Atomic Configuration for different lithiation levels for SnO

Short Description

Electric cars such as the Tesla Roadster have a high demand for better Li-ion batteries.
Scheme of a Li-ion battery [from Goodenough, J. B., and Park, K.S. ACS. 135.4 (2013): 1167-1176]

The storage capacity is an important property which can enhance the battery life of today's portable devices, like smartphones and notebooks, as well as of electric vehicles. Therefore, we are investigating different electrode materials for Li-ion batteries with the help of advanced simulation tools for nanoscale devices. Tin (Sn), for example, provides a storage capacity for lithium which is more than twice as much as the capacity of the widely used anode material graphite. An analysis of the electron conductance is necessary to ensure that the material characteristics do not limit the charge/discharge process of the battery.

Your task is to customize a pre-designed set of structures for investigation on their electron conductance. This will be done with several simulation tools provided from our group. At the same time you will create your own analysis scripts to study the outputs of the simulations.
