Ultrafast organic anodes designed for next-generation rechargeable batteries

Researchers from the Indian Association for the Cultivation of Science and the S. N. Bose National Centre for Basic Sciences, both under the Department of Science and Technology, have created a porous covalent organic framework (COF) anode that enables lithium‑ion batteries to reach 80 % charge in just over one minute while retaining performance over many cycles. The material also accommodates sodium ions, suggesting a route to affordable sodium‑ion batteries. The study underscores how rational molecular design can optimise ion transport, charge storage and structural stability, offering a low‑cost, fast‑charging, durable organic electrode for next‑generation rechargeable batteries.
