IndianOil refuses to wake up with his hand in the pot. Invests in metal-air batteries.

Market analysts agree: at the moment there is no segment that would develop faster than the market for electrical cells. Meanwhile, the fossil fuel market is deteriorating. This is why the Indian state-owned petrochemical company IndianOil has decided to take it one step further.

Plant for the production of metal-air accumulators instead of crude oil. Of course in the future

IndianOil announced that it will join forces with the Israeli company Phinergy, which designs aluminum-air and zinc-air (Al-air, Zn-air) cells. The Indian company chose this technology because the country has reserves of aluminum and a well-developed industry for the processing of this metal.

IndianOil has announced a small stake in Phinergy, but the next step will be a collaboration that will lead to the construction of an aluminum-air cell plant with a channel to supply, service and repair this type of battery (source).

Air-aluminum cells disposableafter the energy is exhausted, all contents must be replaced. But they have an advantage: while modern lithium-ion cells currently have an energy density of around 0,3 kWh/kg mass, aluminum-air cells start at 1,3 kWh/kg and are theoretically around 8 kWh/kg ! IndianOil explicitly states that metal-to-air technology can play a supporting role for lithium-ion batteries – and that makes a lot of sense.

The Tesla Model 3 battery with a range of 500 kilometers weighs less than 0,5 tons. The current version of the aluminum air cells developed by Phinergy will give the same range at less than 125kg. With a 25 kg container, we would have a spare 100 kilometers "just in case."

The only drawback would be the need to replace cartridges after such emergency use:
