Title (EN) SECONDARY BATTERY
(FR) BATTERIE SECONDAIRE
(JA) 二次電池
Abstract: front page image
(EN)A negative-electrode active material layer (243) of a lithium ion secondary battery (100) is provided with a portion (243a) which faces a positive-electrode active material layer (223), and portions (243b1, 243b2) which do not face the positive-electrode active material layer (223). Among these portions, the portion (243a) which faces the positive-electrode active material layer (223) has an equilibrium potential (Ea) higher than the equilibrium potential (Eb) of the portions (243b1, 243b2) which do not face the positive-electrode active material layer (223) (Ea>Eb).
(FR)Selon l'invention, une couche de matériau actif d'électrode négative (243) d'une batterie secondaire au lithium-ion (100) comporte une partie (243a) qui fait face à une couche de matériau actif d'électrode positive (223), et des parties (243b1, 243b2) qui ne font pas face à la couche de matériau actif d'électrode positive (223). Parmi ces parties, la partie (243a) qui fait face à la couche de matériau actif d'électrode positive (223) a un potentiel d'équilibre (Ea) supérieur au potentiel d'équilibre (Eb) des parties (243b1, 243b2) qui ne font pas face à la couche de matériau actif d'électrode positive (223) (Ea>Eb).
(JA) リチウムイオン二次電池100の負極活物質層243は、正極活物質層223に対向している部位243aと、正極活物質層223に対向していない部位243b1、243b2とを備えている。このうち、正極活物質層223に対向している部位243aの平衡電位Eaは、正極活物質層223に対向していない部位243b1、243b2の平衡電位Ebよりも高い(Ea>Eb)。
