Structure and scope of master theses. It consists of seven 8 parts: literature
review, research materials and methods, results, occupational health and safety in
emergencies, economic section, development startup project, conclusions and
reference list. Master thesis include: 101 pages, 67 pictures, 20 tables, 86 references.
Actuality. Modern electronics require the use of portable energy sources with
high indicators of electrochemical characteristics. Currently, the most promising means
of energy conservation are lithium power sources (LPS).
The purpose and tasks of the research. The aim of the work was to determine
the effect of the duration of mechanical processing on the morphology of the powder
SiO2/TiO2 nanocomposite and electrochemical characteristics of LPS with cathodes
based on such nanocomposites.
The object of the study – SiO2/TiO2 nanocomposite with a component ratio of
80/20 % after different duration of treatment.
Subject of research – SEM images with magnification 500 and 2500 times, data
of USXES and galvanostatic investigation.
Methods of research – SEM, USXES, galvanostatic analysis.
Scientific innovation. The determination of the effect of mechanical activation
on the morphological features of SiO2/TiO2 nanocomposite and dependence of
galvanostatic characteristics of LPS from these features.
Practical significance of the obtained results. The generalized results can be
used to predict changes in the structural and electrochemical characteristics of LPS
with cathodes based on other nanosized oxides.
Approbation of coursework materials. The result of work presented in the
international conferences HighMatTech-23 and XIX – ICPTTFN.
