Abstract

An anode active material for a lithium-ion battery with greatly reduced recharging time includes SiO particles, graphite particles, and a carbon coating layer. The graphite particles and SiO particles are processed to form spherical SiO/graphite composite particles. A layer of carbon coating is applied to the surface of the SiO/graphite composite particle and the resulting anode active material resembles a pomegranate structure.
