Title (EN) NON-AQUEOUS ELECTROLYTE SECONDARY CELL
(FR) ACCUMULATEUR ELECTROLYTIQUE NON AQUEUX
Abstract: front page image
(EN) A non-aqueous electrolyte secondary cell which comprises a positive electrode containing a lithium-containing oxide, a negative electrode containing a material capable of occluding and releasing lithium, and a non-aqueous electrolyte containing at least one acyclic ester, wherein the non-aqueous electrolyte further contains an agent improving the resistance to oxidation, such as triphenylmethane or tetraphenylmethane. The secondary cell exhibits excellent storage stability at a high temperature.
(FR) L'invention concerne un accumulateur électrolytique non aqueux comprenant une électrode positive qui contient un oxyde contenant du lithium; une électrode négative qui contient une matière capable de retenir et de libérer le lithium; et un électrolyte non aqueux contenant au moins un ester acyclique, l'électrolyte non aqueux contenant en outre un agent qui améliore la résistance à l'oxydation tel que le triphénylméthane ou le tétraphénylméthane. L'accumulateur selon l'invention possède une excellente stabilité au stockage à haute température.
