Abstract

A novel porous Si/C composite is designed and synthesized to improve coulombic efficiency and cycle performance. Reversible capacity is more than 850 mA h gāˆ’1 with high coulombic efficiency of 99.5% in 200 cycles without destruction of the porous structure, aggregation of nanosilicon particles and swelling of the SEI film.
