Stationary energy storage systems that can operate for many cycles, at high power, with high round-trip energy efficiency, and at low cost are required. Because the ions can move so freely, the electrode’s cycle of charging and discharging is extremely fast. Cost is a greater concern. —Colin Wessells.

Sodium-ion batteries (Na-ion, NIBs) are seen as an alternative to lithium-ion batteries for large-scale applications due to their lower cost and abundant supply of sodium. However, low capacity and poor rate capability of existing anodes have been major obstacles to the commercialization of NIBs. Lev and Dr. Denis Y.W.

This process is reversed upon charging. It was the most difficult chemistry” to make work but had potential benefits due to calcium’s low cost as well as its inherent high voltage as a negative electrode. It was the seeming impossibility of making calcium work in a liquid battery that attracted Ouchi to the problem, he says. “It
