Single Channel Electrochemical Workstation Potentiostat Galvanostat For Battery Testing Research

CS electrochemical workstation (potentiostat / galvanostat) contains a fast digital function generator, high-speed data acquisition circuitry, a potentiostat and a galvanostat. With high performance in stability and accuracy with advanced hardware and well-functioned software, it is a comprehensive research platform for corrosion, batteries, electrochemical analysis, sensor, life science and environmental chemistry etc.

Applications
(1) Reaction mechanism of Electrosynthesis, electrodeposition (electroplating), anodic oxidation, etc.
(2) Electrochemical analysis and sensor;
(3) New energy materials (Li-ion battery, solar cell, fuel cell, supercapacitors), advanced functional materials, photoelectronic materials;
(4)Corrosion study of metals in water, concrete and soil etc;
(5) Fast evaluation of corrosion inhibitor, water stabilizer, coating and cathodic protection efficiency.

Technical advantages

1. Impedance (EIS)
CS potentiostat applies correlation integral algorithm and dual-channel over-sampling technique, and has strong anti-interference ability. It is suitable for EIS measurements of high-impedance system (>109Ω, such as coating, concrete etc.). It can also be used to obtain Mott-Schottky curve and differential capacitance curve. During test, the software can display real-time open circuit potential(OCP) without entering.

2. Polarization curve

Polarization curve / Tafel plot can be obtained. The user can set the anodic reversal current (passivation film breakdown current) of the cyclic polarization curve to determine material’s pitting potential and protection potential and evaluate the its susceptibility to intergranular corrosion. The software employs non-linear fitting to analyze polarization curve, and can make fast evaluation of material’s anti-corrosion ability and inhibitors.

3. Voltammetry

It can do the following experiments: Linear Sweep Voltammetry(LSV), Cyclic Voltammetry(CV), Staircase Cyclic Voltammetry(SCV), Square wave voltammetry(SWV), Differential Pulse Voltammetry(DPV), Normal Pulse Voltammetry(NPV), AC voltammetry(ACV), Stripping voltammetry etc. It integrates calculation of peak area, peak current and standard curve analysis.

4. Electrochemical Noise
With high-resistance follower and zero-resistance ammeter, it measures the natural potential/current fluctuations in corrosion system. It can be used to study pitting corrosion, galvanic corrosion, crevice corrosion, and stress corrosion cracking etc. Through noise spectrum, we can evaluate the inducement, growth and death of metastable pitting and crack. Based on calculation of noise resistance and pitting index, it can complete localized corrosion monitoring.

5. Full floating measurement

CS workstation uses full-floating working electrode. It can be used for autoclave electrochemical measurements, on-line corrosion monitoring of metallic components under the ground (rebar in concrete, etc.)

6. User-defined methods

CS workstation supports user-defined combination measurements. The user can set cyclic timing measurements of an electrochemical method or several methods.
We are able to provide API functions and development examples, which facilitates some users’ requirements for secondary development and self-defined measurements.
