In this work, we report a systematic investigation about the chemical-physical properties of mixtures containing glyoxylic solvents (tetramethoxyglyoxal (TMG) and tetraethoxyglyoxal (TEG)) and organic carbonates, and about the use of these blends as electrolytes for lithium-ion batteries (LIBs). We showed that these mixtures display promising conductivities and viscosities as well as high thermal stability. Furthermore, they also display significantly higher flash points (up to 60 °C) than the state-of-the-art LIB electrolytes. These mixtures can be successfully utilized for the realization of lab scale LIBs displaying high stability and good rate capability at high C-rate. Furthermore, LIBs containing this innovative electrolyte display good stability at room temperature as well as at 40 °C and 60 °C. Considering these results, mixtures of glyoxylic acetals and organic carbonates appear as promising electrolytes for advanced LIBs. [ABSTRACT FROM AUTHOR]
