The high energy density of Li-ion batteries has enabled the introduction of portable electronics in our daily lives, the development of electrical vehicles and is expected to be a critical technology for lifting the intermittency of renewable energy sources. Li-ion transport and local structural changes in electrode and electrolyte materials are decisive for the battery performance. However these processes are often hard to monitor on a microscopic level under realistic operando conditions. In this presentation some of the key challenges of next generation batteries, including solid state batteries and Li-O2 batteries, are brought forward along with the use of operando neutron and X-ray techniques as well as Nuclear Magnetic Resonance to gain more insight in the fundamental processes.

 

Short CV: Marnix Wagemaker completed his MSc in Applied Physics at the Delft University of Technology in 1996. After working as development engineer in computer aided techniques he completed his PhD at the Delft University of Technology on neutron and NMR research of Li-ion battery materials. This was followed by a visiting scholarship at the Department of Materials Science and Engineering of the Massachusetts Institute of Technology (MIT). In 2017 he became head of the section Storage of Electrochemical Energy, the battery research group at the Delft University of Technology and in 2018 he became full professor in Electrochemical Energy storage. The research of Marnix Wagemaker aims at fundamental understanding and improvement of electrochemical energy storage processes in batteries. During the last five years a red line is the development and application of relatively new (operando) experimental approaches including Neutron Depth Profiling, solid state NMR and microbeam diffraction, in many cases combined with (ab-initio) simulations. Current research focusses on the fundamental processes in next generation Li-ion/Na-ion, solid state and Li-air batteries.
