Predicting properties or classes of materials based on minimal input information, such as a chemical formula, can be a useful first step to identify which materials are promising candidates before investing resources. This is particularly desirable when working with complex compounds containing a large variety of elements, such as materials for battery applications. In this paper we show how to classify battery compounds into either charge or discharge formulas, or identify suitable anode or cathode materials, based exclusively on the chemical formulas of materials available in online repositories. Without any structural information, we train high-performing classifiers that can be used to rapidly screen hypothetical materials and assign potential applications. The models are applied to a total of 471 materials from the literature, and deliver a 96% success rate over 80% probability. These methods are general and the workflow can be applied to any complex crystalline materials to predict end-uses in advance of synthesis or simulation, opening up the opportunity for machine learning to use used for research planning, in addition to prediction or inference.Computational resources for this project have been supplied by the National Computational Infrastructure (NCI) national facility under Grant p00.10en© 2024 The Author(s)AnodeBatteriesCathodeChargeClassificationDischargeMachine learning202510.1016/j.commatsci.2024.11334485203414055
