FIELD: chemistry.
SUBSTANCE: invention relates to chemical engineering and can be used in making solid-state lithium-ion batteries. Method of producing highly dispersed lithium-conducting solid electrolyte Li1.3Al0.3Ti1.7(PO4)3 for lithium-ion batteries includes grinding, fine mixing and activation of a reaction mixture containing titanium oxide, lithium carbonate, aluminium hydroxide, ammonium dihydrophosphate and carbon; thermal treatment; cooling and dispersion of synthesized solid electrolyte. Addition of carbon to the mechanically activated reaction mixture leads to suppression of foaming of this mixture during the degassing process, after which the carbon is oxidised.
EFFECT: obtaining highly dispersed lithium-conducting solid electrolyte Li1.3Al0.3Ti1.7(PO4)3 with improved conducting properties using mechanical activation and foam suppressing additive (carbon).
