21 Inside the Factory That Makes Lithium-Ion Batteries for Electric Vehicles

Step inside a modern manufacturing facility where lithium-ion batteries for electric vehicles are produced with extreme precision and control. This documentary-style video takes you deep inside the factory to reveal every critical stage of the Factory process, from raw material handling to finished battery packs ready for shipment.
You’ll witness how cathode and anode materials are mixed, coated, dried, and prepared under strict industrial standards. The Factory process continues inside ultra-low-humidity dry rooms, where battery cells are carefully assembled, filled with electrolyte, and permanently sealed to ensure long-term performance and safety.
As the production line moves forward, the Factory process enters formation charging and aging, where each cell is activated, stabilized, and tested for capacity, voltage, and reliability. Only cells that meet exact specifications move on to module assembly and final packaging.
This video captures the Factory process using real industrial equipment, real materials, and natural factory sounds—no narration, no subtitles, and no visual effects. Every scene reflects the scale, discipline, and automation behind modern battery manufacturing.
From warehouse storage to outbound logistics, the Factory process never stops—powering the electric vehicles that shape the future of transportation.
