Abstract

Si/C microsphere anodes with well-designed structures were successfully synthesized via the polymerization-induced colloid aggregation (PICA) method. The voids and void-holes in the carbon framework provide the direct and elastic buffer space for volume expansion of Si nanoparticles, respectively. This anode exhibits an outstanding structural integrity and enhanced cycling stability.
