      abstract     = {Effective electrolyte compositions are of primary
                      importance in raising the performance of lithium-ion
                      batteries (LIBs). Recently, fluorinated cyclic phosphazenes
                      in combination with fluoroethylene carbonate (FEC) have been
                      introduced as promising electrolyte additives, which can
                      decompose to form an effective dense, uniform, and thin
                      protective layer on the surface of electrodes. Although the
                      basic electrochemical aspects of cyclic fluorinated
                      phosphazenes combined with FEC were introduced, it is still
                      unclear how these two compounds interact constructively
                      during operation. This study investigates the complementary
                      effect of FEC and ethoxy(pentafluoro)cyclotriphosphazene
                      (EtPFPN) in aprotic organic electrolyte in
                      LiNi0.5Co0.2Mn0.3O ∥ SiOx/C full cells. The formation
                      mechanism of lithium ethyl methyl carbonate (LEMC)-EtPFPN
                      interphasial intermediate products and the reaction
                      mechanism of lithium alkoxide with EtPFPN are proposed and
                      supported by Density Functional Theory calculations. A novel
                      property of FEC is also discussed here, called
                      molecular-cling-effect (MCE). To the best knowledge, the MCE
                      has not been reported in the literature, although FEC
                      belongs to one of the most investigated electrolyte
                      additives. The beneficial MCE of FEC toward the
                      sub-sufficient solid-electrolyte interphase forming additive
                      compound EtPFPN is investigated via gas chromatography-mass
                      spectrometry, gas chromatography high resolution-accurate
                      mass spectrometry, in situ shell-isolated
                      nanoparticle-enhanced Raman spectroscopy, and scanning
