Product overview

Watch your electrodes breathing

The ECD-3-nano is the dilatometer with a displacement resolution in the nanometer range. The capacitive parallel-plate sensor system of the ECD-3-nano can obtain displacement signals of below 5 nanometers. This high resolution makes it possible to explore new territory of electrochemical dilatometry. For instance, quasi 2-dimensional electrode processes like the SEI formation in lithium-ion batteries or the electrochemically driven growth of passivation layers on metal surfaces might become the subject of future dilatometric studies.

The heart of the ECD-3-nano is an electrochemical cell, which is hermetically tight against ambient atmosphere. The two electrodes inside are separated by a stiff glass frit that is fixed in position. The upper (working) electrode is sealed by means of a thin metal membrane through which any charge-induced height change is transmitted towards the sensor/load unit above.

Improvements of the ECD-3-nano (in comparison to previous versions)

  • Elimination of tubing and external valves reduces the risk of leakage and saves effort.

  • Use of special polymer with minimal water absorption reduces drying effort and accelerates work flow.

  • Use of a smaller glass frit reduces amount of electrolyte required (approx. 1 cm³)

  • Better handling saves time and effort.

Upgrade kits for typical configurations

In the standard configuration, the ECD-3-nano is equipped for aprotic electrochemistry (dilatometer cell, sensor and sensor-controller with dc-voltage output -10 to 10 V) with integrated USB data logger. Materials in media contact are stainless steel and PEEK. The user has to provide all peripheral equipment like temperature chamber and potentiostat.

Various add-ons are available for special testing requirements:

Upgrade Kit Aqueous: replaces stainless steel parts by gold parts and thus makes the ECD-3-nano compatible with aqueous electrochemistry.

ECD-3 Full Cell Kit: Part kit for testing full cells without T-frit.

Part Kit for Testing Single Crystals/Grains: Part kit for using single grains or crystals instead of bound electrode films.
