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...

This study presents a thermal model, derived from first principles, for electric double layer capacitors (EDLCs) with multiple ion species and/or asymmetric electrolytes. It accounts for both irreversible and reversible heat generation rates resulting from the transient electrodiffusion of ions within the electrolyte. Detailed numerical simulations of EDLCs with planar electrodes and binary and...

In the commentary to our paper [Electrochimica Acta 63 (2012) 55], Roling and Drüschler raised a very important issue regarding the measurements and comparison of the differential and integral capacitances retrieved using electrochemical impedance spectroscopy (EIS). They clearly explained that EIS measures differential capacitance rather than integral capacitance. The present letter aims to co...
