Nikolay Ovsyannikov
PhD thesis: Redox flow batteries enhanced by solid boosters
Supervisor: Prof. Keith J. Stevenson
IDC Committee members: Prof. Keith J. Stevenson, Assistant Prof. Stanislav Fedotov and Assistant Prof. Victoria Nikitina
Nikolay graduated with honors from Lomonosov Moscow State University (Department of Fundamental Physical and Chemical Engineering; Bachelor in Applied Mathematics and Physics) in 2019 and from Skoltech (Materials Science program; Master in Materials Science) in 2021. During his bachelors, he was doing his research in the RAS Institute of Problems of Chemical Physics (Chernogolovka, Russia) focusing on functional inorganic coatings deposition by vacuum aerosol deposition method. One of the key applications was the manufacturing of all-solid state thin-film battery: in 2019, due to high interest in electrochemical energy storage devices, he joint Skoltech.
Doing his Master Thesis research on composite polymer-ceramic Li-conductive membranes for redox flow batteries, Nikolay decided to devote his research to the search and development of novel materials for flow batteries. During PhD, he is focusing on introduction of solid boosters in redox flow batteries, which is one of the promising strategies to enhance their energy density. Nikolay’s research includes both study of fundamental electrochemical interaction between solid booster and dissolved mediator and prototyping of flow battery with solid booster.
