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 relates to: a positive electrode for lithium ion secondary batteries, which contains a positive electrode active material and a positive electrode binder, and wherein the positive electrode active material contains lithium manganate having a spinel structure and the positive electrode binder contains at least a polyvinylidene fluoride (PVDF) and a resin having a sulfone bond; and a lithium ion secondary battery which comprises the positive electrode for lithium ion secondary batteries.
(FR) La présente invention concerne : une électrode positive pour batteries secondaires au lithium-ion, qui contient un matériau actif d'électrode positive et un liant d'électrode positive, et le matériau actif d'électrode positive contenant du manganate de lithium ayant une structure de spinelle et le liant d'électrode positive contenant au moins un polyfluorure de vinylidène (PVDF) et une résine ayant une liaison sulfone ; et une batterie secondaire au lithium-ion qui comprend l'électrode positive pour batteries secondaires au lithium-ion.
(JA)  本発明は、正極活物質と正極バインダーを含むリチウムイオン二次電池用正極であって、前記正極活物質が、スピネル構造を有するマンガン酸リチウムを含み、前記正極バインダーが、少なくともポリフッ化ビニリデン(PVDF)とスルホン結合を有する樹脂とを含む、リチウムイオン二次電池用正極、およびこれを含むリチウムイオン二次電池に関する。
