A novel approach to synthesize micrometer-sized porous silicon as a high performance anode for lithium-ion batteries

The table of contents entry: Microsphere silicon with unique structure can be prepared by a novel approach starting from SiO2 nanoparticles. The obtained micro-sized silicon exhibits a tap density close to that of bulk Si particles. Well controlled void space and a highly graphitic carbon coating on the designed silicon particles enable good stability of the structure and low overall resistance, thus resulting in a Si-based anode with high capacity, enhanced cycling performance and high rate capability.203
