Abstract: Lithium-ion batteries are widely accepted and used in portable electronics, cell phones, laptops, and electric cars. However, they are susceptible to fire, and water and they often malfunction under cryogenic conditions. Transition metal compounds are the most commonly used electrode materials for lithium-ion batteries. However, they are poor conductors, expensive, rare, and environmentally hazardous. Polymers containing conjugated carbonyl functional groups such as polyimide are effective alternative electrode materials for Li+ and Na+ batteries. Because of their environmental friendliness, as well as their high theoretical capacities, long cycle life, and fire-retardant properties, they are believed to be effective replacements for inorganic electrodes for rechargeable lithium batteries. However, polyimide is intrinsically electrical insulating, therefore its potential as electrode material has not been fully realized. Electrode materials made up of polyimide-graphene composites are capable of operation continuously without significant temperature increase because of graphene’s outstanding electrical conductivity and remarkable heat sink properties. Polyimide also has good reversible electrochemical activity due to the imide carbonyl groups and the conjugated double bonds in its backbone. The addition of Russian blue doped polypyrrole into the polyimide matrix improves the electrical and electronic properties of polyimide. The objective of this paper is to discuss the multifunctional properties of the new generation of hybrid organic electrode materials.
