Abstract Atomic hydrogen can be the result of different processes like electroplating, chemical and electrochemical pickling treatments, in welding or by cathodic corrosive fluids. Moreover, adsorption atomic affect materials contact with high pressure gaseous hydrogen. Once entered material, interacts metal structure may produce a “damage” various forms, such as Hydrogen Induced Cracking (HIC)...

Electrochemical Impedance Spectroscopy(EIS) is a standard technique for analyzing batteries in detail. It immensely powerful as it can yield separate information about various components and interfaces inside while the battery intact operational. One drawback of EIS measurement relatively large time requires.One potential way to improve this issue use multisine, akin Fourier Transform technique...
