Polymer electrolytes

Many forms of energy carrier exist of which polymer-Lithium batteries are widely used in our modern society. In order to optimize these batteries we study a variety of highly promising polymer electrolytes containing Lithium ions. Employing Quasi-Elastic Neutron Scattering, Dielectric spectroscopy and MD simulations the Li - trajectories can be observed which is a unique way to enlighten the microscopic aspects of charging and discharging of batteries.
