- Аннотация: Abstract—The goal of this work is to confirm our earlier conclusion that the regularities observed during theelectrodeposition of metallic lithium on copper and lithium electrodes can be associated with differences inthe properties of the so-called solid electrolyte interphase formed at these electrodes in contact with the electrolyte.To do this, we analyzed the electrochemical impedance spectra measured during the above processesby using the method of the distribution of relaxation times. The electrolyte addition with surfactants (the cetyltrimethylammoniumbromide and hexadecylpyridinium bromide) was shown to lead to a significant changein the properties of the solid electrolyte interphase layers and a noticeable increase in the values of the impedancecomponents associated with the Faradaic processes at these electrodes. This indicates an inhibition ofthe lithium electrodeposition processes and the related process of dendrite formation under these conditions.At the same time, no such impedance components were observed at the fresh-formed deposit, which confirmsour earlier conclusion that the effects of surfactants on the dendrite formation are associated with thechanges in the properties of the solid electrolyte interphase layers in the presence of the surfactants, ratherthan the surfactants’ adsorption at lithium and blocking of the dendrite growth.
