The study of the prospects for the use of Li0.15Sr0.85TiO3 ceramics

The paper presents the results of a study of structural characteristics, as well as the possibility of using Li0.15Sr0.85TiO3 ceramics as anode materials for lithium-ion batteries. It has been established that the structure of ceramics is an accumulation of dendritic agglomerates consisting of spherical and spherical nanoparticles with a developed specific surface. According to X-ray phase analysis, the ceramic crystal structure is a mixture of two phases: cubic SrTiO3 and orthorhombic Li2Ti3O7, with a predominance of the SrTiO3 phase. During the life tests, it was found that in the case of the 1000 mAh/g mode, the resource number of cycles is close to 480-500 cycles, which is typical for most silicon-based structures that are standardly used as the basis for lithium-ion batteries. An increase in the charging capacity to 1500 mA h/g leads to a slight decrease in the resource lifetime-420 cycles to a decrease in capacity below 80%. Based on the conducted tests of life tests, the prospects of using ceramics based on Li0.15Sr0.85TiO3 as the basis for lithium-ion batteries have been established.
