摘要: Abstract The Si–AB 5 (MmNi 3.6 Co 0.7 Al 0.3 Mn 0.4 alloy) composites with a high tap density as anode materials for lithium-ion batteries were synthesized by ball-milling. Si nanoparticles are distributed homogeneously on the surface of AB matrix. electrochemical performance function content was investigated. It is demonstrated that composite delivers larger reversible capacity and better cycle ability because inactive alloy can accommodate large volume changes during cycling. In particular, containing 20 wt% 2.8 g/cm 3 obtained after ball-milling 11 h exhibits an initial maximum (charge) 370 385 mAh/g. retention be achieved 50 cycles in potential range from 0.02 to 1.5 V.
