Nanosheet-Constructed Porous TiO2–B for Advanced Lithium Ion Batteries

Authors


Abstract

original image

Hierarchical porous TiO2–B with thin nanosheets is successfully synthesized. TiO2–B polymorph ensures fast insertion of Li-ion due to its pseudocapacitive mechanism. The thin nanosheet walls with porous structure allow exposure to electrolytes for facile ionic transport and interfacial reaction. The joint advantages endow this material with high reversible capacity, excellent cycling performance, and superior rate capability.
