AI’s Role in Revolutionizing Battery Technology and Materials Design

Summary

The video, introduced by Dr. James Le Houx from the University of Greenwich and a Fellow of the Faraday Institution, explores how Artificial Intelligence (AI) is revolutionizing battery technology across multiple scientific scales. Dr. Le Houx draws a parallel to Humphry Davy and Michael Faraday, who transformed electricity into a tool for discovery, asserting AI is undergoing a similar transition, poised to revolutionize battery technology. Despite their unassuming appearance, batteries are vital for modern society, underpinning national infrastructure, aviation, medical equipment, data centers, and the global transition to a low-carbon economy. The inherent microscopic complexity of batteries, involving intricate interactions of physics, chemistry, and mechanics (such as ion shuttling, particle degradation, and film growth), presents a formidable challenge that AI is uniquely positioned to “unpick” and understand. The lecture series subsequently delves into four key scales: atomic, microstructure, cell/pack, and grid.

Professor Aron Walsh from Imperial College London then focuses on AI at the atomic scale for materials design. He highlights that centuries of modern chemistry, encompassing millions of published papers, chemical compositions, and characterized structures, have generated a data volume far beyond human processing capabilities. AI addresses this by encoding chemical information into numerical “vectors” or “fingerprints,” enabling it to identify underlying patterns and make predictive discoveries, much like Mendeleev did with the periodic table. The immense “chemical space” of possible materials (exceeding 10^100 combinations, more than atoms in the known universe) makes traditional trial-and-error inefficient. Generative AI is emerging as a “digital alchemist,” capable of rapidly generating novel material structures from simple text prompts, promising to accelerate the development of sustainable, solid-state batteries with enhanced properties and significantly reduce development timelines from decades to years.

Dr. Mona Faraji Niri from the University of Warwick shifts the focus to AI for battery diagnostics at the system scale. She explains that batteries inherently degrade, “getting tired” even before their first use, due to mechanical stresses, particle cracking, and dendrite formation during charge and discharge cycles. This degradation is influenced by a complex interplay of factors including user habits, specific battery chemistry and format, manufacturing processes, and environmental conditions (temperature, humidity, storage). Addressing critical “million-dollar questions” about battery lifespan and slowing degradation is paramount for a wide range of stakeholders, from electric vehicle owners to manufacturers and insurers. Given the vast scale of battery deployment (e.g., an estimated 10 billion 18650-sized cells needed annually for UK mobility by 2035), AI acts as a “forensic investigator.” By analyzing “gazillion data points” from multi-modal sources (voltage, current, temperature signals, and microstructural images), AI technologies like machine learning and deep learning can identify subtle patterns, predict a battery’s Remaining Useful Life (RUL), and even incorporate physics-informed approaches to enhance accuracy and generalizability, enabling proactive maintenance and improved design.

Finally, Dr. Sam Cooper, also from Imperial College, elaborates on the critical microstructure scale, which bridges the atomic design of materials with the macro-scale performance of devices. Microstructure, encompassing pores, particles, phases, and interfaces at the nanoscale to micron scale, is complex and emerges indirectly from manufacturing processes, making it difficult to predict or control. AI is revolutionizing this by enabling rapid and accurate characterization of these internal structures, even generating detailed 3D representations from single 2D images, thus accelerating analysis workflows. This capability extends to designing optimal microstructures through iterative optimization loops, allowing researchers to explore how manufacturing parameters influence material properties and battery performance. The advancements in AI, particularly in agentic models that can actively interact with robotic labs, are transforming materials science. These AI co-scientists can automate routine tasks, navigate vast combinatorial material spaces, and orchestrate complex experimental campaigns, making the previously invisible and intractable aspects of battery design and degradation visible, designable, and controllable for a more sustainable energy future.

Description

Batteries power almost everything in modern life but for 200 years, building a better one has meant slow, expensive trial and error. That’s changing.

In this Royal Institution event, in collaboration with the Faraday Institution, three leading scientists reveal how artificial intelligence is transforming battery science at every scale. Exploring the atoms that make up a material, the microscopic structure of an electrode and the algorithms predicting how long your battery will actually last.

🔬 Aaron Walsh (CuspAI / Imperial College London) explains how AI acts as a “digital alchemist” — simulating billions of possible crystal structures to discover battery materials that don’t exist yet.

⚙️ Sam Cooper (Imperial College London) reveals how machine learning is used to reverse-engineer the perfect internal “microstructure” of a battery electrode — the missing link between atoms and real-world performance.

📊 Mona Faraji Niri (WMG, University of Warwick) shows how AI acts as a forensic investigator, decoding sensor data to detect hidden faults and predict a battery’s remaining lifespan — sometimes before it’s even been used.

Chaired by Dr James Le Houx (University of Greenwich / Faraday Institution), this talk traces a direct line from Humphry Davy and Michael Faraday’s first electrochemical experiments — performed in this very lecture theatre 200 years ago — to the AI-powered battery labs of today.

This event was filmed at the Royal Institution on 15 June 2026.
