The cycling stability and capacity of Li-ion rechargeable batteries are improved, particularly in an elevated temperature range of about 55 DEG C., by the use of lithium aluminum manganese oxy-fluoride electrode components having the general formula, Li1+xAlyMn2-x-yO4-zFz, where x</=0.4, 0.1</=y</=0.3, and 0.05</=z</=0.5. |
