Title (EN) NONAQUEOUS ELECTROLYTE SECONDARY BATTERY
(FR) BATTERIE SECONDAIRE À ÉLECTROLYTE NON AQUEUX
(JA) 非水電解質二次電池
Abstract:
(EN) The purpose of the present invention is to provide a nonaqueous electrolyte secondary battery having a combination of a negative electrode comprising a lithium-titanium composite oxide and a carbon material, and a positive electrode comprising a lithium-containing transition metal oxide, wherein an increase in the IV resistance of the battery can be suppressed. This nonaqueous electrolyte secondary battery is provided with a positive electrode, a negative electrode, a separator positioned between the positive electrode and negative electrode, and a nonaqueous electrolyte. The positive electrode includes elemental tungsten and a lithium-containing transition metal oxide in which the proportion of Ni with respect to the total moles of elemental metals excluding Li is not less than 30 mol%. The negative electrode includes a carbon material and a lithium-titanium composite oxide. The nonaqueous electrolyte includes a substance reduced on the negative electrode at a potential of 0.5 to 1.5 V (vs. Li/Li+).
(FR) La présente invention vise à proposer une batterie secondaire à électrolyte non aqueux ayant une combinaison d'une électrode négative comprenant un oxyde composite de lithium-titane et une matière carbonée, et une électrode positive comprenant un oxyde métallique de transition contenant du lithium, une augmentation de la résistance IV de la batterie pouvant être supprimée. La batterie secondaire à électrolyte non aqueux selon la présente invention comprend une électrode positive, une électrode négative, un séparateur qui est interposé entre l'électrode positive et l'électrode négative, et un électrolyte non aqueux. L'électrode positive comprend du tungstène élémentaire et un oxyde métallique de transition contenant du lithium dans lequel la proportion de Ni par rapport au nombre total de moles de métaux élémentaires à l'exception de Li n'est pas inférieure à 30 % en moles. L'électrode négative comprend une matière carbonée et un oxyde composite de lithium-titane. L'électrolyte non aqueux comprend une substance réduite sur l'électrode négative à un potentiel de 0,5 à 1,5 V (par rapport à Li/Li+).
