Abstract
Abstract In this paper we report a novel Mn 3 O 4 electrode doped with nano-NaBiO 3 . It is demonstrated that doping with nano-NaBiO 3 alters the electrochemical inertia of Mn 3 O 4 , converting it into a rechargeable secondary alkaline cathode material that exhibits highly efficient charge/discharge properties. While a pure Mn 3 O 4 electrode can barely maintain a single charge and discharge cycle, the cycling capacity of the Mn 3 O 4 electrode doped with nano-NaBiO 3 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 Mn 3 O 4 cathode could possibly shorten to as little as 30 min.
