Organic cathode materials, derived entirely from earth-abundant elements, are in principle ideal alternatives but have not yet challenged inorganic cathodes due to poor conductivity, low practical storage capacity, or poor cyclability. Here, we describe a layered organic electrode material whose high electrical conductivity, high storage capacity, and complete insolubility enable reversible intercalation of Li⁺ ions, allowing it to compete at the electrode level, in all relevant metrics, with inorganic-based lithium-ion battery cathodes. Our optimized cathode stores 306 mAh g^-1_cathode, delivers an energy density of 765 Wh kg^-1_cathode, higher than most cobalt-based cathodes, and can charge-discharge in as little as 6 min. These results demonstrate the operational competitiveness of sustainable organic electrode materials in practical batteries.ACS central science569-578https://www.ebi.ac.uk/biostudies/studies/S-EPMC10979494biostudies-literatureA Layered Organic Cathode for High-Energy, Fast-Charging, and Long-Lasting Li-Ion Batteries.PMC10979494Dinca MOppenheim JJBanda HFranceschi AWang JChen TfalseA Layered Organic Cathode for High-Energy, Fast-Charging, and Long-Lasting Li-Ion Batteries.Eliminating the use of critical metals in cathode materials can accelerate global adoption of rechargeable lithium-ion batteries.
