 6), at least one liquid electrolyte including at least one lithium salt, and at least one negative electrode (1, 2) Said cell battery (10; 12; 14) is characterized in that it comprises at least one layer (3, 13) of a gelled separator (SG) comprising at least one polymer (PG), capable of being gelled by the liquid electrolyte, which is at least partly gelled by the liquid electrolyte, in contact with the negative electrode (1, 2), and in that it comprises at least a layer (4) of a plasticized separator (SP), including at least one polymer (PP) capable of being plasticized by the liquid electrolyte, at least partly in contact with the separator layer (SG). The invention is particularly applicable to hybrid and/or electric vehicles or portable appliances.
