The increasing demand for renewable resources in the electric grid requires the deployment of energy storage systems. Flow batteries and lithium-ion batteries, which are advanced energy storage technologies suitable for stationary applications, are undergoing rapid development to mitigate the adverse environmental impact of conventional, non-renewable energy resources. However, the inherent chemical toxicity associated with the battery production is not well recognized, and safer alternative materials must be identified. In this study, we perform a chemical hazard assessment, based on comprehensive battery production data, to evaluate the human health and environmental impacts of the primary materials that make up key battery components including electrodes and electrolytes, but also the intermediate processing materials needed for battery manufacturing. In total, six battery technologies with different chemistry combinations are investigated, and the relative performance of those batteries are compared. The results identify materials of high toxicity concern and specific hazard endpoints.
