Abstract

Nowadays pseudocapacitors are gaining more attention because its ultra-high charging speed. However, the capacitance and conductivity of traditional pseudocapcitors remains relatively low. In this research, the method of doping NiO into Nb2O5 to improve the performance of hybrid pseudocapacitor with T-Nb2O5 cathode is studied more, which is to optimize the performance in certain doping level, voltage range, and temperature. The target improvements is to both preserve the high energy density of Nb2O5 pseudocapacitor and increase the power density by increasing its conductivity.
