Accelerated discovery of battery interfaces and materials
At the heart of inventing the batteries of the future lies the discovery of high-performance materials and components that enable the creation of batteries with higher energy and power.
Research project – BIG-MAP, coordinated by DTU.
BATTERY 2030+ advocates the development of a battery Materials Acceleration Platform (MAP) to reinvent the way we perform battery materials research today. This can be done by combining powerful approaches from high-throughput automated synthesis and characterisation, materials and interface simulations, autonomous data analysis and data mining, as well as AI and machine learning.
Interfaces are arguably the least understood aspect of the battery, even though most of the critical battery reactions occur there, reactions such as dendrite formation, solid electrolyte interphase (SEI) formation, and cathode electrolyte interface (CEI) formation. Building on MAP, BATTERY 2030+ proposes to develop a Battery Interface Genome (BIG) that will establish a new basis for understanding the interfacial processes that govern the operation and functioning of every battery. The accelerated design of battery materials requires the detailed understanding and tailoring of the mechanisms governing interface formation and evolution.
This involves both studying the mechanisms of ion transport through interfaces and, even more challenging, visualising the role of the electron in the interfacial reactions. These processes determine whether the ultra-high-performance batteries developed will be safe to operate and exhibit the long lifetimes that are necessary.
A central aspect will be the development of a shared European data infrastructure capable of performing the autonomous acquisition, handling, and analysis of data from all domains of the battery development cycle. Novel AI-based tools and physical models will utilise the large amounts of data gathered, with a strong emphasis on battery materials and interfaces. The data generated across different length and time scales, using a wide range of complementary approaches, including numerical simulation, autonomous high-throughput material synthesis and characterisation, in operando experiments, and device-level testing, will all contribute to new material and battery cell development.
Integrating these two research areas, BIG and MAP, will transform the way we understand and discover new battery materials. Theme I will deliver a transformative increase in the pace of new discoveries for engineering and more developing safer, longer-lived, and sustainable ultra-high-performance batteries.
