Figure 3. (A) Cycling performance and Coulombic efficiency of NCM90||Li cells with different PFP contents in the voltage range of 3.0-4.3 V at 30 °C. (B, C) Charge/discharge curve evolution of cells (B) without and (C) with PFP. (D) Average charge/discharge voltage during cycling. (E) Chronoamperometry (floating charge at 4.3 V) results of NCM90||Li cells with STD and 0.2% PFP-containing electrolyte. STD: Standard electrolyte; PFP: pentafluoropyridine.
