Abstract

Electrolyte of lithium-ion battery usually goes through processes of filling, transportation and storage from the completion of manufacture to the use. Understanding the influence of long-term storage process on performance of lithium-ion battery electrolyte is of theoretical significance for production of lithium-ion battery. Scanning electron microscope (SEM) images showed that the solid electrolyte interface (SEI) film formed on the surface of the graphite electrode was thicker in the base electrolyte after 6 months of storage. The charge/discharge test results showed that the reversible cycle capacity and cycle stability (capacity retention rate) of graphite electrode decreased significantly after 6 months of storage. This might be due to the thicker SEI film formed on the surface of the graphite electrode, which in turn led to the instability of the lithium-ion intercalation process. When the base electrolyte containing 200 ppm resveratrol was stored for 6 months, the reversible capacity and cycle performance stability of the graphite electrode were even better than those in fresh base electrolyte. The results of electrochemical impedance spectroscopy (EIS) and cyclic voltammetry (CV) idicated that adding 200 ppm resveratrol to the base electrolyte could effectively suppress the decline in the electrochemical performance of the graphite electrode caused by long-term storage of the base electrolyte.
