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型电池（富镍正极、硅/石墨（Si/Gr）基负极）的循环老化测试。每组测试条件均采用两颗电池开展重复测试。
测试电池在不同倍率（C-rate）与不同环境温度下进行老化。电池的循环工作区间设置为10%至90%荷电状态（State of Charge, SOC），该区间基于全新电池定义且保持固定（即不会随电池老化过程更新）。
循环测试过程会定期中断以执行参考性能测试。有关老化测试的更多细节，可参阅该项目交付文档：https://everlasting-project.eu/wp-content/uploads/2020/03/EVERLASTING_D2.3_final_20200228.pdf
