Abstract

An aqueous rechargeable battery system is assembled by using metallic zinc and Na_0.95MnO₂ as the negative and positive electrodes, respectively. It is cheap and environmentally friendly, and its energy density is 78 Wh kg⁻¹. Its cycling performance is very good with only 8% capacity loss after 1000 cycles at 4 C between 1 and 2 V.
