Aging Mechanisms and Lifetime Prediction of Batteries
Disruptive Battery Technologies and Innovation
Lithium ion battery technology has enabled revolutions in consumer electronics. Smartphones and tablets could not deliver expected performances without the introduction of Lithium ion battery cells with high energy density. Following this breakthrough in mobile electronics, the electrification is the next sector being transferred by enabling battery technology.
This course expands on the design, construction, and ageing of lithium ion cells. The study continues into the material costs and takes a closer look at just why (or why not) this technology is considered disruptive. Additionally topics include the core concepts of Clayton Christensen’s acclaimed book “The Innovator’s Dilemma”, start-up business models, and application specific designs of lithium ion chemistries.

Seminar Batteries, Storage Systems, Fuel Cells and Power Generators
An essential but often overlooked key to effective engineering is the communication of data and information. Each student will research information on one of the topics listed below. The focus will be on the process of information collection, evaluation, and preparation for presentation and technical writing in the scientific and engineering community. The seminar is held in English. In a fully de-carbonized system, which is planned to be reached in 2050, large-scale energy storage will need to be deployed; likewise for the electrification of transportation. With rapidly decreasing costs per kWh and extended calendar life, lithium ion technologies are poised to be relevant in energy storage for electronics, automotive, and grid applications for a long time. This course will allow you to better familiarize yourself with the inner workings of, design, and applications for this technology. Previous knowledge (e.g. Lecture Energy storage technologies) can be helpful but is not necessary. The first two introduction sessions will focus on the techniques of good presentation style. Then each student will probe the presentation with a research associate followed by a content oriented discussion and a detailed feedback on the effectiveness of the presentation. An assigned research associate can guide and supervise the presentation development. The institute can provide basic literature. Further and more detailed information on each topic has to be gathered through own research (literature, contact to manufacturer and/or customers). You have passed the Seminar when you fulfil the following requirements: . Attendance of the first two instructional classes . Regular and active participation in the seminar (>65% attendance) . Presented a practice talk for your research assistant . Prepared and presented your research topic in duration of 30min . Preparation of a paper (at least 3 full pages) .
