Ph.D. thesis: “High-capacity alloying anode materials for sodium-ion batteries”
Supervisor: Assistant Prof. Stanislav Fedotov
Nikita was graduated Chemistry Department of Lomonosov Moscow State University in 2020. His scientific interests are focused on the developing of technology of the hydrothermal synthesis of electrode materials for metal-ion batteries. Master thesis was devoted to potassium-ion rechargeable batteries. For this, a new titanium-containing cathode material with extraordinarily high redox potential was synthesized and characterized. This work first time demonstrated that titanium can be used to design prospective environmentally benign materials. Along with this work was also developed a process of fine carbon-coating of polyanion electrode materials using a special organic polymer for improving their rate capability and stability at high current densities. This technology was resulted into patent application at Skoltech.
