This article provides a discussion and analysis of several important and increasingly common questions: how battery data are produced, what data analysis techniques are needed, what the existing data analysis tools are and what perspectives on tool development are needed to advance the field of battery science.
Product data collected during production and the entire lifetime of a battery contributes to improving the product development process, the product quality, and its manufacturability. Manufacturing machines are the most important gateway to collecting process data along the battery cell production line.
2. The current status of data and applications in battery manufacturing Battery manufacturing generates data of multiple types and dimensions from front-end electrode manufacturing to mid-section cell assembly, and finally to back-end cell finishing.
Moreover, appreciating the value of data as an asset is critical for unlocking new business models for battery cell manufacturers. The risk of failing to adopt the right digital technologies at the relevant phases of the plant lifecycle can lead to missed opportunities and financial underperformance.
Data-driven methods compared to traditional approaches can effectively enhance the efficiency and quality of battery manufacturing, and reduce production costs, but face challenges such as difficulty in deployment, insufficient generalization, and the inability for online use in the production chain.
