Synthesis of Perspective materials for cathodes of Li-ion batteries with low cobalt content
Hálová, Hana ; Kazda, Tomáš (referee) ; Chladil, Ladislav (advisor)
The thesis is focused on cathode materials with low cobalt content. In the work, there is a comparison of cathodes with cobalt, low cobalt content, and without it. The materials are compared in terms of theoretical specific capacity, commonly achieved specific capacity within first cycles, energy density, and cycle life. Taking into account these criteria there have been selected perspective high voltage cathode materials. For selected cathode materials, various synthesis options were compared, with spray-drying synthesis chosen for the research conducted within the experimental part of the thesis. The thesis also describes the preparation of a laboratory apparatus for spray-drying synthesis, including a particle capture system. Furthermore, systematic experiments were carried out to optimize the high-temperature calcination process.
