DIY Rechargeable Cell Chemistry? Answered

Hi i was wondering if there was any electrically reversible battery chemistries that can be made from around the house materials like copper wire, iron nails, galvanized nails, graphite rods, aluminum foil, and other items like those.


This wouldn't be a rechargable battery, but you could make a salt water battery, and change the salt when ever the battery "dies"

I've been looking around for the same thing. No luck thusfar though.

I'm not really sure exactly what you want, but you could try making a leyden jar out of a bottle and some foil, i think.
