Today, I was invited to participate in the visit of Euler battery factory. In fact, as an editor in the technical field, I have also visited many battery factories of all sizes, such as Buick's activities, which let me know from beginning to end what process a piece of battery cells go through to become monomer, module and battery (relevant articles click here); Another example is Nissan's activities, which let me understand how small-scale laboratories and trial assembly workshops work (relevant articles click here). These activities have benefited me a lot. However, this Euler's activity made me understand another key issue in battery production - how to make battery cells.
