The duties are distributed throughout the whole study period, scored by credits/points and checked in defined dates. The current point evaluation of all activities of the student is summarized in the “Total point rating of doctoral student” document and is part of the ISP. At the beginning of the next study year the supervisor highlights eventual changes in ISP. By October, 15 of each study year the student submits the printed and signed ISP to Science Department of the faculty to check and archive.
Within the first four semesters the student passes the exams of compulsory, optional-specialized and/or optional-general courses to fulfill the score limit in Study area, and concurrently the student significantly deals with the study and analysis of the knowledge specific for the field defined by the dissertation thesis theme and also continuously deals with publishing these observations and own results.

  34. Sodium-ion Batteries

    The basis of this work will be research and development in the field of sodium-ion batteries. The sodium-ion batteries belong to the group of so-called post-lithium systems, the successors of the existing lithium-ion technology. A sodium-based battery is an environmentally friendly, cost-effective (virtually unlimited source of sodium element) alternative to lithium-ion batteries. There is no need for a new technology process for the production of these batteries, since they are based on the same technology manufacturing process as the lithium-ion batteries. A major issue of sodium-ion battery is the development of electrode materials (electrodes), which is the key that opens the mass production of these accumulators. The field of application of soda-ion batteries is primarily renewable energy sources. The need for batteries which will store the energy produced from renewable energy sources lies in the essence of renewable sources themselves. The sun and wind are non-dispatchable, it is not possible to influence when they produce electricity. In order to effective utilize the energy produced from these sources, it is essential to store this energy. This requires batteries that store energy and allow it to be used on demand (efficiently). If we are talking about the sustainable development of human society, we must learn how to effectively use energy from renewable sources and this is not possible without the accumulation of the electric energy.

The aim of this project is to develop a methodology that will make it possible to use this microscope technique to observe the processes that are taking place in different types of battery systems in different operating modes. The outcome of the project will to verify the existing knowledge of the processes taking place in the batteries and to obtain new knowledge about these processes.

  4. Methods for precise 3D distance measurement

    Size measurement of the object is becoming important together with progress of 3D printing technology, augmented reality, navigation systems and various portables devices. There exist several approaches for distance measurement suitable for particular applications with different resolution, measurement range and speed of measurement. The work will be focused on principles and possibilities of particular method utilization, research and experimental verification.

  5. New gel polymer electrolytes for Li-ion and post-lithium accumulators

    This work deals with new gel polymer electrolytes, which should replace the liquid and polymer electrolytes used in Li-ion and post-lithium-ion accumulators. Gel electrolytes based on copolymers of methyl methacrylate with ethyl methacrylate, butyl methacrylate and lauryl methacrylate will be prepared.

  6. Perovskite solar cells

    The work is aimed at studying the properties of perovskite solar cells and monitoring the impact of changes in various functional structures in the cell on the behavior of the entire system. The student will use advanced static and dynamic photoelectric methods in the studies.

    Tutor: Novák Vítězslav, doc. Ing., Ph.D.

  7. Research of supersonic flow on the boundary of continuum mechanics.

    The basis of the dissertation thesis is the research in the field of supersonic flow at low pressures in the area of continuum mechanics with respect to the functionality of the Environmental Scanning Electron Microscope when pumping vacuum chambers.

    Tutor: Maxa Jiří, doc. Ing., Ph.D.

  8. Study of battery characteristics depending on operating conditions

    For selected accumulators of pouch construction will be studied the influence of operating conditions on electrochemical properties such as capacity, capacity at high load, internal resistance and cyclability. The influence of positive and negative temperatures on these parameters will be studied by electrochemical methods such as galvanostatic cycling or electrochemical impedance spectroscopy. Simultaneously, temperature and dimensional changes of the cell during these analyzes will be monitored. The influence of different pressure applied on the battery walls on electrochemical properties during its cycling will be studied. At the end the battery will be disassembled and post-mortem analysis will be performed. The work will be coordinated in cooperation with Škoda Auto

    Tutor: Kazda Tomáš, doc. Ing., Ph.D.

  9. Technology for recycling of lithium-ion accumulators

    The topic is focused on the issue of lithium-ion accumulators and their recycling. The aim will be to propose new methods and modify the methods currently used for the recycling of the lead-acid accumulators for the recycling of the lithium-ion accumulators in order to achieve the highest efficiency of recycling of the electrode materials. For the recycling process will be investigated new types of environmentally friendly procedures and solvents that can replaced currently used very aggressive and non-organic solvents. Total profit of recycled materials should exceed 70% of the original mass of the accumulator. The results obtained in this research will help to increase the long-term sustainability of the technology of lithium-ion accumulators needed to develop electromobility.
