In 2016 a French research team reported that by replacing cobalt with manganese more than doubles the battery capacity but performance degraded significantly. A team of researchers in the US (Northwestern University, MIT) found that the reason behind the material’s high capacity was because oxygen participates in the reaction process. They predicted that mixing chromium or vanadium with lithium-manganese-oxide will produce stable compounds that maintain the cathode’s unprecedented high capacity. They will experimentally test these theoretical compounds in the laboratory…read more. Open Access TECHNICAL ARTICLE
