FORMATION OF ACTIVE INTERPHASE ON THE IRON PARTICLES IN C/PVDF ELECTROCHEMICAL SYSTEMS
The possibility of formation of an active interphase on iron particles in C/PVDF has been dictated by the thermochemical reactions of iron and iron oxides in the presence of carbon. The composition with polyvinylidene fluoride (PVDF) changed the redox activity of iron particles and decreased pure ir...

| description | The possibility of formation of an active interphase on iron particles in C/PVDF has been dictated by the thermochemical reactions of iron and iron oxides in the presence of carbon. The composition with polyvinylidene fluoride (PVDF) changed the redox activity of iron particles and decreased pure iron (Fe0) amount by 0,24 wt. %. The surface properties of various compositions have been characterized by scanning electron microscopy with the analytical mode for determining the relationship between the microstructure and local thermal reactions on the iron particle surface. A relationship between the surface composition, morphology and electrochemical behavior of the Fe/C/PVDF electrodes has been found. Electric current affects the surface morphology and changes it from a mosaic structure to a monolith in atmosphere oxygen. The electrochemical properties of Fe/C/PVDF electrodes have been tested using cyclic voltammetry (CVA). The long air contact (for more than 3 hours) during electrochemical cycling changes the surface structure in the direction of decreasing crystallinity. The Fe/C/PVDF electrode can be charge in neutral solutions (pH ~7). |
