Battery research occurs across the full value chain, can be oriented towards battery cells, and can be based on competences in chemistry, physics, materials science, modelling, characterisation et cetera. It can also be oriented towards systems where the battery cells are integrated to packs, to be used in different applications. Here, the field relies on knowledge about electronics, electrical engineering, systems-control, modelling at system level, artificial intelligence (AI) and machine learning – just to mention some. Also, research in recycling has become more important and again rely on chemistry, metallurgy, physics and materials science linked to the use of new efficient characterisation tools.
The areas of research advocated by BATTERY 2030+ rely on these cross- and multidisciplinary approaches with a strong wish to integrate other areas of research to enable cross fertilization.
So far, five main research areas have been defined to address the challenge of developing next-generation batteries, with more areas to follow. The research areas oultlined in the roadmap are:
- Materials Acceleration Platform
- Battery Interface Genome
- Smart sensing and self-healing
The proposed research directions are all chemistry-neutral, which means that they can potentially be applied to any battery chemistry, creating an impact on both state-of-the-art and future electrochemical storage systems.
The research actions will span the entire value chain. For example, if sensors, self-healing chemistries, or other smart functionalities are implemented, this will influence not only manufacturability and/or recyclability, but also the development of Battery Management System (BMS) operating protocols, hardware and software.
Manufacturability and recyclability will be considered as two key crosscutting themes. New battery materials, engineered interfaces and smart battery cell architectures will be developed bearing in mind the manufacturability, scalability, recyclability, and life-cycle environmental footprint of the novel technologies.
The proposed research directions should be seen as a starting point for BATTERY 2030+. Flexibility is a key factor for the success of a long-term and large-scale research programme.The BATTERY 2030+ initiative will therefore be open to new research areas identified later on by the European research community.
