Application

-Energy materials (Li-ion battery, solar cell, fuel cell, supercapacitors, electrocatalysis; 

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. 

-Reactive mechanisms of electrosynthesis, electrodeposition (electroplating), anodic oxidation, electrolysis; 

-Metallic corrosion; corrosion inhibitor, coating and cathodic protection efficiency;

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.

-Electrocatalysis (HER, OER, ORR, CO2RR, NRR).

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 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.

Simultaneous Measurements
The customer can choose a same electrochemical technique in every channel. For example, among 8 channels, you can choose to run 4 channels to all do EIS measurement. Set the parameters just one time, then EIS measurement in each channel will be conducted at the same time.(Here is an example of using the 4 channels. You can run the 8 experiments at the same time on one window)
 

In each channel, you can also conduct different experiments. As is shown in the below picture, EIS, galvanostatic charge and discharge, CV, and polarization curve tests are conducted at the same time.(Here is an example of using the 4 channels. You can run the 8 experiments at the same time on one window)
 

Thanks to the expandable slot design, Customers can open the chassis and install more potentiostat board to increase the number of channels. 

Standard potentiostat/galvanostat boards

In one chassis, there are 8 slots inside. 

For 4-channel, four standard Pstat/Gstat boards are installed and there are 4 empty slots for future extension of channels. 

For 8-channel potentiostat, eight standard Pstat/Gstat boards are installed in the 8 slots.

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 (10¹³ W), 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.

Multiple 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.

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.

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.

Overcurrent overpotential protection

The software will give an “overload current” or “overload potential” warning if the current or potential is exceeding the maximum current/ potential output of the instrument. The test will stop automatically.

Real-time data saving

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.

Multi-user capability

Channels of the CS310X can be allocated to multiple users on various computer.
