      abstract     = {A poly(vinylidene difluoride-co-hexafluoropropylene)
                      (PVdF-HFP)-based gel polymer electrolyte (GPE) containing
                      propylene carbonate (PC)-based liquid electrolyte was
                      developed to enhance the safety performance of
                      LiNi0.5Mn0.3Co0.2O2/graphite (NMC532/graphite) lithium ion
                      batteries. The PC-based liquid electrolyte (PEV-LE) consists
                      of 1 mol L−1 LiPF6 as lithium salt, PC as the main
                      solvent and ethylene sulfite (ES, $2\%$ by weight) as well
                      as vinylene carbonate (VC, $2\%$ by weight) as solid
                      electrolyte interphase (SEI) forming additives.
                      Electrochemical impedance spectroscopy (EIS) and X-ray
                      photoelectron spectroscopy (XPS) revealed that the
                      combination of ES and VC additives facilitates the formation
                      of effective interphases at the respective
                      electrolyte/electrode interfaces, thus contributing to a
                      remarkable cycle life of NMC532/graphite cell comprising
                      PEV-GPE. Flash point measurements and differential scanning
                      calorimetry (DSC) confirmed significantly improved safety
                      performance of PEV compared to the state-of-the-art
                      electrolyte. PEV-GPE is a promising alternative to
                      state-of-the-art electrolyte as it shows extended cycle life
                      and enhanced thermal stability in NMC532/graphite lithium
                      ion cells.},
