Phosphorus is an ideal anode material for high-rate lithium-ion batteries due to its high theoretical specific capacity and moderate operating potential. However, phosphorus undergoes tremendous volume expansion low electrical conductivity during lithium storage, affecting actual storage performance. The formation of P–C bonds effective strategy inhibit the maintain stable contact between current collector. Herein, strength metal nanoparticles, such as molybdenum are introduced into ball milling process reinforce bonding enhance As a result, BP/Mo/CNTs provides 984 mAh g–1 at 8.0 A retention 90.3% after 300 cycles 0.5 g–1. To demonstrate universality this method, BP/W/CNTs nanocomposites were prepared by tungsten-assisted milling. This facile practical approach abundant covalent improve electrochemical performance composites.
