报告摘要

Lithium-ion batteries have become one of the most promising sources for accelerating the development of transportation electrification, where effective electrode manufacturing plays a key role in determining battery performance. Due to the highly complicated process and strongly coupled interdependencies of electrode production, a data-science solution that can analyse feature variables within manufacturing chain and achieve reliable prediction is urgently needed. This work proposes two feasible data-science solutions, through using interpretable machine learning techniques, for effectively quantifying the importance and correlations of battery manufacturing features and their effects on the predictions of electrode properties. Illustrative results demonstrate that the proposed data-science frameworks not only achieve the reliable predictions of electrode properties but also leads to the effective quantification of both manufacturing feature importance and correlations. This is the first time to design the systematic data-driven frameworks for directly quantifying battery production feature importance and correlations by various evaluation criteria, paving a promising solution to reduce model dimension and conduct efficient sensitivity analysis of battery manufacturing.
