CATHODE MATERIAL AND LITHIUM ION BATTERY THEREFROM |
摘要 |
A new high performing lithium ion cell having new carbon based anode and new dual doped layered cathode materials. The anode is a self standing carbon fibrous material and the cathode is a dual doped Lithium cobalt oxide of general formula LiMxNyCo1-x-yO2 (0.01≦̸x, y≦̸0.2) wherein M is a divalent alkaline earth metal cation and N is a divalent transition metal cation. Lithium ion cells of 2016 coin cells were assembled using the above materials deliver specific capacity of 60-85 mAhg−1 at 1 C rate and exhibit excellent cycling stability of 90-95% even after 200 cycles when cycled between 2.9-4.1V. |
