RIKEN team develops high-performance lithium-iodine battery system with higher energy density than conventional Li-ion

Green Car Congress

The working concept of I3 – /I – redox reaction in the aqueous Li-I 2 battery. A team from Japan’s RIKEN, led by Hye Ryung Byon, has developed a lithium-iodine (Li-I 2 ) battery system with a significantly higher energy density than conventional lithium-ion batteries. Schematic illustration of the aqueous Li-I 2 battery.
