Abstract
A lithium-ion battery electrolyte includes LiPFand an organic compound composition. The organic compound composition includes (1) vinylene carbonate (VC), (2) fluoroethylene carbonate (FEC), and (3) at least one ester (ES). A mole fraction of the LiPFin the electrolyte is approximately c(LiPF) mol. %. A mole fraction of the VC in the electrolyte is approximately c(VC) mol. %. A mole fraction of the FEC in the electrolyte is approximately c(FEC) mol. %. A mole fraction of the ES in the electrolyte is approximately c(ES) mol. %. In some embodiments, the mole fractions c(LiPF), c(VC), c(FEC), and c(ES) satisfy the following relations:8≤(LiPF)≤16;0.5≤(VC)≤5;10≤(FEC)≤26; and40≤(ES)≤75.
