Battery Degradation Dataset - Li Plating And SEI Growth
Description
45 commercial Li−ion coin cells (LIR2025H produced by EEMB Battery) with nickel manganese cobalt oxide (NMC) cathodes and graphite anodes are cycled on a Landt CT3001A battery test system to generate cycle data. The cells are charged under CCCV profile with constant current range from 0.2C to 5.5C. The cutoff voltage ranges from 4.2V to 4.4V. All cells are discharged with C/5. The detail charging profile can be found in the charging policy.xlsx.
