Triethyl 2-(1,3-oxazolidin-3-yl)ethyl orthosilicate (OZOS) has been studied as an additive to the 1 M LiPF6/EC:EMC:DMC:PC (3:6: 1:1) electrolyte of lithium-ion battery with graphite anode by cyclic voltammetry and chronopotentiometry. The above additive in amounts of 0.25, 0.5, and 1.0 wt.% increases the first cycle efficiency (ratio of charge to discharge capacity) by 0.4-1.0% as compared to the base electrolyte.
