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, …

Li-ion microbatteries may fill a nieche of applications in compact devices, if they can be manufactured on-location in circuits, or in packages with compact dimensions, and with long life expectancies. The methods of fabrications involve depositions of thin films (electrodes and electrolytes), contacting, and packaging. So far, the development of suitable sputter targets for deposition …
