Due to the intensive production of electronic devices and apparatus, there is a growing demand for lithium-ion accumulators. The main requirements in these requests include more battery life, more safe and smaller in volume, and more convenient to use. In order to increase the capacity of batteries, scientists use the method of replacing graphite on the negative electrode of LIB with silicon, the theoretical capacity of which is 10 times higher. However, the main obstacles in using silicon as a negative electrode include an increase in the volume of the anode during lithization and processes occurring at the interface. Therefore, the development of silicon-based silicon oxide SiOx as a negative electrode will improve the electrochemical properties of silicon and study its nature and properties.
