Ti3C2Tx-foam as free-standing electrode for supercapacitor with improved electrochemical performance
Source abstract
Abstract
Abstract To prevent restacking of the Ti 3 C 2 T x layers, the Ti 3 C 2 T x -foam has been successfully synthesized through thermal treatment of Ti 3 C 2 T x -film with the hydrazine monohydrate. The interconnected porous structure of Ti 3 C 2 T x -foam could effectively reduce the restacking of the Ti 3 C 2 T x sheets and shorten the diffusion path of ions and accelerate the intercalation/de-intercalation of ions. The Ti 3 C 2 T x -foam-80 used as free-standing electrode achieves a high areal capacitance of 271.2 mF/cm 2 (122.7 F/g) at a scan rate of 5 mV/s in 1 M KOH electrolyte. It also exhibited a high capability rate of 65.5% from 5 mV/s to 100 mV/s and good cycle life with 88.7% retention of its initial after 10,000 cycles at a scan rate of 50 mV/s.
