Innovation in electric vehicles and energy storage from renewable sources are two key drivers in the rapid growth of a battery industry that is striving to improve performance of battery systems with great urgency.
Machine learning can help, extracting value from existing data to accelerate the development of new battery materials and formulations, optimise the design of battery packs, and enable more effective battery management systems. The Alchemite™ deep learning software was designed for such complex prediction and optimisation problems, where data is often sparse and noisy.

Machine learning for battery applications
Example projects
Optimising production processes and battery chemistry
In a project with industry and academic partners, Alchemite™ machine learning was applied to optimise the formulation and manufacturing of electrodes for lithium-ion batteries. Conventionally, improvements are identified via trial-and-error, with a large matrix of experiments. Use of Alchemite™ to predict electrode performance focuses such experiment and reduces the development time for new battery chemistries. At the end of the project, the proposed electrodes were manufactured and showed excellent lifecycle and capacity, as predicted.
Data-driven machine learning for battery management
A collaboration between the University of Cambridge, A*STAR and Nanyang Technological University in Singapore, assessed methods for predicting electric vehicle battery states and revealed that a data-driven machine learning model offers the most accurate predictions for State of Charge (SOC) and State of Health (SOH). The project provides a case study for machine learning accurately predicting the health and life of a battery, with the potential for manufacturers to embed these methods into their battery devices, improving in-life service for the consumer.
