13-20 – High-Capacity Sodium-Ion Battery Electrode for Room Temperature Applications

Researchers at Kansas State University have developed a high-performance sodium-ion battery (SIB) electrode having high electrochemical capacity and improved cycling ability for Na+at room temperature. The electrode is binder-free and has been demonstrated to work both as a mechanically-flexible electrode and on convention copper foils. SIBs have drawn increasing attention because in contrast to lithium, sodium resources are practically inexhaustible, far lower priced, and involve a greener synthesis, while maintaining similar ion-insertion chemistry to lithium. Sodium has a very negative redox potential and a small electrochemical equivalent, making it the most advantageous element for battery applications after lithium. A major obstacle hindering the broad market penetration of existing sodium batteries is the long term stability and endurance of the battery components due to their operation at high temperatures (~300°C). Researchers at KSU have developed an SIB that runs at room temperature, which could bring about significant improvement in the safety and operational simplicity with respect to conventional high temperature SIBs.
