Abstract:In this work, we synthesized highly porous 3D sponge‐like mesoporous (MP)‐Si@C composites using mass‐scalable method. The optimized MP−Si@C 1 composite electrode, provided a reversible capacity of 1887 mAh g−1 after 100 discharge−charge cycles with capacity retention of 83 % at the rate of 0.1 C. At high C‐rate the MP−Si@C 1 anode provided reversible capacity of 910 mAh g−1 after 1000 cycles. The MP−Si@C 1/LCO full cell provide a discharge capacity of 1515 mAh g−1 and it works well for 100 cycles. This outstan… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
