The object of research - physico - chemical properties of doped manganese (IV) oxide materials, electrochemical deposition of manganese (IV) oxide materials from fluorine - containing electrolytes. The purpose of the work - doping of manganese (IV) oxide materials can lead to changes in their phase ratios and surface states and improve the performance of lithium - oxygen battery in general: to increase the kinetics of processes involving oxygen, increase the reversal of charge / discharge cycles. Research methods - powder samples of manganese (IV) oxide were obtained from fluorine-containing electrolytes by anodic deposition on a platinum plate under galvanostatic conditions from an electrolyte of variable composition: 0.7M MnSO4; 0.1M HF; 1.5M (NH4) 2SO4; 0.1M CoSO4; 0.1M FeSO4 at a current density of 10A / dm2 and a temperature of 15-200C. The anode was a platinum plate with a larger area than the cathode 10 times. Electrocrystallized samples of electrolytes with the addition of cations were dried to constant weight at 110 ° C and studies on the kinetics of OER / ORR oxygen by CVA. Cyclic voltammograms were recorded on a potentiostat - galvanostat IPC - PRO with different potential sweep at different speeds in alkaline electrolytes 0.3M (0.5M) KOH / LiOH, saturated with oxygen.
