col (PEG)-derived carbon have been prepared by using only PEG reagent as thecarbon source and dispersant and just involving ball-milling and carbonization processes. This preparationstrategy shows relatively green and simple characteristics. More importantly, thus PEG-derived carbon coatingeffectively mitigates the problems of large volumetric expansions and poor conductivity faced by Si anodes.Consequently, B-Si NPs@C-2 with the optimized carbon coating shows superior lithium storage performance,with 1055.1 mAh g 1 after 300 cycles at 400 mA g 1 and 733.3 mAh g 1 after 1100 cycles at 1000 mA g 1.Taking into account the advantages of the relatively green and simple preparation process and the superb per-formance of B-Si NPs@C-2, this study might pave the way towards a green and more sustainable development ofthe advanced Si/C anodes for lithium-ion batteri
