Abstract:Silicon‐based materials are among the highly promising anode candidates for Li‐ion batteries owing to their excellent theoretical energy density. However, the huge volume variation makes the application of silicon anode in lithium‐ion batteries be full of challenge. Herein, high‐performance Si@C@rGO composites anode for lithium‐ion batteries are successfully prepared by graphene oxide (GO) uniformly encapsulating resorcinol‐formaldehyde resin (RF) coated silicon nanoparticles. The RF‐derived carbon layer can p… Show more
Si-based electrodes are considered as the most promising anode for next generation lithium-ion batteries because of their ultrahigh theoretical capacity. However, the huge volume change of silicon during repeated alloying...
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
