Three-dimensional hierarchical ternary aerogels of ultrafine TiO2 nanoparticles@porous carbon nanofibers-reduced graphene oxide for high-performance lithium-ion capacitors

A novel three-dimensional hierarchical ternary aerogel of TiO2 [email protected] carbon nanofibers-reduced graphene oxide (TiO2@PCNF-GA) was designed as an advanced anode for lithium-ion capacitors. TiO2@PCNFs were first fabricated by electrospinning assisted by carbonization and a post-etching process, and then assembled into reduced graphene oxide aerogels (GAs) to obtain the TiO2@PCNF-GAs. The uniform distribution of the ultrafine TiO2...
