Automated Solid-State Battery Processing Platform
(Laboratory Scale + Automated Pilot Scale)
Powered by high-level whole-line coordination and intelligent supervisory control, this platform supports fully automated processing across solvent-free dry, traditional wet, and dry-wet hybrid routes, enabling stable fabrication and process validation for high-capacity (up to 30 Ah) all-solid-state pouch cells.
Integrated with automated intra-glovebox material handling and a closed-loop solvent condensation/concentration system for coating and drying, the platform breaks through conventional laboratory bottlenecks—such as batch inconsistency, scaling difficulties, and slow trial-and-error cycles. Built around continuous automation, it establishes a reliable, reliable scale-up approach to accelerate lab-to-pilot translation and support process transfer from lab to pilot scale.
Application Cases & Typical Configurations
Automated Wet Solid-State Battery Fabrication Line
Enables continuous automated operations from slurry preparation to pouch cell encapsulation. Features end-to-end inert atmosphere containment and comprehensive digital parameter traceability, ideally suited for sulfide chemistry scale-up and process window calibration.
Intra-Glovebox Automated Transfer & Stacking System
Executes electrode sheet transfer, high-precision alignment, Z-stacking, and transfer printing within interconnected multi-chamber gloveboxes. Zero exposure to ambient air eliminates batch cross-contamination and interfacial moisture degradation inherent in manual transfers.
Closed-Loop Solvent Recovery System for Wet Coating
Captures and purifies exhaust vapors from coating drying ovens via dual-stage condensation and concentration. Delivers centralized recovery of hazardous organic solvents, balancing strict environmental compliance with operating cost savings.
"Process-to-Test" Closed-Loop Quality Control Architecture
Across every critical fabrication milestone, the production line seamlessly couples with IEST’s industry-standard characterization instruments—including In-situ Swelling Analyzers (SWE), Powder Resistivity & Compaction Density Systems (PRCD), and the Multi-dimensional Solid-State Electrolyte Testing System (SEMS)—delivering comprehensive, closed-loop quality control from raw precursor powders to finished pouch cells.

FAQs
Depending on your development stage, we recommend the following setups:
- Lab-scale R&D: Start with individual tools (mixer, film former, die cutter) and mold-cell testing.
- Process validation: Add the adhesive-frame, sealing, and press-locking tools to complete cell assembly.
- Pilot-scale development: Consider the turnkey automated platform with glovebox transfer and solvent recovery.
Several tools are designed for protected-atmosphere use. For example, the multi-roller film former has a compact body that fits inside a glovebox, and the turnkey platform includes automatic transfer inside the glovebox. Please tell us your electrolyte system so we can confirm the configuration.
The line supports multilayer ASSB pouch cells with capacities up to 30 Ah (standard pilot formats up to 100 × 100 mm, 1–10 Ah) as well as standardized coin cells for rapid material screening. Line scalability bridges lab-scale R&D (100 mL batch processing) to pilot demonstration throughputs exceeding > 1 m/min continuous roll-to-roll calendering.
Yes. The platform supports dry, wet and hybrid routes, with optional atmosphere protection.
IEST Instruments delivers end-to-end pilot line solutions for all-solid-state battery (ASSB) research, development, and scalable pilot fabrication. The platform supports dry, wet, and hybrid solid-state battery processing routes—integrating raw electrolyte synthesis, resonant acoustic mixing, solvent-free electrode fibrillation, ultra-precision calendering, automated pouch cell assembly, and proprietary in-situ characterization into a unified, modular pilot line.
For highly reactive sulfide (e.g., Li₆PS₅Cl) and halide chemistries, IEST provides full glovebox-integrated pilot line solutions. The entire processing environment operates under continuous argon (Ar) or dry air atmosphere with dew point control down to ≤ −50°C to −70°C, preventing toxic H₂S gas generation and active material hydrolysis via sealed automated intra-glovebox transfer modules.
Unlike conventional processing line suppliers, IEST bridges process equipment directly with electrochemical and mechanical evaluation. The pilot line interfaces seamlessly with IEST's solid electrolyte high-pressure resistivity systems, powder compaction analyzers, and in-situ cell swelling/stack-pressure monitors to deliver closed-loop quality control from powder to packaged cell. See our Solid-State Battery Testing Solutions.
Yes. Each equipment is available individually, and can be integrated into a line later.
