High-energy, fast-charging, long-life lithium-ion batteries using TiNb2O7 anodes for automotive applications
چکیده انگلیسی
Electrochemical properties of TiNb2O7 (TNO) electrodes during lithium storage have been studied in order to develop an alternative anode with high-capacity, fast-charging, and long-life to Li4Ti5O12 (LTO) in lithium-ion batteries. High-density TNO (HD-TNO) composite electrode consisting of micro-size spherical TNO secondary particles coated with carbon exhibited high-rate capability, long cycle-life, and a high volumetric capacity of more than twice that of LTO composite anodes. Large-size lithium-ion batteries using the HD-TNO anode and a LiNi0.6Co0.2Mn0.2O2 (NCM) cathode with a capacity of 49 A h were fabricated for automotive applications, and were found to have a high energy density of 350 W h L−1, a high input-power density of 10 kW L−1 for 10 s at 50% state of charge (SOC), and fast-charging from 0% to 90% SOC in less than 6 min. The capacity retention at 7000 cycles was 86% by full charge-discharge cycling at 1C rate. Cycle life was predicted to be 14000 cycles at 80% capacity retention. It was demonstrated that the TNO/NCM batteries have high energy-density, fast-charging, and long cycle-life for automotive applications such as electric vehicles with long driving ranges by fast-charging.
