The range of kinetecs and thermodynamics parameters have been obtained using impedance spectroscopy method. Comparison of intercalation/deintercalation Li+ ion two models into lithium accumulator materials have been provided taken into account phase transitions and motion phase boundary. Mathematics simulation of phase boundary motion have been carried out. The models of e-FexSy / Li accumulators have been elaborated and investigated. Using fields: chemical power sources for electrotechnical,electronical, medicine and light industry.
