Storage of renewable energy is essential in order to create a new sustainable energy economy e.g. directly as electricity in a Li-battery or indirectly as hydrogen in a solid state metal hydride.1 Batteries are rechargeable but have moderate life time and limited energy storage capacity. Metal borohydrides can store considerable amounts of energy as hydrogen …

The search for novel crystalline materials for use as electrodes in battery materials is a lengthy and costly process. There is a great need for a fast evaluation tool to supplement already existing experimental and theoretical methods. In this talk, the procrystal analysis is introduced as a fast technique for pointing out promising candidates for …

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 …
