Title (EN) ELECTRODE MATERIAL, CELL, AND METHOD FOR PRODUCING ELECTRODE MATERIAL
(FR) MATÉRIAU D'ÉLECTRODE, PILE ET PROCÉDÉ DE PRODUCTION D'UN MATÉRIAU D'ÉLECTRODE
(JA) 電極材料、電池、及び電極材料の製造方法
Abstract: front page image
(EN)A positive electrode material (21) or a negative electrode material (31), wherein functional groups on the surfaces of particles that contain a positive electrode active substance or a negative electrode active substance are protected by -Si-tBu groups, thereby suppressing decomposition of the electrolyte solution, and suppressing decline in discharge capacity.
(FR)L'invention concerne un matériau d'électrode positive (21) ou un matériau d'électrode négative (31), des groupes fonctionnels présents sur les surfaces de particules contenant une substance active d'électrode positive ou une substance active d'électrode négative étant protégés par des groupes -Si-tBu pour ainsi éviter toute décomposition de la solution d'électrolyte et éviter toute diminution de la capacité de décharge.
(JA) 正極の電極材料21又は負極の電極材料31において、正極活物質又は負極活物質を含む粒子表面の官能基を、‐Si‐tBu基で保護することによって、電解液の分解が抑制され、放電容量の低下が抑制される。
