Energy storage devices based on multivalent metals have the potential to meet the needs of large-scale energy storage, due to the relatively high abundance and low-cost of elements such as magnesium, calcium, aluminum and zinc. However, studies of previous multivalent metal-ion chemistries demonstrated that significant technical challenges need to be overcome to move these nascent technologies toward commercialization, such as developing new electrolyte formulations and cathode materials as well as enabling high capacity metal anodes. JCESR’s multivalent-ion battery technology portfolio has been developed to addresses these challenges and now features more than seven granted US patents including new electrolytes, additives and cathode materials for magnesium-ion and calcium-ion battery applications.
