Product Advantages
Electrode Tortuosity Analyzer
3D Microstructure Imaging:
Sub-micron resolution CT scanning reveals tortuosity pathways in 3D.
Automated tortuosity factor calculation (τ < 1.2 for ideal structures).
Non-Destructive Analysis:
X-ray-free optical tomography preserves sample integrity.
60-second full-volume scan for rapid R&D iteration.
Multi-Material Compatibility:
Tests dry electrodes, slurry-coated foils, and solid-state composites.
Separator Ionic Conductivity Tester
Ultra-Wide Conductivity Range:
Measures 0.01 mS/cm to 20 mS/cm for ceramic/polymer hybrids.
AC impedance spectroscopy up to 10 MHz.
Automated Liquid Handling:
Programmable electrolyte injection (0.1–100 μL precision).
Self-sealing sample chamber prevents evaporation.
Temperature-Controlled Testing:
-20°C to 80°C Peltier stage with ±0.1°C stability.
Product Features
Electrode Tortuosity Analyzer
Laser-Guided Alignment: Ensures precise sample positioning (±2 μm accuracy).
AI-Powered Analysis: Machine learning identifies critical pathways in 3D datasets.
