Fig. 10: Electrochemical performances of LIBs using LiNi0.5Mn1.5O4 as positive electrode material and graphite as negative electrode material with DMDOHD-based electrolyte.
From: A dicarbonate solvent electrolyte for high performance 5 V-Class Lithium-based batteries
a The first galvanostatic charge-discharge curves of the graphite | |LiNi0.5Mn1.5O4 cells cycled in different electrolytes at a rate of C/10 (1 C corresponds to 142 mA g−1 based on the mass of LiNi0.5Mn1.5O4). LLF represents 1 M LiPF6 + 0.5 M LiDFOB + 6wt.% FEC. Comparison of the (b) Coulombic efficiency and (c) cycle life of the graphite | |LiNi0.5Mn1.5O4 cells in different electrolytes (C/5 cycling rate). d Cycling stability of the graphite | |LiNi0.5Mn1.5O4 pouch cells in different electrolytes (0.5 C charging-1 C discharging) at 25 °C. FEMC and PS represent 2,2,2-trifluoroethyl methyl carbonate and 1,3-propanesultone, respectively. 1 M-LPF-PS-FDFxyz (x + y + z = 10) represents 1 M LiPF6 + 4 wt.% PS in FEC/DMDOHD/FEMC (x/y/z, vol.).
