Credit: Yale University ________________________________________________________________________________________ Researchers at Yale and Donghua University in China have developed a new process for creating lithium metal that may boost the energy and capacity of rechargeable batteries. Lithium metal is considered the best option as a material for anodes in high-energy batteries, the researchers said, because of the metal's high potential for providing large amounts of energy and capacity in a given mass. Yet existing lithium metal electrodes, limited by low capacity and utilization efficiency,...
