I’ve launched a crowdfunding campaign to try to support a student in building an iron battery. I’ve got video up that talks about where we’ve been so far this year. We have had some success in building the battery and we’re moving to a better construction method.

We would like to test different cathode salts including a better test of potassium ferricyanide. We would also like to test different solvents such as a deep eutectic solvent and ionic liquid. The big, open question is the separator. We can try some natural gels, some in-house polymers and we can see if we can find a commercial polymer that is cheap and available enough to do the job.

I think it will be a great project for an undergraduate chemist with an interest in renewable energy. If you’d like to check out or share the campaign, the link is here:
