Towards in situ imaging of electrolyte physical and chemical changes in Li-ion batteries
The Lithium conducting electrolyte is a critical component of Li-ion batteries, as it has an important impact on performance and its durability, in particular in case of extreme environmental conditions. At low temperatures, a partial solidification can occur, while high temperatures can promote the degradation of the electrolyte. Using time-of-flight (ToF) neutron radiography, the possibility of imaging such changes in a fully non-invasive manner was demonstrated for the first time.
Versatile and Fast Methodology for Evaluation of Metallic Lithium Negative Battery Electrodes
Evaluating potential electrolyte candidates is typically a lengthy procedure requiring long-term cycling experiments. To speed this process up, we have investigated potentiostatic lithium plating as a potential method for fast electrolyte suitability investigation. The applications of this methodology is not limited to liquid electrolytes, - effects of solid-state electrolytes, coatings, and other modifications can be readily assessed.
Basic course in Electrochemistry (Prof. Dr. Petr Novák, ETHZ)
The basic course in Electrochemistry (given in German) will start in the room HPT C 103 (ETH Campus Hönggerberg) on Monday, September 23, 2019 at 08:45. For further information, please contact PD Dr. Lorenz Gubler, E-mail: Lorenz.Gubler@psi.ch. Download the slides of the lectures here (password-protected): Vorlesung Elektrochemie.
Group Head Aerosol Physics and Optics
Battery Electrodes and Cells
The primary goal is the development of a safe, environmentally benign, and cost effective electrochemical energy storage system with significantly improved specific energy. The research work focuses equally on the scientific background essential for the development of new technologies and on the analysis of ageing and safety relevant aspects of current industrial batteries. The investigated systems include both lithium-ion and post-lithium-ion batteries.
