Abstract
Abstract
Porous silicon/metal composites have huge specific surface area, rich pore structure, tough framework system and low SEI film formation rate, and have great application prospects in the field of high-energy lithium batteries. Porous silicon/metal composites have abundant pore structure, which can greatly alleviate the volume effect of silicon during charging and discharging. The introduction of metal can increase the conduction rate and reduce the formation rate of SEI film. However, the development of a facile and rapid method to synthesize porous silicon/metal composites remains a challenge for current research. Based on the current research progress of porous silicon/metal composites and related literatures, in this paper, the preparation methods of porous silicon/metal composites in recent years are reviewed in detail, with a focus on their applications in the field of high-energy lithium batteries. Finally, the future development direction of porous silicon/metal composites is further prospected.
