Indian researchers have developed multiple promising zinc-air battery technologies, including low-cost electrolytes, novel catalysts, and mechanically rechargeable systems. Zinc-air batteries use zinc as the anode and oxygen from the air as the cathode reactant, offering high energy density — theoretically 3-5 times that of lithium-ion batteries — at a fraction of the cost. Unlike lithium-ion batteries, zinc is abundant, non-toxic, and inexpensive. These batteries are being explored for grid-scale energy storage, electric vehicles, and wearable electronics. The research aligns with India's energy storage target of 888 GWh by 2035-36.
