New nanoparticle copper compound cathode could enable low-cost, long-life and high-power potassium-ion batteries for grid storage

Green Car Congress

Yi Cui has developed nanoparticle copper hexacyanoferrate (CuHCF) battery cathode materials that demonstrate long cycle life and high power for use in grid storage applications. Short-term transients, including those related to wind and solar sources, present challenges to the electrical grid. Cost is a greater concern.

Rechargeable membrane-less hydrogen bromine flow battery shows high power density

Green Car Congress

That is about three times as much power per square centimeter as other membrane-less system—a power density that is an order of magnitude higher than that of many lithium-ion batteries and other commercial and experimental energy-storage systems. One such permutation is the hydrogen bromine flow battery.
