Need suggestions for biomass-derived activated carbon for supercapacitors application. when i run the instrument may sample is peeling off into electrolyte solution (KOH)..
Dear Andem Sandeep
If the sample is peeling off from the Ni-foam substrate during electrochemical studies in KOH electrolyte solution, there are a few things you can try to prevent this from happening:
For biomass-derived activated carbon for supercapacitor applications, it is important to optimize the preparation method to achieve good pore structure and surface area. You can try using a variety of biomass precursors and activation methods such as physical activation, chemical activation, or a combination of both to achieve the desired properties. Additionally, it is important to optimize the electrode fabrication and testing conditions to achieve the desired electrochemical performance.
It depends on binder material, increase the content of PDVF or PTFE binder material and mix properly in mortar for more time. If you use more than 1.2 V voltage window then carbon material peel off.
