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

Green Car Congress

To maximize the benefit of the open structure, the researchers needed to use ions that fit; hydrated potassium ions proved to be a much better fit compared with other hydrated ions such as sodium and lithium. Potassium will just zoom in and zoom out, so you can have an extremely high-power battery. —Yi Cui. —Colin Wessells.

Can Flow Batteries Finally Beat Lithium?

Cars That Think

An example, she says, is the task of balancing energy flows in the power grid. Department of Energy’s Advanced Research Projects Agency–Energy (ARPA-E) to build a prototype 1 kilowatt-hour nanoelectrofuel battery. and an expert in flow batteries. Their energy density is as little as 10 percent that of lithium-ion batteries.
