Engineers are nothing if not creative. Significant research is going into improved ways of storing electricity, including alternatives to the currently dominant lithium-ion battery-cell chemistry in electric cars. That includes using supercapacitors to substitute for storage batteries in some circumstances. DON’T MISS: Batteries from junkyard… …read more
