Title (EN) TITANIUM- AND/OR GERMANIUM-SUBSTITUTED LITHIUM MANGANESE COMPOSITE OXIDE AND METHOD FOR PRODUCING SAME
(FR) OXYDE COMPOSITE DE LITHIUM MANGANÈSE SUBSTITUÉ PAR DU TITANE ET/OU DU GERMANIUM ET SON PROCÉDÉ DE PRODUCTION

Abstract:
(EN) A lithium manganese composite oxide which is represented by general formula (1) Li1+x(M1yM2zMn1-y-z)1-xO2 (wherein M1 represents Fe and/or Ni; M2 represents Ti and/or Ge; and x, y and Z satisfy 0 < x < 1/3, 0 ≤ y ≤ 0.4 and 0 < z ≤ 0.3) and contains a crystal phase having a monoclinic layered rock salt structure or a hexagonal layered rock salt structure is a novel material that has few resource constraints and uses low-cost elements, while achieving high capacity and high discharge voltage and exhibiting excellent long-term cycle characteristics for maintaining the similarity of the shapes of charge/discharge curves during charge/discharge cycles if used for a positive electrode material for lithium ion secondary batteries.
(FR) Un oxyde composite de lithium manganèse représenté par la formule générale (1) Li1+x(M1 yM2 zMn1-y-z)1-xO2 (dans laquelle M1 représente Fe et/ou Ni; M2 représente Ti et/ou Ge; et x, y et z satisfont 0 < x < 1/3, 0 ≤ y ≤ 0,4 et 0 < z ≤ 0,3) et contenant une phase cristalline ayant une structure de sel gemme stratifiée monoclinique ou une structure de sel gemme stratifiée hexagonale, est un nouveau matériau qui a peu de contraintes de ressources et utilise des éléments à faible coût, tout en obtenant une haute capacité et une haute tension de décharge et présentant d'excellentes caractéristiques de cycle à long terme pour maintenir la similarité des formes des courbes de charge/décharge pendant les cycles de charge/décharge s'il est utilisé pour un matériau d'électrode positive pour batteries secondaires au lithium-ion.
(JA) 一般式(1): Li1+x(M1yM2zMn1-y-z)1-xO2 (1) [式中、M1はFe及び/又はNiを示す。M2はTi及び/又はGeを示す。x、y及びzは、0
