The shift toward electric vehicles (EV shift) is being accelerated worldwide to reduce C02 emissions during running. In addition, more renewable energy is being introduced, increasing the demand for secondary batteries. Against this backdrop, studies are being conducted to increase the energy density of lithium-ion batteries for EVs and stationary battery storage. The company is also focusing on developing new batteries, e.g., all-solid-state batteries that can further improve energy density and sodium-ion batteries that use sodium instead of lithium, a rare metal. Kobelco Research Institute supports the development of batteries through its evaluation/analytics technologies, including "the prototype production of lithium-ion batteries, all-solid-state batteries, and sodium-ion batteries," "battery characteristics evaluation technology, " "reaction distribution analysis technology in battery cells," "redox reaction analysis technology, " and "non-destructive deterioration diagnosis technology for reuse," thus contributing to the realization of carbon neutrality.
