Electrochemical Impedance Spectroscopy (EIS)

Researchers, do you face problems? like,

• Energy devices deliver lower power output because high charge-transfer resistance impedes efficient electron flow.

• Poor compatibility between the electrode and electrolyte leads to unstable performance and premature device failure.

• Batteries and electrocatalysts suffer from slow ion diffusion, limiting efficiency and rate capability.

• Internal resistance increases over time, causing overheating, energy loss, and reduced operational lifespan.

• Protective coatings fail unexpectedly due to barrier breakdown, exposing materials to aggressive environments.

• Corrosion remains undetected in its early stages, resulting in costly structural damage and increased maintenance costs.

• Interfacial instability between materials causes gradual performance degradation in energy storage and conversion systems.

Electrochemical Impedance Spectroscopy (EIS) helps you diagnose your problems and find their optimal solutions.

It is a frequency-domain technique in which a small-amplitude AC perturbation is applied over a defined frequency range to analyze interfacial charge transfer, mass transport, and capacitive behaviour in electrochemical systems.
