Our group has developed and successfully used an in-situ measurement setup for the study hydrothermal formation of nanoparticles under sub- and supercritical conditions. The presentation introduces details of the experimental setup as well as explaining each step of the data analysis. As an example of one of our experiment some preliminary results of a temperature …

Store investeringer til elektrificering af jernbaner kan muligvis spares ved i stedet at ”batterificere” tog. Teknisk set er batteridrift et interessant alternativ til en fuld elektrificering med køreledninger. Der har i over 100 år været batteridrift i Tyskland – frem til 1995. Det var med gamle, store og tunge blysyrebatterier. Ny batteriteknologi, der er udviklet …

Further elaboration on the equivalent circuits for EIS measurements and how they are linked to the chemical processes. Johan also explained some of the pitfalls of using equivalent circuits to model the impedance response, as it is always possible to construct an equivalent circuit with the right output characteristics, but that might not be a …

Presentations on general electrochemistry such as electrode-electrolyte interfaces and basic electrochemical relations including the Nernst equations and the Butler-Volmer equation. Explaination of the background for equivalent circuit models and how the impedance response looks for these circuits in a Nyquist plot. To give a better understanding of EIS measurements a practical example is shown. General …

The heart of any electric vehicle is a lithium-ion battery pack. The whole battery pack is managed in real time by a Battery Management System (BMS) – an electronic system that controls the battery pack allowing safe and reliable operation. The BMS provides overall management of the battery pack including over and under voltage protection, …
