A new generation of organic flow batteries shows promise for energy storage
The EU-funded BALIHT project is designing new redox organic flow batteries that can work at temperatures of up to 80 °C. Researchers claim that the batteries will offer longer duration, higher power and a 20 % higher energy efficiency compared to other organic battery types. The new battery will be based on low-cost, abundant organic molecules that are easily dissolved in water, electrolytes comprising lignin, thin non-fluorinated membranes and carbon electrodes. Redox organic flow batteries are one of the most promising approaches to sustaining a grid powered by the sun and wind, improving grid flexibility and stability and providing high-performance charge points for electric cars.
