I have recently come up with an idea. I was just wondering if this is hypothetically possible in any way. Is it possible to combine aluminum-ion battery technology with supercapacitor technology? My idea was to create a capacitor with tetrachloroaluminate-intercalated graphite as one electrode and a piece of one-side anodized aluminum as the other electrode. The dielectric separating the electrodes would be the aluminum oxide layer on the aluminum. When the layers are stacked, instead of separating them with just paper, I was thinking of using a paper soaked in a solution of tetrachloroaluminate ions(the electrolyte). The electrolyte-soaked paper would allow the tetrachloroaluminate ions to diffuse through and transfer electrons to the aluminum (which is not anodized on this side).

Would this be a valid supercapacitor and why?

Note: I have no electrical engineering knowledge. I just want to know if this may/may not work when I try it. It is for a small project.

Thanks for your help in advance!

    \$\begingroup\$ i do not know if it would work .... upvote for the idea .... btw: isn't a cow topologically identical to a klein bottle ... lol \$\endgroup\$ – jsotola Feb 5 at 4:22

    \$\begingroup\$ yes, i am referring to your profile picture .... it is pretty funny .... now thinking about it, maybe a cow is topologically identical to a taurus (torus) .... lol \$\endgroup\$ – jsotola Feb 5 at 4:25
  • \$\begingroup\$ So by anodizing one side of the aluminum electrode, you're effectively cutting your battery's current capacity in half in exchange for what, exactly? The overall capacitance between the electrodes won't be changed by this. \$\endgroup\$ – Dave Tweed Feb 5 at 13:20
