From Inorganic to Organic Iodine: Stabilization of I+ Enabling High-Energy Lithium–Iodine Battery

Organic materials have been considered a class of promising cathodes for metal-ion batteries because of their sustainability in preparation and source. However, organic batteries with high energy density and application potential require high discharge voltage, multielectron transfer, and long cycling performance. Here, we report an exceptional lithium-iodine (Li//I
