Sugar additive plays a surprise role, boosting flow battery capacity and longevity for this grid energy resilience design RICHLAND, Wash. — A common food and medicine additive has shown it can boost the capacity and longevity of a next-generation flow battery design in a record-setting experiment. The California flow. . Researchers prepare an experimental flow battery electrolyte that has shown long life in the laboratory setting. This decoupling of power and energy capacity allows for independent scaling – you can increase storage duration without increasing power output, and vice versa. A commonplace chemical used in water treatment facilities has been repurposed for large-scale energy storage in a new battery design by researchers at the Department of Energy's Pacific Northwest National. .
