Lifecycle ageing tests on commercial 18650 Li ion cell @ 10°C and 0°C

Cycling ageing of Li ion 18650 commercial cell (Ni rich positive electrode and Si/Gr based negative electrode).Each test condition was applied on two cells.<br>The cells were aged at different C-rates and different environmental temperatures.The cells were cycled within a 10-90%SOC window. These levels are defined from fresh cells and fixed (i.e. not updated with ageing).The cycling is regularly interrupted to run a reference test.More details of the ageing tests can be found in the Everlasting deliverablehttps://everlasting-project.eu/wp-content/uploads/2020/03/EVERLASTING_D2.3_final_20200228.pdf商用锂离子18650电池（富镍正极与硅/石墨（Si/Gr）基负极）的循环老化测试。每种测试条件均采用两节电池开展试验。 测试电池在不同倍率（C-rate）与不同环境温度下进行老化循环。 电池的循环区间设置为10%至90%荷电状态（SOC）窗口，该区间基于全新电池定义且保持固定（即不会随电池老化进行更新）。 循环测试过程会定期中断，以执行参考性能测试。 本次老化测试的更多细节可参阅Everlasting项目交付文档：https://everlasting-project.eu/wp-content/uploads/2020/03/EVERLASTING_D2.3_final_20200228.pdf
