TOBGROUP Solid-State Battery Lab Line: Bridging R&D from Atomic-Level Design to Cell-Level Validation
● Modular Process Platforms
(1) Electrolyte Module: Powder ball milling/spray drying (particle size D50 ≤1μm) → Thin film sputtering/tape casting (thickness 1-100μm) → Hot pressing densification (relative density ≥95%).
(2) Electrode Module: Dry-process electrode continuous film formation (solvent-free) → Co-sintering with solid electrolyte → Interface activation treatment (laser/plasma).
(3) Integration Module: Multi-layer laminator (temperature/pressure gradient control) → In-situ curing device (UV/thermal initiation).
● Multi-Dimensional Characterization System
(1) Structural Analysis: In-situ XRD (crystal phase evolution during charge/discharge).
(2) Interface Diagnosis: EIS-Mapping (spatial resolution 10μm).
(3) Mechanical Properties: Nanoindentation (modulus measurement accuracy 0.1GPa).
(4) Thermal Management: Synchrotron radiation CT (real-time dendrite growth monitoring).
● Intelligent R&D Management
(1) Digital Twin System: Automatic correlation of process parameters with performance data (e.g., pressure-interface impedance-cycle life models).
(2) Material Genome Database: Accumulated database of 3000+ electrolyte formulations, supports AI-assisted material screening.
