Researchers at Hokkaido University, Tohoku University, and Nagoya Institute of Technology have developed a method to improve the energy capacity and cyclability of lithium-superrich iron oxide cathodes in lithium-ion batteries. By doping the cathode with small amounts of abundant elements like aluminum, silicon, phosphorus, and sulfur, they increased capacity retention from 50% to 90%. This innovation enhances the stability of batteries, reducing oxygen release during charge cycles. The approach offers a cost-effective solution for higher-capacity batteries used in applications such as electric vehicles and large-scale power storage systems. Future research aims to scale up the method for commercialization.
