Next-generation batteries will probably see the replacement of lithium ions by more abundant and environmentally benign alkali metal or multivalent ions. A major challenge, however, is the development of stable electrodes that combine high energy densities with fast charge and discharge rates. Scientists now report a high-performance cathode made of an organic polymer to be used in low-cost, environmentally benign, and durable sodium-ion batteries.
