The aim of the work was to study the possibility of suppressing the formation of dendrites of metallic lithium during the operation of secondary lithium batteries, including those with a metallic lithium anode. The electrochemical deposition of lithium on copper and lithium substrates in the presence and absence of two surfactants, cetyltrimethylammonium bromide and hexadecylpyridinium bromide was studied by current transient and electrochemical impedance methods. A typical lithium-ion battery electrolyte based on lithium hexafluorophosphate and a mixture of ethylene carbonate (EC) and diethyl carbonate (DEC) was used. It was shown that the presence of the so-called SEI (solid electrolyte interphase) layer on the electrode surface has a significant effect on the electrodeposition process. It was also shown that the mechanism of lithium electrodeposition on copper and lithium substrates is different. It can be assumed that the observed effect of surfactants on the dendrite formation is associated not with the adsorption of surfactants on lithium and blocking the growth of deposits, but with the effect of surfactants on the properties of the SEI layer formed on these substrates.
