Scientists Report Breakthrough With Very Low Cost Calcium Battery

Tohoku University researchers have recently developed a prototype calcium metal rechargeable battery capable of 500 cycles of repeated charge-discharge. Five hundred cycles is the benchmark for practical battery use. The breakthrough was made thanks to the development of a copper sulfide nanoparticle/carbon composite cathode and a hydride-based electrolyte. With the compulsive sales of electric vehicles and grid-scale energy storage systems on the rise, the need to explore alternatives to lithium-ion batteries has never been greater.…
