A porous Si/Ag composite material derived by waste rice husk was synthesized via magnesiothermic reduction-silver mirror reaction. The structure, surface morphology and lithium storage performance were investigated. The results show that the particle sizes of obtained biomass silicon material with a porous structure are 10-20 nm, and the cycle performance, rate performance and specific capacity of the electrode all are improved by recombining silver nanoparticles. The capacity of electrode with the silver particles can retain 750.4 mA·h/g after 50 cycles, which is twice greater than that of graphite, and it is 370.2 mA·h/g greater than that of pure biomass silicon electrode. The biomass Si/Ag electrode exhibits the specific capacity of 618.3 mA·h/g at current density of 800 mA/g, which is higher than that of biomass silicon (380.2 mA·h/g), due to the higher conductivity of Si/Ag nanomaterial and excellent property of electrode/electrolyte interface.
