Roll to Roll Coating Machine for Lithium Battery Electrode | 3D Demo

This video showcases the TOB-SY300J, a high-precision roll-to-roll transfer coating machine built for lithium-ion battery electrode research and pilot production. Whether you're developing new cathode formulations, optimizing anode structures, or scaling from coin cells to pouch cells, this system delivers production-grade coating quality in a compact lab-adapted platform. ⚙️ Why Coating Precision Defines Electrode Performance: In lithium-ion cells, coating uniformity directly governs capacity, rate capability, and cycle life. Thickness variations as small as a few microns create current distribution hotspots, accelerate localized degradation, and compromise cell safety. The TOB-SY300J eliminates this variability with closed-loop tension control, high-precision comma scraper metering, and a stable three-roll transfer architecture—achieving ±3μm coating accuracy for both NMP-based and aqueous slurry systems. 🔄 Continuous & Intermittent Coating in One Machine: Traditional lab coaters lock you into a single coating mode. The TOB-SY300J changes that. → Continuous Coating — Ideal for uniform full-surface electrode films. Produces consistent, defect-free coatings across the entire substrate width for standard electrode designs. → Intermittent (Gap) Coating — Precisely controls coating length and blank spacing, essential for creating uncoated tab areas and advanced patterned electrode structures. Switching between modes is seamless—no hardware changes, no recalibration, no downtime. 🔧 Key Features That Drive Lab Efficiency: ✅ Three-Roll Transfer Coating Technology: Unlike single-blade or simple comma systems, the three-roll architecture delivers a wider process window, better slurry distribution, and fewer defects (streaking, edge unevenness) across different viscosities and solid contents. ✅ Automatic Tension Control with EPC Web Guiding: Maintains stable substrate movement for aluminum and copper foils as thin as 8μm. Prevents wrinkles, ensures accurate double-sided alignment, and keeps the coating uniformly flat from unwind to rewind. ✅ Dual-Side Hot Air Drying: Top and bottom air blowing ensures uniform solvent evaporation, better film adhesion, and faster drying. Supports both NMP-based and water-based slurries. ✅ PLC Touch Screen Control: Set coating speed, gap, drying temperature, and coating mode from one intuitive interface. Real-time parameter monitoring reduces operator error and improves batch consistency. ✅ Optional NMP Solvent Recovery: For labs working with NMP-based slurries, an optional recovery system captures solvent vapors—reducing emissions, cutting costs, and improving lab safety. 📐 Built for Lab & Pilot Environments: The TOB-SY300J accommodates substrates up to 280mm effective coating width, foil thicknesses from 8–30μm, and slurry viscosities from 2000–12000 mPas. It handles cathode materials (LFP, NMC, LCO, LMO) and anode materials (graphite, silicon-carbon) with equal precision. 📩 Get specifications, optional configurations, or a quotation: 📧 Email: tob.amy@tobmachine.com 🌐 Product Page: https://www.tobmachine.com/roll-to-roll-coating-machine-for-lithium-battery-electrode_p803.html 👍 If this equipment overview supports your research, please Like, Share, and Subscribe for more battery manufacturing solutions. #RollToRollCoating #BatteryElectrode #ElectrodeCoating #LithiumIonBattery #BatteryManufacturing #LabEquipment #BatteryResearch #TOBNewEnergy #TransferCoating #ContinuousCoating #IntermittentCoating #PilotProduction --- 🎵 Music Credit: "Ethereal" by Punch Deck Listen here: https://youtu.be/Tf7Eo3N47_w
