Mn3O4 doped with nano-NaBiO3: A high capacity cathode material for alkaline secondary batteries
چکیده انگلیسی

In this paper we report a novel Mn3O4 electrode doped with nano-NaBiO3. It is demonstrated that doping with nano-NaBiO3 alters the electrochemical inertia of Mn3O4, converting it into a rechargeable secondary alkaline cathode material that exhibits highly efficient charge/discharge properties. While a pure Mn3O4 electrode can barely maintain a single charge and discharge cycle, the cycling capacity of the Mn3O4 electrode doped with nano-NaBiO3 can reach and become stable at 372 mAh g−1 under 60 mA g−1. The doped cathode can also maintain a cycling capacity of 261 mAh g−1 while holding a 95.3% reversible capacity after 60 cycles at a high rate of 500 mA g−1. Moreover, the experimental results indicate that charging time for an alkaline battery using doped Mn3O4 cathode could possibly shorten to as little as 30 min.
