Lay Summary (English)

Lead
Lay summary
The grand scientific challenge of this project is in the interdisciplinary field combining interface electrochemistry and material science. The ultimate goal is an improvement in the energy efficiency of electrochemical energy storage devices (batteries) for portable applications by understanding the electrochemical overpotentials at the electrode/electrolyte interface and then by developing better materials.
More specifically, the project is divided into two major tasks aiming at the understanding of and developing new electroactive materials for electrochemical energy storage devices and a supporting task delivering thin layers of these materials, to be used as model interfaces for fundamental studies.
The objective of the first task is the hybridization of a lithium-ion battery and a supercapacitor on the electrode materials’ level. The objective of the second task is the development of novel, environmentally benign electroactive materials by optimizing their structure, morphology, and by using a new electrode binder. The objective of the last task is a good understanding of the kinetics of the lithium ion transfer at the electrodes.
