Synthesis of RuO2/V2O5 Electrode Materials Suitable for a Positive Electrode in Lithium-ion Secondary Batteries
This project involves the preparation of RuO2/V2O5 nanocomposite for a positive electrode was realized via solvothermal method. We confirmed its characteristics and electrochemical performances. Our results showed that RuO2/V2O5 nanocomposite has doubled capacity and long reversibility compared with pristine V2O5 and RuO2. RuO2/V2O5 nanocomposites were synthesized for a lithium-ion secondary battery, employing a simple chemical route and high temperature annealing process to overcome drawbacks of each material. RuO2/V2O5 nanocomposites studied at both different heat treatment and different RuCl3 concentrations conditions. Electrochemical properties of RuO2/V2O5 nanocomposite shows heat treatment dependence. Different concentrations of RuCl3 were used to obtain better electrochemical properties in RuO2/V2O5 nanocomposites. When V2O5 and RuO2 were combined, it shows synergy effect compare with pristine materials. This work reported a facile synthetic route suitable for large scale positive active electrode material production.
