Mie University team working on aqueous li-air batteries; 300 Wh/kg

Green Car Congress

Researchers at Mie University in Japan have developed a new protected lithium electrode for aqueous lithium/air rechargeable batteries. Lead researcher Nobuyuki Imanishi said that the system has a practical energy density of more than 300 Wh/kg, about twice that of many commercial lithium-ion batteries.
