Abstract

Seawater batteries with natural seawater as the electrolyte have drawn significant attention due to their advantages of low cost, environmental friendliness, and high theoretical energy density. Herein, an Mg-Ni seawater battery consisting of a magnesium anode and a carbon-loaded nickel foam cathode is developed, which exhibits excellent discharge performance with an ultra-high specific capacity of 1500 mAh g⁻¹ and discharge voltage kept above 1.28 V at the current density of 1 mA cm⁻² after stable discharge of 100 h. Moreover, the specific energy of the Mg-Ni seawater battery reaches a competitive value of 1950 Wh kg⁻¹.
