Title (EN) ELECTRODE ACTIVE MATERIAL FOR NONAQUEOUS SECONDARY BATTERY, AND METHOD FOR MANUFACTURING SAME
(FR) MATÉRIAU ACTIF D’ÉLECTRODE POUR ACCUMULATEUR NON AQUEUX, ET SON PROCÉDÉ DE FABRICATION
(JA) 非水系二次電池用電極活物質及びその製造方法
Abstract:
(EN) The purpose of one mode of the present disclosure is to provide an electrode active material capable of constituting a nonaqueous secondary battery with excellent output characteristics, and a method for manufacturing the electrode active material. A first mode is an electrode active material for a nonaqueous secondary battery that contains: alkali metal/transition metal composite oxide particles; graphene in which positive holes have been formed; and an anion. The electrode active material for a nonaqueous secondary battery is manufactured by obtaining graphene in which positive holes are formed by bringing a graphene raw material into contact with a two-coordinated boron cation, and bringing the graphene in which positive holes have been formed into contact with the alkali metal/transition metal composite oxide particles.
(FR) L’objet d’un mode selon la présente invention concerne un matériau actif d’électrode pouvant constituer un accumulateur non aqueux dont les caractéristiques de sortie sont excellentes, et un procédé de fabrication du matériau actif d’électrode. Un premier mode est un matériau actif d’électrode pour un accumulateur non aqueux qui contient : des particules d’oxyde composite de métaux alcalins/métaux de transition ; du graphène dans lequel des trous positifs ont été formés ; et un anion. Le matériau actif d’électrode pour un accumulateur non aqueux est fabriqué en obtenant du graphène dans lequel des trous positifs sont formés en mettant une matière première de graphène en contact avec un cation de bore à deux coordonnées, et en mettant le graphène dans lequel des trous positifs ont été formés en contact avec les particules d’oxyde composite de métaux alcalins/métaux de transition.
(JA) 本開示に係る一態様は、出力特性に優れる非水系二次電池を構成可能な電極活物質及びその製造方法を提供することを目的とする。 第一態様は、アルカリ金属‐遷移金属複合酸化物粒子と、正孔が形成されたグラフェンと、アニオンとを含む非水系二次電池用電極活物質である。 非水系二次電池用電極活物質は、グラフェン原料と2配位ホウ素カチオンとを接触させて正孔が形成されたグラフェンを得て、正孔が形成されたグラフェンとアルカリ金属-遷移金属複合酸化物粒子とを接触させて製造される。
