Bannik N. Electrochemical system: Sulfide electrode - aprotic electrolyte for lithium accumulator

Electrochemical processes in the system FeS2- electrode, aprotic electrolyte for lithium accumulator. Establishment of the influence of aprotic electrolyte composition , the circuit of electrochemical processes proceeding on a positive electrode at cycling, development of the production method of positive electrode and tests of the models of power sources. Galvanostatic cycling, cycling voltammetry, method of electrode impedance, IR- spectroscopy, method of X-ray phase analysis, atomic - force microscopy. For the first time, the principle possibility of FeS2 electrode cycling in the electrolyte based on aprotic solvents within the temperature range of +10- +40 C and lithium accumulator production is shown. The circuit of the electrochemical processes proceeding on positive FeS2 electrode at its cycling is shown. The proposed electrolyte composition can be used at industrial production of the power sources based on Li - FeS2.
