Bi-annual meeting our roadmap turns one

Celebrating our roadmap turning 1 at our bi-annual meeting

What happens within the battery during operation? Can the degradation that takes place be decreased by using liquid crystal electrolytes? To what extent can computer-based models replace physical experiments? These are questions researchers try to answer, in the BATTERY 2030+ initiative and its projects.

Batteries are hotter than ever in Europe. In BATTERY 2030+ bi-annual conference several speakers contributed to an overview on how we reinvent the way we invent batteries. It clearly requires expertise from all parts of the battery value chain.

Vittorio Pellegrini, Italy, with one foot in the industry and one in academia, talked about the graphene flagship efforts on batteries. Graphene is a fairly new material, it was isolated for the first time as late as 2004. Before graphene can be produced in large quantities at an affordable price the role for it in energy storage and batteries will be limited. However, Vittori Pellegrini means that a pinch of graphene can increase the battery lifetime and capacity substantively.

Pam Thomas from The Faraday Institution gave a short presentation on battery research in UK. The ambition is much alike the one in BATTERY 2030+. And as we all know, it is always interesting to listen to people in the field dealing with the same challenges as you. The research is focused on lithium-ion batteries but also on future chemistries like solid state and how to tackle electrolyte cost and quality, combine atomistic modelling and material synthesis for fundamental understanding of fatigue and degradation, test new materials for extended cycles and find suitable recycling processes - to name a few!

Accurate monitoring of the battery during operation is challenging and needed in order to fully understand the degradation mechanisms in batteries. To reach deeper physical and chemical understanding the use of machine learning, advanced modelling and AI-algorithms is becoming more and more in focus. This was evident listening to the presentations given by the coordinators for the six research groups in BATTERY 2030+. The largest, Big-Map, use a data centric approach to accelerate chemistries with potential to enhance battery performance. A clear ambition is also to set standards for battery research in Europe incorporating a shared battery language; an ontology. Research to hinder dendrite growth in Li-metal batteries​ by using liquid crystal electrolytes is an objective for Hidden. By optimal composition, supported by the use of protecting additives in the electrolyte the batteries has the potential to become self-healing.​ Bat4ever also works with self-healing by developing polymer based so called lonogels, cathod nanoparticels and silicon anods.

Instabat, Sensibat and Spartacus all work with smart sensing technologies and functionalities integrated into a battery cell. The aim is to improve safety, range and life time of batteries for use in cars and other applications. This is carried out by experiments with physical sensors as well as virtual ones. Instabat use-cases are focused at cycling at extreme conditions​ and high-power charging for electric vehicles applications​. Sparatcus overall aim is to find ways to faster charging without negative impact on cycle life, which - we are there again - requires a more profound knowledge about correlation between failure and degradation mechanisms in the battery. Sensor development is a vital part to catch this knowledge.
