    Abstract: Organic electrode materials are widely applied for metal (lithium and sodium)-ion batteries (LIBs and SIBs) due to their structural diversity and redox reversibility. Molecule-aggregation organic electrodes in principle possess the “single-molecule-energy-storage” capability for metal-ion rechargeable batteries. Nevertheless, the small-molecule org... Show More

    Abstract: The state of charge (SOC) of lithium-ion battery is a variable and cannot be measured directly by sensors. Therefore, accurate estimation of battery state of charge is the key to ensure the safe and reliable operation of battery management system (BMS) and reduce the required battery cost. In the research of estimating the state of charge of lithiu... Show More
