Current collectors in focus of Li-Ion battery development at ZBT<\/h2>\n
\n

Micro-structured power collectors were the main focus of work in a now completed project. The findings are being incorporated into innovative approaches to the development of three-dimensional current collectors.<\/p>\n<\/div>\n

Together with fem from Schw\u00e4bisch-Gm\u00fcnd we have completed the project “Flexible lithium-ion cells with microstructured current collectors to increase flexibility, adhesion and volumetric energy density”. Different methods for structuring current collectors based on established processes in the field of metal processing or metal deposition were investigated. On the battery side, influences of the process during the application of the active material, but also influences of the used binder with regard to the above mentioned objectives were included in the investigations.<\/p>\n

Two research centres were involved in the project: fem (Forschungsinstitut Edelmetalle + Metallchemie) and ZBT (Zentrum f\u00fcr Brennstoffzellen-Technik) from Duisburg. The fem investigated different structuring possibilities and was responsible for the structural elucidation of the modified current collectors and electrodes. ZBT took over the electrode and cell manufacturing, the electrochemical characterisation of the produced cells and the mechanical test of pouch cells. The results are summarised in a comprehensive final report, which will be published by the TIB Hannover and the member association (German). A short summary of the results can be downloaded (german):<\/p>\n
