Electrodeposition of hydrated vanadium pentoxide on nanoporous carbon cloth for hybrid energy storage

Date: Jan 11, 2018

Electrodeposition is a simple and effective method for the synthesis of disordered hydrated vanadium pentoxide (V2O5·nH2O). For the synthesis of energy storage electrodes with high power performance, electrodeposition of hydrated V2O5 inside the carbon micropores is particularly attractive to synergize electric-double layer formation and lithium ion intercalation. Here, we demonstrate that hydrated V2O5 can be effectively electrodeposited in carbon micropores of activated carbon cloth. Our study indicates that carbon pores larger than 1 nm are essential for the effective decoration of hydrated V2O5.
