Recent progress in the usage of metal organic polymers (coordination polymers (CPs), metal–organic frameworks (MOFs), Prussian blue and Prussian blue analogues (PBAs)) as electrodes in Li/Na rechargeable batteries has been reviewed.
Iodine-active graphene composites as cathode materials for rechargeable Li–I 2 batteries are fabricated. Soluble iodine redox species can be confined in the porous active graphene substrate, making the composites promising materials for high-rate energy storage devices.
