Li studied the reaction mechanism of Grignard reagent in non-aqueous solution and theoretical work of electrolyte solution in his early years. He developed the theory of hydration enthalpy and the absolute hydration entropy of ions and deduced a formula used for the calculation of the physicochemical properties of ions in aqueous solution.His results are still cited by chemists working in this field.From the 1950s, he was engaged in the systematic research of mixed electrolytes. He determined the cell electromotive forces of Griganrd tragents in non-aqueous solution and proved the electrolytic properties of Grignard reagents in non-aqueous solution. He also proved that Harned rule could be used for the calculation of ion activity co-efficient of mixed electrolyte in solution and deduced an improved formula which can be used for the calculation of mixed electrolytes with defferent ions.
