Highly porous Li4Ti5O12/C nanofibers for ultrafast electrochemical energy storage

Nanopores in electrospun nanofibers have been rationally designed to generate highly porous Li4Ti5O12/C nanofibers that exibit high capacity, excellent cyclability, and super-high rate capability in lithium-ion batteries and hybrid supercapacitors. The as-formed fibrous Li4Ti5O12/C nanocomposite with high porosity offers a great potential for advanced ultrafast electrochemical energy storage devices.522
