Title (EN) LITHIUM SECONDARY BATTERY OF ELECTROLYTE CONTAINING AMMONIUM COMPOUNDS
(FR) BATTERIE SECONDAIRE AU LITHIUM DE COMPOSES D'AMMONIUM CONTENANT UN ELECTROLYTE
Abstract: front page image
(EN)Disclosed is a lithium secondary battery using a cathode containing a lithium- containing transition metal oxide and an anode containing graphitized carbon, characterized in that an ammonium compound capable of providing ammonium ions is added to a non-aqueous electrolyte. Therefore, the present invention provides a lithium secondary battery having improved high-temperature performance by reducing decreases of residual capacity and recovery capacity resulting from high-temperature storage of the battery, via addition of such an ammonium compound.
(FR)L'invention concerne une batterie secondaire au lithium utilisant une cathode contenant un oxyde métallique de transition contenant du lithium et une anode contenant un carbone graphité. Le composé d'ammonium, qui peut fournir des ions d'ammonium, est ajouté à un électrolyte non aqueux. L'invention concerne donc une batterie secondaire au lithium présentant une performance améliorée à température élevée, les baisses de capacité résiduelle et de capacité de récupération étant réduites du fait du stockage à température élevée de la batterie, grâce à l'adjonction d'un tel composé d'ammonium.
