摘要: Abstract Porous carbon supported nanotube@CoP (PC@CNT@CoP) with 3D polyhedron structure has been prepared by a modified phosphorization approach for lithium ion batteries enhanced performance. As result, PC@CNT@CoP electrode exhibits high initial discharge capacity of 2410.9 mAh⋅g−1 at current density 0.1 A⋅g−1 in the first circle, and reversible charge 1187.5 mAh⋅g−1. After 50 circles, is 951.6 mAh⋅g−1, indicating 85.1% capacitance remaining. Even increased to 5 A⋅g−1, still possesses 155.4 mAh⋅g−1, illustrating excellent rate capability.
