When applying currents ranging from 1 to 8 mA to charge my electrode, it fails to reach full charge, and instead, after some time during the charge cycle, it exhibits a straight line pattern on the graph. What factors might be causing this behavior?
Ashwani Maurya The straight-line pattern observed during low-current electrode charging can be attributed to diffusion-limited charging, double layer capacitance, surface kinetics, adsorption, pore size, electrode material, cell design, and potential instrumental artifacts.
thanks Alvena Shahid mam so, is this the reason that it fails to reach full charge ?
how can we improve the electrode so that it can be charged even at lower current (1 to 8 mA). ??
Ashwani Maurya While material modification and an understanding of electron transport mechanisms are necessary, nanostructured coatings, optimized electrolytes, and faradaic mediators can be used to improve electrode performance in galvanostatic charge-discharge studies.
