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 of CS360 potentiostat
- 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
potentiostat/galvanostat/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.
