A notable family of such materials is organic battery electrode materials (OBEMs), which comprise electrochemically redox-active organic compounds including molecules, polymers, and organometallics where the organic components contribute to redox activity.
As mentioned above, the fabrication of battery electrodes usually involves mixing the organic electroactive materials with other components. Of major importance is the interfacing with conductive additives, given the insulating nature of most organic materials.
Organic compounds offer new possibilities for high energy/power density, cost-effective, environmentally friendly, and functional rechargeable lithium batteries. For a long time, they have not constituted an important class of electrode materials, partly because of the large success and rapid development of inorganic intercalation compounds.
Although organic compounds have already shown great potential for application in Al-ion batteries by virtue of their intrinsic merits, the research on organic positive electrodes for Al-ion batteries is still in a primary stage. There are numerous research topics for further enhancement of organic materials for Al-ion batteries.
Modern organic electrode materials will potentially enable the latest battery chemistries for meeting the cost, safety, and specific energy requirements of electric vehicles and grid storage.
In recent years, however, exciting progress has been made, bringing organic electrodes to the attention of the energy storage community. Herein thirty years' research efforts in the field of organic compounds for rechargeable lithium batteries are summarized.
