Phase transformations occurring during the synthesis of oxide inorganic lithium-conducting materials, namely Li0.35La0.55TiO3 with a perovskite structure, Li1.3Al0.3Ti1.7(PO4)3 with a NASICON structure, and Li6.5La3Zr1.5Nb0.5O12 with a garnet structure, have been established. Film composite solid electrolytes based on a polyvinylidene fluoride polymer matrix filled with lithium salt LiClO4 and particles of inorganic lithium-conducting materials Li0.35La0.55TiO3 with a perovskite structure, Li1.3Al0.3Ti1.7(PO4)3 with a NASICON structure, and Li6.5La3Zr1.5Nb0.5O12 with a garnet structure have been developed. Modified cathode and anode materials were manufactured and their research was conducted in laboratory samples of solid-state lithium batteries.
