By late January 2021 and after more than a year of intense effort spent in development, pilot studies, trial production, designing, and industrialization process, we report that 2U’s battery team has achieved significant progress. That means 2U lithium batteries, by energy density, could soon power Electric Vehicles(EV) to travel more than 2,000 km on a single charge!According to the 2020 testing result, Li-S battery achieves 1700 cycles at a 2C charging and discharging rate while maintaining a coulombic efficiency of no less than 99.3%. The achieved decay rate was 0.01% per cycle. At the end of the cycling test, the cathode’s remaining energy density could still reach 1484Wh/kg. The Cathode core material submitted Australia patent application on 30 January 2020 (Application number 2020900246). The International IP application was submitted on 29 November 2020 (Application number PCT/AU2020/051294). The Cathode core material can be mass-produced.
