Double-buffer silicon-carbon anode material by a dynamic self-assembly process for lithium-ion batteries

The volume expansion of the silicon (Si) anode material is still a main bottle-neck problem limiting its battery application. Effective structure design needs to be studied continuously, meanwhile the process feasibility also cannot be ignored. Herein, a novel yet simple method to prepare double-buffer structure hybrids with a multilevel porous self-assembly structure induced by hydrogen bonding employing spray-drying methods is reported. The...
