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. Energy density was ~0.35 Zhao et al.

Researchers call for integration of materials sustainability into battery research; the need for in situ monitoring

Green Car Congress

We need new storage technologies if more renewables are to be used on the electrical grid; similarly, the electrification of transport requires much cheaper and longer-lasting batteries. The size of these batteries (in comparison to those used for portable electronics) places severe pressure on materials resources. Elemental resources.
