The integration of intelligent digital technologies and data management tools into manufacturing and industrial processes is the main pillar of the Industry 4.0 concept, which promotes the use of new technologies such as big data analytics, blockchain and the Internet of Things (IoT), as well as Virtual Reality (VR), Augmented Reality (AR) and Mixed Reality (MR). VR, MR and AR are immersive technologies, since they create a simulated environment that the user can interact with in a way that feels real. VR is fully immersive, creates a 3D computer-generated environment and generally uses a headset, thus making it a compelling alternative for gaming and training applications . On the other hand, AR allows users to keep seeing the real environment, but overlies virtual elements, and MR combines and allows real and virtual environments to coexist, with the user interacting with both of them at the same time . MR offers spatial flexibility for interacting with virtual objects in real time in a more natural way, and is the only technology that frees up hands, which can be particularly useful in situations where users need to keep their hands free for other tasks . Thanks to their unique properties, immersive technologies become outstanding alternatives for a wide range of applications, including manufacturing and assembly, where they can be used to improve the efficiency and accuracy of industrial processes with real-time guidance and assistance; customer service and sales, since they can provide customers with product information and support in real time to increase sales; or Education and training, since they can provide a more engaging and effective learning experience than traditional methods . Additionally, thanks to the development of immersive devices such as MR glasses, data collection and access have become more pervasive and accessible. Interconnected computers, smart devices and intelligent machines communicate with each other and can reduce the human activity while automating and facilitating data flow management . This revolution is also changing the way we work, by redefining tasks. Digitization is speeding up research, increasing efficiency and productivity, as well as quality and customization . In battery cell manufacturing, integrating new technologies and artificial AI can facilitate predictive maintenance and the optimization of production processes. Overall, Industry 4.0 gives the promise to revolutionize the way battery cells are produced and used, leading to a more sustainable and efficient energy future, but several challenges still remain.
