Short Description

Renewable energies produced through solar and wind power will become true alternatives to fossil fuels if they do not need to be consumed instantaneously, but can be stored first and then used when really needed. This will only be possible if the capacity of the currently manufactured storage systems rapidly improves. Lithium-ion batteries, which are characterized by the transfer of Li atoms between a graphite anode and a metal-oxide cathode, are good candidates as next generation storage units, provided that new cathode/anode materials with higher efficiency can be designed. An accurate physics-based model of Li-ion batteries can greatly support the experimental development of such devices and shed some light on what is happening internally.

Standard 1-D simulation models, as popularized in the mid 90's, are computationally very efficient to fulfill this task, but do not capture the shape of the electrode active components. The goal of this project is therefore to implement a 2-D model based on the finite element method that can take realistic electrode morphologies as input parameters.
