MMH.20.001 – BatteryNL – Next Generation Batteries based on Understanding of Materials Interfaces

Route: Materials - Made in Holland

Cluster question: 026 How can we store, convert, and transport energy efficiently?

The urgency posed by global warming to transform our fossil fuel-dependent society into one based on renewable energy sources creates grand technological challenges, one of them being renewable energy storage for mobility and intermittent wind and solar electricity. Batteries are widely seen as key technology for electrification of transport, and for future medium-scale electricity storage. However, this requires a huge leap in battery developments. This proposal targets next generation battery chemistries that can fulfil these requirements, and addresses the main hurdle to their implementation: insight into and control over parasitic reactions that presently cause underperformance, degradation and safety issues. Studying these reactions at the interface between electrolyte and electrode is a great challenge, due to the inherent heterogeneity of real battery systems, and the advanced characterization techniques that are required. Our approach will be the creation of 2D and 3D model interfaces that will be systematically studied with state-of-the art and recently developed new (in-situ/operando) analytical tools. This systematic approach will provide the required understanding of charge transfer and chemical processes at the electrode-electrolyte interfaces. The challenging scientific goal is to achieve full control over these interface processes, using rational interface material strategies, where the technological challenge is to translate these into scalable fabrication methods. Additionally, evaluation of sociological, technological and economic aspects is necessary to realize large scale integration of batteries in our society; together the aim of this consortium proposal. The consortium comprises multidisciplinary team combining the complementary expertise’s, comprehensively covering the value chain and disciplines battery science and technology. Bringing these strengths together to form a strong battery research network is the opportunity to gain momentum in battery technology in the Netherlands.
