Professional solid-state battery pilot line solution services. TOBGROUP ensures smooth transition from pilot line to mass production line with expert guidance. We offer tailored equipment, facility design, and staff training for successful pilot production.
TOBGROUP focuses on the industrialization bottlenecks of solid-state batteries (SSB), offering a full-stack solid-state battery pilot line solution. We deeply integrate solid electrolyte integration, interface modification, and dry electrode technology, providing a critical bridge from lab line to mass production for sulfide/oxide/polymer systems, overcoming the three core challenges: ionic conductivity, interface contact, and scalable manufacturing.

TOB Solid-State Battery Pilot Line: Bridging Lab to Mass Production
● Dedicated All-Solid-State Process Platform
(1) Integrated continuous dry electrode film forming system (Powder dispersion → Mixing → Hot pressing), avoiding solvent erosion of solid electrolytes.
(2) Utilizes multi-stage hot pressing interface fusion technology (Pressure 5–100MPa, Temperature RT–200°C controllable), significantly reducing interface impedance.
(3) Supports thin-film coating (≤20μm) and damage-free transfer lamination for sulfide/oxide/polymer electrolytes.
● Mass Production-Ready Data Closed-Loop System
(1) Embeds SSB-dedicated MES, monitoring key parameters in real-time: electrolyte film thickness uniformity (CV≤3%), interface contact pressure, hot press temperature profile, interface impedance evolution, etc.
(2) Combines in-situ impedance analysis and CT scan data to build interface contact-electrical performance correlation models, defining mass production process windows.
● Zero-Electrolyte-Filling High-Reliability Encapsulation
(1) Fully automatic multi-chamber pressurized encapsulation machine (Vacuum ≤10⁻³Pa, Pressure accuracy ±0.5MPa), addressing the air-tightness challenge of SSBs.
(2) Compatible with aluminum laminate film/metal case encapsulation, meeting high energy density and extreme safety requirements.
● Seamless Mass Production Design
(1) Core equipment (Dry film forming machine, Hot press, Pressurized encapsulator) shares the same underlying technology platform as mass production lines.
(2) Process parameters (Hot press pressure/temperature profiles, stacking accuracy, interface activation regimen) can be directly extrapolated to GWh-scale production lines.
From solid-state technology blueprint to stable sample delivery, TOB empowers the entire journey.

Core enablers of technological implementation
Actionable insights from planning to execution
● No Electrolyte Filling Process: Eliminates electrolyte filling/soaking equipment; adds hot press integration and interface activation modules.
● Upgraded Environmental Control: Sulfide lines require full-chain H₂O/O₂ ≤0.1ppm (increases cost share by ~30%).
● Increased Encapsulation Pressure: Encapsulation pressure increases from ~0.5MPa for liquid electrolytes to 5–50MPa.
● Process Side: Uses multi-stage gradient hot pressing (Programmable temperature/pressure profiles) + in-situ curing layers (Li-alloy interface layer deposition equipment).
● Equipment Side: Integrates real-time impedance monitoring modules, automatically feedback-adjusting hot press parameters.
● Material Side: Provides pre-lithiated anode / surface-modified electrolyte supporting solutions.
● Environment: Requires independent dust control chamber (ISO Class 5 cleanliness).
● Equipment: Equipped with powder electrostatic elimination system, precision feeder (Accuracy ±0.1g).
● Safety: Full-process inert atmosphere explosion-proof design (PTFE powder ignition point ≤450°C).
