Researchers report a low-cost, rechargeable, aqueous, nickel-hydrogen battery, which uses a nickel-based cathode and a nickel-molybdenum-cobalt electrocatalyst as hydrogen anode, resulting in an energy density of approximately 140 Wh per kg and rechargeability over 1,500 cycles; with an estimated cost of around $83 per kilowatt-hour, the battery might represent a low-cost option for long-term and large-scale energy storage, according to the authors.
