Title (EN) LITHIUM ION SECONDARY BATTERY, METHOD FOR PRODUCING SAME, AND METHOD FOR EVALUATING SAME
(FR) BATTERIE SECONDAIRE AU LITHIUM-ION, SON PROCÉDÉ DE PRODUCTION ET PROCÉDÉ D'ÉVALUATION DE CETTE DERNIÈRE
(JA) リチウムイオン二次電池、その製造方法およびその評価方法
Abstract: front page image
(EN)Provided is a lithium ion secondary battery which includes: a positive electrode which contains, as the positive electrode active substance, a compound oxide that contains lithium and nickel and that has a lamellar crystal structure; a negative electrode which contains a graphite material as the negative electrode active substance; and an electrolyte. The lithium ion secondary battery has a Warburg coefficient (σ­0) per charge capacity as found by the alternating impedance method of 0.005 or less.
(FR)L'invention concerne une batterie secondaire au lithium-ion qui comprend : une électrode positive qui contient, en tant que substance active d'électrode positive, un oxyde de composé qui contient du lithium et du nickel et qui a une structure cristalline lamellaire ; une électrode négative qui contient un matériau de graphite en tant que substance active d'électrode négative ; et un électrolyte. La batterie secondaire au lithium-ion possède un coefficient de Warburg (σ­0) par capacité de charge tel que trouvé par le procédé d'impédance alternative de 0 005 ou moins.
(JA)層状結晶構造を有するリチウムニッケル含有複合酸化物を正極活物質として含む正極と、黒鉛質材料を負極活物質として含む負極と、電解液を含むリチウムイオン二次電池であって、交流インピーダンス法で求めた充電容量当たりのワールブルグ係数(σ)が0.005以下である、リチウムイオン二次電池。
