Electrodes for Lithium ion cells

Objective of the research on Lithium-Ion-Batteries is the optimisation of electrodes which can be used in batteries for electric vehicles, with respect to energy and power density, life time and used materials including for example novel active components, additives or binder systems. These materials are delivered by research or industry partners or are commercially available.

At ZBT battery electrodes in laboratory scale can be prepared and analysed. The physically characterisation includes optical 3-D-measurements, determination of water content, identification of electrical resistance and investigation of adherence on the current collector foil.

Initial electro-chemical investigations will be performed in so called T-Cells. Electrodes of larger area can be analysed in self-made Pouch-Cells, comprising only little number of electrode pairs. Characterisation includes cyclovoltammetrie, galvanostatic cycling and impedance spectroscopy. Half cells with 3-electrode-assembly (working electrode, counter electrode and reference electrode) as well as full cells consisting of two working electrodes and optional a reference electrode can be operated.
