Ефективність циклування нанорозмірного TiO2 в літієвих та натрієвих джерелах струму

Abstract

The paper presents the results of studies of nanosized titanium dioxide (TiO2) samples synthesized by alkaline hydrolysis. The surface properties of the samples were modified using high-temperature annealing. As a result, samples with a specific surface area of 80-174 m2/g were obtained. The values of specific capacity in lithium and sodium cells were determined by galvanostatic cycling method. It is noted that the nature of the curves obtained, the values оf specific capacity and its stability during cycling depend on the nature of the alkali metal cation and the surface properties of TiO2.
