Probing inside a material, at the interface of two different layers, is one thing. Doing this under realistic circumstances, while the materials are active, is another, and it is not so easy. That is exactly what researchers of the MESA+ Institute of the University of Twente would like to achieve, using the special machine they are building. Thanks to a three-‘colour’ X-ray system, they will be able to look at three separate depths. The HAXPES system, for which Dutch Research Council NWO granted a large subsidy of 2.2 million euro, will prove its unique qualities in, for example, the development of new types of batteries for electric mobility and new catalysts for producing green hydrogen.
Daniel Monteiro Cunha has received his doctoral degree by successfully defending his PhD thesis titled 'Self-assembled Vertically Aligned Nanocomposites for Solid-State Batteries'. The external members of his PhD committee were Prof. Judith Driscoll (University of Cambridge) and Prof. Taro Hitosugi (Tokyo Institute of Technology). (10/3/2021)
Materials that turn from isolators into conductors by mechanical stress, could lead to valuable new components in electronics. Unfortunately, this type of materials doesn’t easily match with silicon, the basic material in chip technology. This could change soon: researchers of the University of Twente demonstrate a new way of adding their ‘exotic materials’ to a silicon base. The strain-controlled material could be a valuable new component on chips, and thanks to the ultra thin protective layer that comes from IBM Research, it is now possible to build the switch on top of silicon. The paper ‘Strain-engineered metal-to-insulator transition and orbital polarization in nickelate superlattices integrated on silicon’ is published in Advanced Materials.
A new technology to be used in lithium batteries can make them charge faster. The material graphite that was often used, already had a successor that could not further be improved, was the assumption. Until now, as researchers of the MESA+ Institute of the University of Twente found out that by nanostructuring the material, new ‘paths’ will be created for lithium ions. This makes the battery charge faster, the researchers show in their paper in Journal of Power Sources (‘Enhanced lithiation dynamics in nanostructured Nb18W16O93 anodes, by Rui Xia, Congli Sun,Yang Wang, Daniel Cunha, Hayang Peng, Kangning Zhao, Mark Huijben and André ten Elshof). The researchers demonstrating these results earlier on, stated that NbWO already shows such excellent properties that nanostructuring it beforehand, would have no added value. The UT researchers now demonstrate that nanostructuring indeed has a substantial effect.
The kick-off meeting of the Accumulate research consortium was held on February 13 2020, in which several partners from Eastern Netherlands team up to realize a better, safer and more sustainable application of batteries. The project partners Contour Advanced Systems BV, Van Raam, BREKR, Hencon, DNV GL, Twente Safety Campus and University of Twente will collaborate to explore the production of next-generation batteries in the Netherlands. This will enable the development of form-free, modular and safer battery packs for several (niche) markets such as electric motorcycles, adapted bikes and heavy duty vehicles. Special attention will be given to innovative fire extinguishing systems for storage, as well smarter reuse and recycling. The Accumulate project is partially financed by OP Oost, the subsidy program for companies and knowledge institutes in Overijssel and Gelderland, which is part of the European Regional Development Fund (EFRO).

The University of Twente has become a partner of the Alistore European Research Institute. Within this prestigious European network in the field of battery research, top-level research groups work in close collaboration to develop the batteries of the future. The Alistore European Research Institute is the largest research network in the field of battery research in Europe. The network consists of 23 top groups that are engaged in cutting-edge fundamental research in the field of batteries and the materials involved in making batteries. Alistore is the point of contact for large European research institutes, coordinates research for the business community and is committed to obtaining financing for battery research. MESA+ researcher Mark Huijben, who focuses on conducting fundamental research into optimizing new and existing materials for batteries, sees this as validation of his team's work. “Here in Twente we are relatively new to the field of battery research, but we are making huge strides in our development. For me, joining Alistore is a recognition of our work." (1/9/2018)
