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
