Circular value chains, driven by sustainability goals and resource efficiency, are now central in industrial strategies. Simultaneously, digital technologies transform business models and accelerate the shift towards circular economies. This paper explores circular material flow for the electrification of the vehicle fleet, focusing on the Lithium-ion battery value chain. In the paper, a conceptual model integrating digitalization is developed and evaluated to enhance efficiency and product innovation. The paper reviews the lithium-ion battery value chain literature and investigates digitalization potentials for circular business models. A conceptual model is presented in this study to represent the intricate relationship between each stage of the value chain and the concept of circularity while considering the carbon footprint and complexities associated with the implementation of digitalization.
