Novel in situ and in operando techniques for characterization of interfaces in electrochemical storage systems

Novel in situ and in operando techniques for characterization of interfaces in electrochemical storage systems

Objective

The objective of the project is to develop methodologies for determining in detail the role of interface boundaries and interface layers on transport properties and reactivity in lithium batteries, and to use the knowledge gained to improve performance.
The methods used will be advanced multi-technique in situ characterization combined with computational methods. The findings will be used e.g. in design of artificial Solid Electrolyte Interface (SEI) layers, in optimization of morphology and particle-coating in cathode materials and in improving intra particle ionic mobility across buried interfaces.

In the project the primary goals are to:

1) Understand the important interfaces in an operating battery on an atomic and molecular scale.
2) Characterize the formation and nature of interfaces in situ.
3) Devise methods to control and design interface formation, stability and properties.
4) Prepare ion-conducting membranes, mimetic of the polymeric part of the SEI, in order to study their mechanical and electrochemical properties.
