ECD-4-nano
ECD-4-nano is a high-resolution electrochemical dilatometer with a capacitive parallel plate sensor offering sub-5 nm resolution, ideal for monitoring electrode or full cell stack thickness changes during electrochemical cycles.
1. Redesigned Test Cell
- Corrosion-resistant cell bottom for use with a wide range of electrolytes
- New One-Seal concept significantly improves tightness compared to ECD-3
- Enables stable long-term operation
2. Integrated into PAT System
- Can be inserted directly into PAT-Tester-x or docking station such as PAT-Clamp-1
- Space-saving and fast setup
- Integrated PAT-Button ensures automatic recognition in EL-Software
3. Use Cases
- Expansion of individual electrode (3-electrode setup with ring-shaped reference electrode)
- Expansion of full cell stack (2-electrode setup)
- For aprotic electrolytes
4. Additional Key Features
- Capacitive displacement sensor (range 250 μm, resolution ≤ 5 nm) arrangements
- Additional gas pressure sensor (0–3 bar) and temperature sensor (-20 to 80°C)
- Cableless connection via PAT socket with electronic cell tag (PAT-Button)
