LIMG: Artificial Intelligence-Driven High-Fidelity Inverse Design of Solid-State Electrolytes

Project description

AI-driven design of high-performance energy materials

Solid-state electrolytes are crucial for sustainable energy storage, yet their development is hindered by low efficiency and high testing costs. Supported by the Marie Skłodowska-Curie Actions programme, the LIMG project aims to launch a Loop-Locked Intelligent Material Generation platform, an AI-driven system designed to accelerate the discovery of high-performance materials. By using specialised machine learning to simulate lithium movement with high fidelity, the project aims to bypass slow, expensive traditional computations. Additional objectives include building a massive, reusable material database and employing generative AI to design new electrolytes with specific properties. The project’s goal is to revolutionise how we create energy materials, speeding up the transition to low-carbon technologies while training the next generation of leaders in AI-driven science.

Objective

Solid-state electrolytes (SSEs) promise to revolutionize energy storage and carbon-neutral mobility industries, but their low ionic conductivity remains a barrier. Discovery of high-performance SSEs is hindered by a lack of high-quality lithium-diffusion data, unclear structure-property understanding, and the high cost of traditional computational screening. This project aims to build a Loop-Locked Intelligent Material Generation (LIMG) platform by coupling a pre-trained machine learning force field (MLFF) called SO3LR-SSE with advanced generative models. SO3LR-SSE explicitly incorporates non-local and many-body interactions to improve the fidelity of dynamic SSE databases and the transferability across diverse material systems. The project includes four main work packages (WPs 1-4, LIMG platform) plus one for data management, career development, and dissemination. WP1 will develop a high-fidelity, transferable MLFF for SSEs to speed up Li-diffusion dynamics simulations, forming the basis for generating a comprehensive SSE database of ionic conductivities in WP2. WP3 will use ML and the database to accurately predict ionic conductivity and elucidate structure-property relationships. WP4 will focus on inverse SSEs design with clear physical interpretability based on generative models. LIMG is expected to generate a large, reusable dataset and rapidly identify novel candidates across global chemical spaces for experimental follow-up. A planned secondment at TU Berlin will support MLFF development in a collaborative environment. For the fellow, this project will significantly strengthen skills in advanced AI algorithm development, materials design, and interdisciplinary collaboration, strengthening prospects for leadership in AI-driven materials research. LIMG aspires to be widely expanded to material systems, advancing innovative, interpretable, high-fidelity design of new energy materials and accelerating deployment of low-carbon energy storage technologies.
