Lithium insertion compound of high voltage used as cathodic active mass in a lithium rechargeable electrochemical generator |
摘要 |
An insertion lithium compound is derived by substitution of dioxide of manganese lithia of spinel structure and has the formula (I) <??>LiMn2-(x+y)(MxM'y)4 (I) <??>x 0; <??>y 0; <??>X+Y 0.50 <??>M = Ni (nickel) or Co (cobalt); and <??>M' = Ti (titanium), Al (aluminium), Co (cobalt) or molybdenum (Mo). <??>Independent claims are also included for: <??>(a) fabrication of the insertion compound; <??>(b) an electrode for a lithium rechargeable electrochemical generator containing, as the active electrochemical material, the insertion compound; and <??>(c) a lithium based rechargeable electrochemical generator using such an electrode. |
