Title (EN) NONAQUEOUS ELECTROLYTE BATTERY
(FR) ACCUMULATEUR À ÉLECTROLYTE NON AQUEUX
(JA) 非水電解液電池
Abstract:
(EN) Provided is a nonaqueous electrolyte battery which has good storage characteristics in a high temperature environment. A nonaqueous electrolyte battery according to the present invention comprises: an electrode body that is obtained by laminating a positive electrode and a negative electrode with a separator being interposed therebetween; and a nonaqueous electrolyte solution that contains a lithium salt and an organic solvent. This nonaqueous electrolyte battery is characterized in that: the positive electrode contains a lithium-containing layered nickel oxide that contains 50% by mole or more of Ni relative to Li; the negative electrode comprises a laminate that contains a metal base layer, which is not alloyed with Li, and an Al active layer that is bonded to one surface or both surfaces of the metal base layer; and an Li-Al alloy is formed on at least the surface side of the Al active layer.
(FR) L'invention concerne un accumulateur à électrolyte non aqueux qui présente de bonnes caractéristiques de stockage dans un environnement à température élevée. L'accumulateur à électrolyte non aqueux selon la présente invention comprend : un corps à électrodes qui est obtenu par stratification d'une électrode positive et d'une électrode négative, un séparateur étant intercalé entre elles ; une solution électrolytique non aqueuse contenant un sel de lithium et un solvant organique. Cet accumulateur à électrolyte non aqueux est caractérisé en ce que : l'électrode positive contient un oxyde de nickel stratifié contenant du lithium, qui contient au moins 50 % en moles de Ni par rapport à Li ; l'électrode négative comprend un stratifié qui contient une couche de base métallique, qui n'est pas alliée avec Li, et une couche active d'Al qui est liée à une surface ou aux deux surfaces de la couche de base métallique ; un alliage Li-Al est formé sur au moins le côté surface de la couche active d'Al.
(JA) 高温環境下での貯蔵特性が良好な非水電解液電池を提供する。 本発明の非水電解液電池では、正極と負極とがセパレータを介して重ねられた電極体と、リチウム塩および有機溶媒を含有する非水電解液とを有しており、前記正極は、Liに対してNiを50モル%以上含むリチウム含有ニッケル層状酸化物を含有し、前記負極は、Liと合金化しない金属基材層と、前記金属基材層の片面または両面に接合されたAl活性層とを含有する積層体を有し、前記Al活性層の少なくとも表面側には、Li-Al合金が形成されていることを特徴とするものである。
