Popis: | 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 31-203 m2/g were obtained. The specific capacity of TiO2 in lithium and sodium cells was determined. It is noted that the nature of the curves obtained, the specific capacity and its stability during cycling depend on the nature of the alkali metal cation and the surface properties of TiO2. |
