In diploma I will present high-entropy materials, where I will focus on the use of these materials for energy storage. High-entropy materials include high-entropy alloys, high-entropy ceramics, which include high-entropy oxides. These materials show great potential in applications for electrical and photocatalysis, hydrogen and energy storage, magnetic and dielectric components. High-entropy materials is stable crystalline material consisting at least five different metal elements, where each separate system can have its own crystal structure. They are suitable for use in batteries because they have high electronic and ionic conductivity, high capacity, good magnetic and dielectric properties ... High-entropy oxides can be used as an electrode material in lithium-sulfur batteries. Electrodes in such batteries contain elements such as Mg, Co, Cu, Ni, Zn, O, Fe ... which increases their stability and impoves the capacitance and number of cycles.
In preparing my diploma, I will focus on materials useful in storing electricity – batteries. Diploma will be focused mainly on the presentation and review of current materials in the field. I will study the influence of different synthetic pathways and preparations on the final properties of materials and target characteristics of batteries.
