Summary:种新型高性能锂离子电池，其具有新的碳基阳极和新的双掺杂层状阴极材料。该阳极是自立式碳纤维材料，并且该阴极是通式为LiMNCoO(0.01≤x,y≤0.2)的双掺杂锂钴氧化物，其中M是二价碱土金属阳离子且N是二价过渡金属阳离子。使用上述材料组装的2016硬币电池的锂离子电池在1C倍率下释放60-85mAhg的比容量，并且即使在2.9-4.1V之间循环200次循环之后仍显示出90-95%的优秀循环稳定性。 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.
