A functional electrolyte containing propyl 4-methylbenzenesulfonate (PMBS) additive is developed to improve the performance of the LiNi0.8Co0.1Mn0.1O2 (NCM811)/graphite pouch full cells, especially the cycling lifetime under low temperature. It is indicated that the addition of PMBS into the electrolyte facilitates the formation of stable and low impedance interfacial films of the NCM811 cathode and graphite anode due to the preferential decomposition of PMBS over solvent molecules. Compared to the cells without additives, the cells containing 2% PMBS exhibit enhanced performance, and the capacity retention rate increases from 55.97% to 87.20% after 1200 cycles at 25 °C. And under the temperature condition of −10 °C, the capacity retention rate increases from 55.37% to 98.02% after 100 cycles, indicating the unique effect of PMBS on the low-temperature cycling performance of high-nickel lithium-ion batteries.
