Lifecycle ageing tests on commercial 18650 Li ion cell @ 25°C and 45°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 deliverable https://everlasting-project.eu/wp-content/uploads/2020/03/EVERLASTING_D2.3_final_20200228.pdf

商用锂离子18650电池（正极采用富镍材料、负极采用硅/石墨（Si/Gr）基材料）的循环老化测试。每种测试条件均采用两颗电池开展测试。
测试电池在不同倍率（C-rate）与不同环境温度下进行老化。循环测试的荷电状态（SOC）窗口设置为10%至90%，该阈值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）。
循环测试会定期中断以执行参考性能测试。有关该老化测试的更多细节，可查阅EVERLASTING项目的交付文档：https://everlasting-project.eu/wp-content/uploads/2020/03/EVERLASTING_D2.3_final_20200228.pdf
