Аннотация

Composite solid electrolytes LiClO4 - CND, where CND is the nanodiamonds powder, were prepared and their properties studied in the concentration range from 0 to 0.95 M fraction of CND at temperatures from 25 to 200 °C. Composites were characterized by X-ray powder diffraction, thermal analysis (TG/DSC). According to the XRD data, in the temperature range of 30-200 °C, only phases of anhydrous, hydrated lithium perchlorate and nanodiamonds are present in the composites. According to TG data, the amount of possible lithium chloride resulting from the decomposition reaction on the surface of nanodiamonds was estimated, which corresponds to 83% of the coverage with a monolayer of LiCl. The first experiments on electrical conductivity showed an increase in electrical conductivity by 3 orders of magnitude for a composition with * = 0.7 compared to pure LiClO4 (r = 1∙10-4 S/cm at T = 150 °C).
