Lead Intelligent Equipment (hereafter referred to as LEAD) has recently delivered multiple sets of dry mixing and coating systems designed for large-scale solid-state battery production to several leading domestic and international battery manufacturers, automotive OEMs, and emerging solid-state battery enterprises. The successful delivery signifies broad recognition from top-tier customers and further consolidates LEAD’s leading position in solid-state battery manufacturing equipment.
As a global leader in new energy intelligent manufacturing solutions, LEAD is advancing the full value chain of solid-state battery production—focusing on key processes such as dry electrode preparation, solid electrolyte film formation, cell stacking, frame fabrication, densification, and prelithiation. The equipment delivered in this phase includes mass-production models of integrated dry mixing and coating systems for both anode and cathode manufacturing, covering the entire process flow from controlled feeding and film formation to thinning, current collector compounding, and in-line quality inspection.
The system achieves a mechanical speed of up to 100 meters per minute, meeting production requirements of 5–8 GWh per line, with film widths up to 1000 mm and thicknesses ranging from 40 to 300 μm. It supports efficient production of 2–6 dry electrode strips simultaneously, providing comprehensive compatibility for large-scale manufacturing environments.
Precision, Stability, and Versatility
Driving Industrial Upgrades
- Ensures uniform feeding and micron-level stability in both web width direction and operational movement, securing coating consistency and high-precision processing from the source.
- Equipped with an adaptive cutting system with micron-level blade-to-roller precision, ensuring clean and damage-free film cutting.
- Compatible with a wide range of electrode materials—including graphite, silicon-carbon for anodes and NCM, LFP, and all-solid-state materials for cathodes—with automatic width adjustment to flexibly accommodate various battery specifications, significantly improving manufacturing adaptability.
To enhance the cost efficiency and industrial scalability of solid-state batteries, LEAD continues to uphold its commitment to green, low-consumption manufacturing. Through technological innovation and process optimization, the company has achieved substantial reductions in both energy consumption and overall production cost—marking a key step toward accelerating the industrialization of solid-state batteries.
Precision Temperature Control
Setting a New Benchmark in Energy Efficiency
- To address the challenges of high energy consumption and unstable temperature control in traditional heating methods, LEAD has developed the industry’s first variable-diameter uniform electric heating system for rollers. This innovation minimizes roller gap deformation caused by heating and mechanical stress, reducing energy consumption by 60% compared with equivalent oil-heating systems.
- The powder fibrillation process adopts a three-stage temperature control system that relies solely on plant cooling water, eliminating the need for a mold temperature control unit and cutting energy use by approximately 50%.
- Each roller is independently temperature-controlled, enhancing coating precision and roller rigidity while simultaneously lowering production energy consumption and improving workshop cleanliness and maintenance convenience.
End-to-End Process Optimization
Delivering Stable, High-Quality Output
LEAD’s system employs multi-dimensional powder mixing and cutting, anti-agglomeration sieving, and dynamic pre-mixing to maintain closed-loop control at the coating stage, ensuring exceptional uniformity in areal density. The edge-trimming recovery and feedback mechanism reduces material waste during high-intensity mixing and incorporates negative-pressure dust control to minimize environmental pollution. Meanwhile, real-time monitoring of the roller gap enables ±1 μm precision automatic adjustment, ensuring dynamic balance across wide-width rollers.
Production validation has demonstrated that LEAD’s dry mixing and coating system reduces energy consumption by over 35% and cuts total material and manufacturing costs by more than 15%. Notably, the system not only aligns precisely with solid-state battery production requirements but is also forward-compatible with conventional liquid battery manufacturing—enabling dual-mode flexible production. This provides manufacturers with strong assurance of reduced equipment investment and higher capacity utilization during technology transition periods.
As one of the few equipment providers worldwide capable of delivering turnkey lithium battery production lines, LEAD has taken the lead in unlocking the entire equipment process chain for solid-state battery mass production, establishing a technology matrix with 100% independent intellectual property rights. Recently, LEAD has successfully delivered key solid-state battery production systems, including dry electrode coating, composite transfer, electrode frame printing, high-speed stacking, and large-scale cold/hot pressing and formation equipment, along with complete supporting solutions. The company has also signed strategic cooperation agreements with several leading materials enterprises to jointly advance solid electrolyte research and material validation at the equipment level—accelerating the industrialization of solid-state battery technology.
