A recent study affiliated with UNIST has introduced a novel electric vehicle (EV) battery technology that is more energy efficient than gasoline-powered engines. The new technology involves replacing battery packs instead of charging them, bypassing the slow-charging issues of existing EV battery technology. It also provides lightweight, high-energy density power sources with little risk of burning or explosion. This breakthrough has been led by Professor Jaephil Cho and his research team in the School of Energy and Chemical Engineering at UNIST. Their findings have been published in Nature Communications.
