Description

Electrochemical testing lab aims to test the electrochemical response of any electrochemical energy systems (i.e. battery materials, batteries, super-capacitors, customized cells, etc.). Typical electrochemical protocol would be galvanostatic cycling, cyclic voltammetry, electrochemical impedance spectroscopy, C-rates and more in-depth analysis such as GITT, PITT can also be realized. The electrochemical testing could be performed at various temperature (from -70ºC up to 180ºC) and using various currents (from microamps to several amps).

Testing equipment available at CIC energiGUNE is useful for a wide range of applications:

• Materials
• Half-cell battery
• Full cell (Li-ion, Na-ion, all solid state, etc.) battery
• Redox flow battery
• Battery pack
• Supercapacitor
• Li-ion and Na-ion capacitors
• Metal air cells
• Microbatteries
