Figure 9. (A) Cycling performance of NCM622||Li cells with DES-0 (without LiNO3 addition), DES-2 (with a 2 wt% LiNO3 addition), and commercial electrolytes at 25 °C and 0.5 C. The inserted images present the surface of separators with the electrolytes DES-0 (left) and DES-2 (right) after 100 cycles. (B) Rate performance of NCM622||Li cells with DES-2 and commercial electrolytes at 25 °C. (C) Cycling performance of NCM811||Li cells with different electrolytes at 25 °C and 0.5 C. (D) Voltage profile of NCM811||Li cells. This figure is reprinted (adapted) with permission from Liang et al.[171]. Copyright (2022) Wiley-VCH GmbH.
