AP19576865 Extraction and research of MXene modified materials for electricity storage

Relevance

The relevance of the project is due to the global growth in demand for highly efficient and durable electric energy storage devices for use in portable electronics, electric vehicles and energy storage systems. Traditional materials such as graphite are limited in capacity and stability. The use of modified MXene materials with the introduction of nanosilicon opens the way to the creation of a new generation of electrodes with improved characteristics – increased specific capacity and service life. The project meets the urgent tasks of developing "green" energy and the high-tech industry, as well as contributes to scientific and technological progress in the field of materials science.

Purpose

The aim of the project is to develop a method for producing MXene materials and their modification by embedding silicon into the resulting structure, the end result of which is a material with 2 times more charge/discharge cycle stability and specific capacity compared to graphite, used as an active electrode material in electric energy storage devices.

Expected and achieved results

The most optimal parameters for the synthesis of modified MXene materials using NaOH and HCl were studied and determined, each of which affects the surface groups of MXene materials and the further process of silicon incorporation. A solution of dodecylamine (DA) dissolved in tetraethoxysilane (TEOS) in a different molar ratio of MXene/DDA/TEOS in an argon atmosphere was used. The optimal parameters for the modification of MXene materials are determined by synthesizing them at various parameters at the stages of mixing, filtration, drying, and calcination in an argon atmosphere (temperature and heating rate).
