An aluminum battery that can charge in a fraction of a second

Scientists in China and the United States investigated the inner workings of aluminum-ion batteries. With new insights into mechanisms at work within the battery during cycling, the group was able to demonstrate a battery capable of ultrafast charging, with the highest capacity so far reported for an aluminum battery.Aluminum-ion batteries promise significant improvements over today's lithium-ion technology. The ability to exchange three electrons per ion, compared to lithium's one, brings the potential for higher storage capacity. Al-ion batteries could also rely on more cheap/abundant materials, ...
