Testing cell samples

Ongoing research is dedicated to identifying new material combinations for battery cells. Cell samples are set up and characterized to achieve this. In addition to the galvanostatic test methods, cyclovoltammetry is frequently used as an analytical method for identifying the electrode processes. For detailed tests, the devices under test (DUT) have an additional reference electrode.

Scienlab has developed special test systems for this task:

  • Voltage range: -2...8 V
  • Output current: up to ±5 A
  • Measuring ranges: ±150 μA, ±5 mA, ±150 mA, ±5 A, automatic range switchover
  • Manual parallel connection: 2 channels to increase the current to max. 10 A
  • Control modes: current, voltage, power
  • Optional Electrochemical Impedance Spectroscopy (EIS)


  • Characterization, selection and optimization of cell chemistry and material in R&D, production and for quality assurance purposes
  • Simultaneous characterization of up to several hundred cell specimens e.g. round cells (e.g. 18650 housing), button cells, laboratory cells with reference electrode
  • Identification of the electrode processes: galvanostatic and potentiostatic test methods, cyclovoltammetry, etc.
  • Determination of capacity, energy, power, voltage, internal resistance, efficiency


  • Connection for one reference electrode and for one temperature sensor in each test channel
  • Control based on all 3 voltages: anode/cathode, cathode/reference electrode, anode/reference electrode
  • Also suitable for high-voltage materials up to 8 V
  • Measuring accuracy of up to 0.03 μA
  • Intuitive ESD testing and control software for reproducible and reliable measurement results
  • Integrated evaluation of the cyclovoltammetry and the Incremental Capacity Analysis (ICA) in ESD
