Description
Tao Cheng and co-authors wrote a study from 2026 on making a kind of flow battery work well in the cold. Flow batteries store energy in tanks of liquid and suit large-scale storage. The zinc and bromine type tends to fail at low heat, since its liquid can split apart or move ions too slowly. The team looked at which helper ion in the liquid does the job best.
They tried an ammonium ion in place of the usual potassium ion. The new ion kept the liquid from splitting in the cold and let ions move faster at the same time. It also helped the battery last longer by keeping a key part dissolved. Cells with the new liquid ran for thousands of cycles at room heat. They also ran well at twenty degrees below zero, a hard test for this kind of battery.
