TOB Mass Cylindrical Cell Production Line: The Drive for Large-Scale Production
● Fast Technology Group:
（1）Many-tab laser welding (120 pcs/min, yield ≥99.3%).
（2）Baking energy use ≤0.8 kWh/Ah (waste heat recovery setup).
● Deep Cost Down Design:
（1）Electrode cutting use rate ≥95% (AI layout better plan).
（2）Local gear rate ≥80% (key parts as Japanese/German brands).
● Ready for Next Tech:
（1）Kept link for dry electrode path (powder direct coating speed ≥20 m/min).
（2）Works with sodium battery liquid change steps.
● Factory Planning: Establishing a Highly Stable Production Foundation.
(1) Develop battery production capacity targets based on market demand and corporate strategic planning. This provides a quantitative basis for the subsequent design of transportation lines, cleanrooms, and power distribution systems.
(2) Integrate battery capacity design with production workshop layout to engineer material transport systems, ensuring efficient intra-line material flow.
(3) During battery production, the electrolyte filling process and cell encapsulation process demand extremely precise humidity control. Excessive humidity in the working environment can lead to severe consequences such as cell swelling and performance degradation. Therefore, constructing high-performance drying rooms is imperative.
(4) To ensure stable cylindrical cell production line operations, design a secure, reliable, and energy-efficient power distribution system based on total factory capacity and the electrical demands of all systems and equipment. This prevents production disruptions caused by power supply fluctuations.
● Equipment Customization: Focusing on Core Process Capacity Upgrades.
Tailored for the process characteristics of large-format 4680 cylindrical batteries, core equipment with enhanced adaptability and higher throughput is customized. Examples include: customized electrode coating machines and winding machines designed for large 4680 battery electrodes.
● Installation and Commissioning: Ensuring Dual Compliance with Capacity and Efficiency Targets.
Installation and commissioning serve as the critical link between equipment and production. Through 270 days of systematic debugging, the objectives of “stable equipment operation, production capacity attainment, and efficiency compliance” are achieved.
● Battery Manufacturing Technology Delivery
The core of battery manufacturing technology delivery is "technology transfer" and "skills training." Through systematic training, ensure that the local battery factory team has the ability to debug the equipment of cylindrical cell production line, battery equipment operation process, and battery process flows optimizing.
Core enablers of technological implementation
Actionable insights from planning to execution
● Process guarantee: Closed-loop flattening temperature control (±2°C) and laser cleaning to remove the electrode burrs.
● Equipment design: Water-cooled flattening head, infrared temperature real-time monitoring.
● Data traceability: The flattening pressure and temperature curve of each battery are bound to the MES system.
