Insertion compound able to be used as cathodic active material of a lithium rechargeable electrochemical cell |
| 摘要 |
A compound for use as active material of a positive electrode of a lithium-ion cell. This compound has an average discharge voltage above 4.5V in relation to the Li+/Li couple of approximately 4.7V. The compound includes: a) a spinel-type crystalline phase of formula LiaNiII0.5−xMnIII2xMnIV1.5−x−yMyO4 in which elements Ti and Al, or a mixture of these; 0.8<a<1.3; 0<x≰0.15; 0<y≰0.15; b) a cubic crystalline phase of formula Li1−tNi1+tO in which 0≰t≰1; and c) a rhomboedric crystalline phase of formula Li1−ZNi1+zO2 in which 0≰z≰1.
