Low pressure carbon dioxide solubility in lithium-ion batteries based electrolytes as a function of temperature. Measurement and prediction

► CO2 solubility is measured in pure alkylcarbonates and their binary mixtures. ► The CO2 solubility varies significantly for concentration LiPF6, LiTFSI and LiFAP salt. ► The dissolution of the CO2 in all solvents is entropy-driven and exothermic. ► CO2 solubilities were predicted using COSMOThermX and compared to measurements.
