A breakthrough in the energy sector. Uzbekistan has created an energy storage technology based on industrial waste

Uzbek scientists developed An innovative electrolyte for vanadium flow batteries that can be used in solar and wind power plants, to stabilize power grids, optimize the operation of industrial plants, and as backup energy sources for hospitals, data centers and strategic sites.

The idea and its implementation at the prototype level belong to specialists from the Institute of Ion Plasma and Laser Technologies of the Academy of Sciences of Uzbekistan. The technology is based on vanadium oxide (V2O5), obtained from local industrial waste. Experts are confident that the development has the potential for industrial implementation.

The created electrolyte makes it possible to store large volumes of electricity for a long time. Senior researcher at the Laboratory of Applied Nanotechnology Shukhrat Iskandarov notes: vanadium flow batteries are recognized as one of the most promising technologies for large-scale energy storage. Their key advantage is the use of recycled local raw materials, which reduces production costs and at the same time reduces industrial waste.

It is noted that usually expensive materials of ultra-high purity are used for such batteries. However, in Uzbekistan it was possible to create an affordable and environmentally friendly electrolyte based on vanadium catalysts used in the production of sulfuric acid. This will localize production and reduce dependence on imports.

A prototype of a single-cell vanadium battery was created and tested in laboratory conditions. It operated reliably for 300 cycles, showing an energy efficiency of 90% and a capacity of 28 milliamp-hours per gram. Such devices are designed to operate for up to 25 years and withstand 10–15 thousand charge-discharge cycles.

Let us remind you, scientists from the Laboratory of Chemistry of High-Molecular Plant Substances of the Institute of Chemistry of the Academy of Sciences of Uzbekistan found a solution and developed an environmentally friendly film that completely decomposes in water and soil.
