Application
●Study of Energy materials (Li-ion battery, solar cell, fuel cell, supercapacitors), advanced functional materials

● Bioelectrochemistry, sensors, electrosynthesis, electrodeposition (electroplating), anodic oxidation, electrolysis

Corrosion Electrochemistry

CS potentiostats/galvanostats support a variety of electrochemical techniques for corrosion, such as OCP recorder, potentiodynamic, EIS, cyclic polarization (CPP), LPR, hydrogen diffusion test, zero resistance ammeter (ZRA), electrochemical noise (ECN), etc.

Due to their high input impedance(10¹³Ω), they are especially suitable for EIS measurement of high-impedance systems like coating, concrete, and pure water.

Salt spray aging test of high impedance coating

Energy & Battery testing
With versatile functions like linear sweep voltammetry (LSV), cyclic voltammetry (CV), galvanostatic charge/discharge (GCD), EIS (including potentiostatic and galvanostatic modes) with precise IR compensation, CS potentiostats are widely used in supercapacitor, Li-ion batteries, Li-S batteries, fuel cell, solar cell, solid-state batteries, flow batteries, and metal-air batteries, etc.

CV curve of PPy supercapacitor in 0.5 mol/L H2SO4 solution

Analytical Electrochemistry

CS potentiostats include comprehensive voltammetric methods such as NPV, DPV, DNPV, SWV, and ACV, which make them ideal for quantitative analysis of trace elements via the intrinsic Voltammetry stripping techniques.

Stripping voltametric curves in solution of different Pb2+, Cd 2+,Zn2+ concentration

Electrocatalysis

Based on CV and LSV techniques, CS potentiostats can carry out long-term tests for ORR, OER, HER, and CO₂ reduction, which is crucial for evaluating catalyst stability. In addition, the CS2350M bi-potentiostat and multichannel potentiostat specialize in Faradaic efficiency synchronous measurement.

CS potentiostats can measure the half-wave potential (ORR) and overpotential (HER, OER) of catalysts and calculate the power density and energy density of Redox peaks.

LSV curve of catalysts in alkaline solution

Electrochemical Sensor

Thanks to the high current sensitivity(100fA) and voltage resolution(1 mV), the CS potentiostat can be used for the R&D of biosensors and electrochemical sensors.

Technical Advantages
Switchable floating and earthing mode

All CS potentiostats/galvanostats can switch between the floating and earthing modes, and this strategy is beneficial for studying electrochemical systems in which the working electrodes are intrinsically ground, such as autoclaves, in-site concrete structures and multi-working electrodes requiring isolation, etc.

High-bandwidth EIS

With the help of built-in digital FRA and arbitrary signal generator, as well as the high input impedance (10¹³W), the CS potentiostat is particularly suitable for EIS measurements of high-impedance systems (such as coating, membrane, concrete, etc.)

Based on the DC bias compensation technique, CS potentiostats can conduct EIS tests under different charge/discharge states of batteries, making them suitable for ultra-low resistance systems, such as power batteries, fuel cells, water-splitting equipment, etc.

Multi electrode configurations

CS potentiostats support 2-, 3-, or 4-electrode configurations and can measure the galvanic current via built-in zero resistance ammeter circuits.

Independent multiple channels

For CS 310X multi-channel potentiostat, each channel is completely independent. It can be used for the electrochemistry measurements of multiple cells or multiple working electrodes in a cell.

CS2350M Bipotentiostat/multi-channel potentiostat can be used for the RRDE test, dual-cell hydrogen diffusion test.

User-defined sequence test

CS Studio 6.0 for Windows software supports user-defined sequence tests (“combination test”), which can facilitate automatic testing according to user-defined experiment sequences.

Sequence Test: corrosion tests

Sequence Test: Pseudocapacitor tests

Power booster

Through CS2020B/CS2040B/CS2100B booster, the CS potentiostats can extend their output current up to ±20A/40A/100A, meeting the growing requirements in fuel cells, power batteries, electroplating etc

The compliance voltage of single-channel potentiostat can be customized(±30V),suitable for carbon/nitrogen electrochemical reduction.

With a multiplexer, the CS single-channel potentiostats can be extended to 16~32 channels for high throughput testing.

CS potentiostats can work with a CST520 arrayed electrode mapper to study the non-uniform corrosion of metal samples under deposits, coatings and anti-rust oils.

Software development kit(SDK)

All CS potentiostats run under the control of CS Studio 6.0 for Windows (CSS 6.0). The CSS6.0 supports third-party languages, such as LabVIEW, C, C++, C#, VC, Python and others. Some API general interfaces and development examples can be supplied with the CS potentiostats. Through the SDK, customers can implement user-defined test methods.

Real-time data storage

CSS 6.0 saves experimental data timely, even if the experiment is accidentally interrupted by a power failure or computer shutdown. CSS 6.0 supports several data formats compatible with Originpro and Microsoft Excel.

Versatile data analysis

CSS 6.0 provides robust functions, including various electrochemical measurements and data analysis. It can complete Tafel plot fitting, CV derivation, integration and peak height analysis, EIS equivalent circuit fitting, etc.

3, 4 parameter polarization curve fitting.

Software Features

Cyclic voltammetry:
CS studio software provides users a versatile smoothing/differential/ integration kit, which can complete the calculation of peak height, peak area and peak potential of CV curves. In CV technique, during the data analysis, there is function of selecting exact cycle(s) to show. You can choose to see a cycle or some cycles as you want. You can also export data or vector graph of an exact cycle or several cycles.

Tafel plot and corrosion rate:

CS studio also provides powerful non-linear fitting on Butler-Volmer equation of polarization curve. It can calculate Tafel slope, corrosion current density, limitation current, polarization resistance, corrosion rate. It can also calculate the power spectrum density, noise resistance and noise spectrum resistance based on the electrochemical noise measurements.

Battery Test and analysis:
charge & discharge efficiency, capacity, specific capacitance, charge & discharge energy.

EIS analysis: Bode, Nyquist, Mott-Schottky plot
During EIS data analysis, there is built-in fitting function to draw the custom equivalent circuit.
