Potassium compounds are mainly used to produce fertilisers. Many potassium salts are of great importance in industrial applications, including nitrate, carbonate, chloride, bromide, cyanide and sulphate. Potassium carbonate is used, for example, in the manufacture of glass, and potassium hydroxide is used to make detergents and liquid soap. Potassium chloride is used in medicines and in brine. The impressive list has just been extended to include electric vehicle batteries.

In current practice, although it is produced in industrial quantities, it is also stored at huge cost, usually in bunker-like underground reinforced concrete sarcophagi. A company is now producing batteries from this hazardous waste to be used in all kinds of vehicles, cars, electric aircraft, etc.

The new energy storage combines two subgroups of battery development: solid-state electrolyte with an anode made entirely of silicon. The result is a highly energy-dense, cheap and durable battery that can be used as a grid storage device in the same way as in electric cars and the electric aircraft that are being developed.
