Two key challenges in chemistry innovation are solved simultaneously by exploring chemical opportunities with artificial intelligence.

With the use 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. Tohoku University researchers have recently developed a prototype calcium metal rechargeable battery capable of 500 cycles of repeated charge-discharge - the benchmark for practical use. The breakthrough was made thanks to the development of a copper sulfide nanoparticle/carbon composite cathode and a hydride-based electrolyte.
