Researchers from the Indian Association for the Cultivation of Science (IACS) and S. N. Bose National Centre for Basic Sciences (SNBNCBS), both institutes of the Department of Science and Technology, have developed a breakthrough porous organic anode material for next-generation rechargeable batteries. The new covalent organic framework (COF) material enables lithium ions to move much more easily, addressing the growing demand for energy storage for electric vehicles, smartphones, laptops, and renewable energy applications.
The material demonstrated exceptional performance in practical battery testing, enabling batteries to reach 80% charge in just over one minute while maintaining excellent performance over many charging and discharging cycles. Additionally, the researchers found that the same material can effectively store sodium ions, opening the door to the development of more affordable sodium-ion batteries in the future. This successful operation in a practical battery device demonstrates the material's potential for real-world applications.
The breakthrough highlights how rational molecular design of covalent organic frameworks can simultaneously optimize ion transport, charge storage, and structural stability, providing an effective strategy for developing low-cost, fast-charging, and durable organic battery electrodes. The research represents a collaborative effort between IACS and SNBNCBS in addressing critical challenges in sustainable energy-storage technologies, with the findings published in a scientific journal (DOI: 10.1002/adma.73960).
