Turquoise Battery Project - creating superior, economical batteries
Craig Carmichael
In 2008 I decided to try creating a superior but economical battery chemistry. The art of battery making didn’t seem to be very well explored. Especially, salty electrolyte cells had had no real development since the standard dry cell in the 1880s.
What’s in a battery? [show & explain parts]
- Case
- Electrode briquettes
- Current collectors & terminals
- Electrolyte
But all common metals including nickel corrode in salt anodes. Carbon rods and graphite sheets gave poor results. So I invented ‘grafpoxy’, a conductive mixture of epoxy and graphite to allow coated metal electrode screens and connections. That opens up the whole salty battery field.
Chemicals and reactions also appeared to be almost unexplored for salty electrolyte. I found a number of good substances and reactions.
Positive Electrodes
- Nickel hydroxides
- Vanadium oxides
- Manganese oxides
- Rare earth perchlorate-chloride
Negative electrodes
- Nickel
- Zinc
- Manganese — the new highest energy electrode
I’ll put instructions for making these batteries into a book on the web.
