Stable form of LiMnO2 as cathode in lithium cell |
| 摘要 |
The invention disclosed relates to a new method of forming spinel-related lambda -Li2-xMn2O4, wherein 0</=x</=2, solely by electrochemical means with air-stable orthorhombic LiMnO2 as the starting material. This spinel-related material is hydroscopic, metastable and is typically made by chemical means, followed by electrochemical conversion of spinel-type LiMn2O4. Also disclosed are new secondary lithium ion electrochemical cells employing as initial active cathode material a compound of formula LiMnO2, having a specific orthorhombic crystal structure.
