The new battery, which uses no metals or toxic materials, is intended for use in power plants where it can make the energy grid more resilient and efficient by creating large-scale means to store energy for use as needed.
"The batteries last for about 5,000 recharge cycles, giving them an estimated 15-year lifespan," said Sri Narayan, professor of chemistry at the University of Southern California Dornsife College of Letters, Arts and Sciences, and corresponding author of the study.
"Lithium ion batteries degrade after around 1,000 cycles, and cost 10 times more to manufacture," Narayan said.
Narayan collaborated with Surya Prakash, professor of chemistry and director of the USC Loker Hydrocarbon Research Institute, as well as USC's Bo Yang, Lena Hoober-Burkhardt and Fang Wang.
"Such organic flow batteries will be game-changers for grid electrical energy storage in terms of simplicity, cost, reliability and sustainability," said Prakash.
Solar panels can only generate power when the sun is shining, and wind turbines can only generate power when the wind blows. That inherent unreliability makes it difficult for power companies to rely on them to meet the demand of customers...
