![]() ![]() Moreover, this battery obtained an initial discharge capacity of 125.1 mA h g −1 at a current density of 100 mA g −1 and cycling stability with 86% capacity retention after 100 cycles. Moreover, using VO 2 nanorods, generated via a one-step hydrothermal process, as the anode material revealed good rate properties. This electrode exhibited excellent cycle performance in an Mg(NO 3) 2 electrolyte, and the corresponding retention was 89.7% after 300 cycles. In this work, we have reported a Ni-doped magnesium manganese oxide as the cathode via a conventional hydrothermal method, which can help improve conductivity and solve defects derived from pure manganese oxide with nickel doping. ![]() ![]() However, optimized electrodes are the key to realize their advantages. Aqueous magnesium-ion batteries feature good safety and high energy density and represent promising energy storage systems. ![]()
