Is there any specific standard for current densities while taking charge/discharge data? I mean at what current densities the data should be taken for publications?
Well, there is no standard rule that you must start from a specific current density. But you can start with a current density of 1 A g-1. Most of the papers reported till date start with this current density.
There are many papers in which people reported GCD at lower current densities or higher than 1 A g-1 also. So, you can measure GCD at various current densities and optimize a specific range based on your results.
(In my case, GCD measured at lower current densities i.e.,
Thank you very much Debika Gogoi.
So, I should start from lower current density ( say 0.5 or 1 A/g) and then I need to go towards higher current density (upto 20 or 40 A/g) with some step length.
Dear Adwaita Kundu,
You can start at a lower current density of (0.5 A/g or 1 A/g) depending upon your sample, and then move toward higher current density (20 A/g). I am attaching some papers below for reference. Thanks
1. Constructing Conjugated Microporous Polymers Containing the Pyrene-4, 5, 9, 10-Tetraone Unit for Energy Storage.
2. An Ultrastable Porous Polyhedral Oligomeric Silsesquioxane/Tetraphenylthiophene Hybrid as a High-Performance Electrode for Supercapacitors.
3. Constructing conjugated microporous polymers containing triphenylamine moieties for high-performance capacitive energy storage.
4. Ultrastable covalent triazine organic framework based on anthracene moiety as platform for high-performance carbon dioxide adsorption and supercapacitors.
Usually for comparison, researchers reports 1 A/g. If you can start from 0.25 or 0.5 or 1 A/g, then no issue. Based on your your electrode activity, you can carry out.
Regarding much high current density
If in your electrochemical workstation updated with current booster, then you can carry out in at higher current above 20 A.
