Cathode reaction of aluminum air battery7/23/2023 Metal-air batteries can be used as small power sources for portable electronic devices like electric cars.Some of the major companies present in the lithium-air battery market are Polyplus Battery Company, Mullen Technologies and Lithium Air Industries. Therefore lithium-air batteries can be a viable alternative to gasoline. The energy density of gasoline is about 13 kWh/kg and that of lithium-air batteries is about 12 kWh/kg. However, the practical power and life of lithium-air batteries need significant improvements before they can find a market niche.Ī major market driver for lithium-air batteries is the automotive sector. Theoretically, lithium-air batteries can be batteries with the highest possible specific energy. Lithium-air batteries – Lithium-air batteries use oxidation of lithium at the anode and reduction of oxygen at the cathode to produce electricity. Some of the major companies present in the zinc-air battery market are Phinergy, Primus Power and Eos Energy Storage. Small batteries are used for hearing aids, middling batteries are used in film cameras and large batteries are used for electric vehicle propulsion. These batteries have high energy densities and are relatively inexpensive to produce. Zinc-air batteries – Zinc-air batteries are powered by oxidizing zinc with oxygen from the air. Log 9 materials is an Indian startup making progress here. Phinergy, Fuji Pigment and Xinjiang are some of the major companies manufacturing aluminium-air batteries. However, it is possible to mechanically recharge the battery with new aluminium anodes made from recycling the hydrated aluminium oxide.Īpplications of aluminium-air batteries are restricted chiefly in military functions. They will no longer produce electricity once the aluminium of anode is consumed by its reaction with the oxygen of cathode immersed in an aqueous electrolyte to form hydrated aluminium oxide. This is because aluminium anodes are expensive and byproducts are costly to remove.Īluminium-air batteries are not rechargeable. They have one of the highest energy densities of all batteries but they are not widely used. QuantumScape, Volkswagen AG and Form Energy are some of the major companies developing iron-air battery technology.Īluminium-air batteries – Aluminium-air batteries produce electricity from the reaction of oxygen in the air with aluminium. Iron-air batteries could be used to store energy from photovoltaic panels, wind turbines and so on. Rapid sintering and pulverization of rust limits the ability to achieve a high number of cycles which results in diminished capacity. However, its limitation also comes from the materials used. Both of them are abundant, inexpensive and harmless. Iron-air batteries – Iron-air batteries are a promising technology.
