Metal-organic-framework-derived CoP nanoparticles-embedded into carbon nanocages for high-performance lithium-ion battery

摘要

CoP nanoparticles embedded into N-doped carbon nanotube nanocages are synthesized by the calcination of the core-shell metal organic framework and subsequent vapour-phase phosphorization. The asprepared composite shows an outstanding electrochemical property (1107 mA h g(-1) at 0.05 A g(-1)) and robust life. The outstanding properties are ascribed to the hollow structure and N-doped carbon framework. (C) 2021 Elsevier B.V. All rights reserved.
