Single-channel potentiostat/galvanostat with EIS Model CS360 consists of a DDS arbitrary function generator, a potentiostat /galvanostat and an FRA.  With the help of built-in dual 24-bit Delta-sigma AD converters, it achieves excellent stability and high potential (1mV) and current(1pA) resolutions.With EIS frequency up to be 8MHz, CS360 has been an ideal tool for the study of solid-state electrolyte. 

Applications

- Energy materials (Solid-state battery, Li-ion battery, solar cell, fuel cell, supercapacitors, etc)

 - Electrocatalysis (HER, OER, ORR, CO2RR, NRR, water splitting)

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

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

With virtues of high energy density, fast charging &discharging, and long lifespan, solid-state batteries are  widely used in electric vehicles, wearable devices and so on. Featured by leak-proofness, flame retardancy and inhibition of dendrite growth, solid-state electrolytes enhance the safety of batteries. ElS is an important technique to study the performance of solid-state batteries. It can provide information about charge transfer, electrochemical reactions, etc by measuring EIS in various frequency regions, further providing important theoretical basis and technical support for the development of high-performance fully solid-state batteries.

The EIS frequency can be up to 8MHz for CS360 electrochemical workstation, which can meet the need of high-frequency EIS test on solid electrolytes. Study of solid electrolytes especially focus on impedance behavior in high-frequency region. It helps us to quantify the electronic &ionic conductivity, find microstructural problems of the material (such as grain boundary effects), and thus provide guidance on material optimization, and battery performance improvement.
