New publications available

There are two new publications in the Journal of Power Sources available. The first one is authored by my colleague Jörg Illig and deals with modelling the impedance of graphite anodes by means of serial and transmission line models.

The other one is authored by myself. Therein, an extended homogenized porous electrode model is introduced, exploiting the information about the particle size distribution from tomography studies. With this model, the coupling between small and large particles can be reflected, despite the homogenized nature of the model.

Detailed bibliographic information can be found at the publications page.

Novel method to measure the effective conductivity of a battery electrode

My most recent publication in Electrochemistry Communications is now available. Therein, a new method is introduced to measure the effective conductivity of an electrode for lithium-ion batteries. In addition to the conductivity, this method yields also the contact resistance between the electrode coating and the metallic current collector. The great advantage of this method, compared to others is, that it can be applied directly to the identical (disc-shaped) electrodes, that are usually used for electrochemical investigations.

New publications available

Since two weeks ago, two new paper are available online. One about microstructure reconstruction of LiFePO4 cathodes for lithium-ion batteries. The other one is authored by a collegue of mine and focusses on the separation of loss-proceses using impedance spectroscopy. The detailed bibliographical references can be found on the publications page.
