Title (EN) LITHIUM ION SECONDARY BATTERY
(FR) BATTERIE SECONDAIRE AU LITHIUM-ION
(JA) リチウムイオン二次電池
Abstract:
(EN) The present invention provides a lithium ion secondary battery which is capable of improving cycle characteristics. This lithium ion secondary battery is provided with a positive electrode, a negative electrode, a separator positioned between the positive electrode and the negative electrode, and an electrolyte. The lithium ion secondary battery is characterized in that: the positive electrode includes a lithium vanadium compound; and the electrolyte includes a carboxylic acid ester.
(FR) La présente invention concerne une batterie secondaire au lithium-ion qui est capable d'améliorer les caractéristiques de cycle. La batterie secondaire au lithium comprend une électrode positive, une électrode négative, un séparateur qui est interposé entre l'électrode positive et l'électrode négative, et un électrolyte. La batterie secondaire au lithium-ion est caractérisée en ce que : l'électrode positive comprend un composé de lithium vanadium ; et l'électrolyte comprend un ester d'acide carboxylique.
(JA) 本発明は、サイクル特性を改善することが可能なリチウムイオン二次電池を提供する。 正極と、負極と、前記正極と前記負極の間に位置するセパレータと、電解液とを備えるリチウムイオン二次電池であって、前記正極がリチウムバナジウム化合物を含み、前記電解液がカルボン酸エステルを含むことを特徴とするリチウムイオン二次電池。
