Baydich L. Hexafluorophosphates of the alkaline-earth metals: synthesis, characteristics, usage in the supercapacitors.

Processes in the system: MePF6-PC (Ме=Li, Na, K). Physicochemical properties of the electrolyte on the basis hexafluorophosphate in the aprotic solvent were studied. the method of receiving electrolyte for supercapacitors was elaborated. The new method of receiving solution of electrolyte (NaPF6-PC) for supercapacitors was elaborated. Research methods: the chemical and component analyses were used as well as the definition of the electro-chemical properties of the products, NMR-spectroscopy 19F, 31Р quantum - chemical calculations of the ion pairs with the "Gaussian-2003" programme. For the first time such results as experimental data of the research of the system NaPO3-H2O phase equilibrium, theoretical calculations of the interpartiche interaction of system MePF6-PC (Me=Li, Na, K) have been gotten. A new method of getting electrolyte for supercapacitors (NaPF6-PC) wes proposed. Applications: the chemistry of fluorine complex solutions and getting the electrolyte solutions for supercapacitons.
