Abstract

MnO₂-carbon composites with various Mn/C ratios were prepared by precipitation method. The composites were cast onto Ni foam to be evaluated as cathodes of Li-air battery. Charge-discharge tests were carried out by using a Swagelok type cell in an 1 M LiPF₆ in a mixture of propylene carbonate (PC), ethylene carbonate (EC) and diethyl carbonate (DEC) (1:1:2 weight ratio). The influence of Mn/C ratio on both capacity and charge/discharge behavior was investigated. The cycle performance of Li/O₂ batteries was strongly dependent on Mn/C ratio. With increasing amount of MnO₂, the cycle performance of Li/O₂ batteries improved. The influence of electrolyte amount was also investigated, and the best cycle performance was achieved when 90 μL of electrolyte was used.
