Pouch cell lithium ion batteries are used in the field of electric vehicles and solar home storage. This paper shows a measurement setup for the three-dimensional measurement of thickness change on a flat 6.7mm thick pouch cell using a white light interferometer. With a measuring field of 7.05mm diameter the resulting 3D thickness change record contains 226000 3D readings. The measuring points have a lateral distance of 13.1μm. The repeatability of the measurement is 312.8nm for the individual values and 64.1nm for the average value. In addition, this paper shows how the storage capacity of this pouch cell drops over 30 charge cycles.}, language = {en} } @article{BohnBayerStolzetal., author = {Bohn, Gunther and Bayer, Sven and Stolz, M. and Ackva, Ansgar and Arndt, Bernhard}, title = {Lifetime Simulation of Rechargeable Batteries for Solar Powered Fishing Lights}, series = {Applied mechanics and materials}, volume = {848}, journal = {Applied mechanics and materials}, issn = {1662-7482}, doi = {10.4028/www.scientific.net/AMM.848.115}, pages = {115 -- 118}, language = {en} } @article{BayerSchreibmannAckvaetal., author = {Bayer, Sven and Schreibmann, Vitaliy and Ackva, Ansgar and Balzer, Arndt and Braun, Peter}, title = {PedElEc: Towards a Better Understanding of Ageing Processes of E-Bike Batteries}, series = {Applied mechanics and materials}, volume = {848}, journal = {Applied mechanics and materials}, issn = {1662-7482}, doi = {10.4028/www.scientific.net/AMM.848.119}, pages = {119 -- 122}, language = {en} }
