Materials for energy conversion and storage
This course is part of the programme:
Objectives and competences
The students are introduced into basic principles of functioning of devices for electrochemical conversion and storage. They are acquainted with physical-chemical mechanisms that are exploited by such devices during their operation. They learn about the relationship between the structure, morphology, composition and functionality of materials constituting such devices. They are acquanted with additional effects occurring upon integration of active materials into electrode composites. They are introduced into techniques for investigation of individual components (active material, additives, supports) and interaction between these components. They get acquainted with the most important existing problems and drawbacks found in the novel energy devices and measures for their further improvements. Finally, they learn about wider aspects concering the introduction of novel devices (impact on environment and sustainable development, safety aspects, price-performance, development of relevant infrastructure etc.
