Pseudo-capacitive performance of titanate nanotubes as a supercapacitor electrode

Abstract

Layered titanate H₂Ti₃O₇ nanotubes were synthesized and firstly used as a supercapacitor electrode in a non-aqueous electrolyte. They exhibited the specific capacitances as high as 414 and 306 F g⁻¹ at 0.5 and 10 A g⁻¹, respectively, and 82% of the specific capacitance at the 10th cycle can be retained after 1000 cycles.
