KARPEN PILE

[profitis]

I think we should seal gadget when we get the cathode sorted for max power what do you think pomodoro?

I just had an idea for a non-nanotech battery.
Sorry, I don't immediately visualize these ion systems / leakage systems.

Use semiconductor silicon slabs cut from a boule as the base metal for a battery.
Could use either acidic or basic electrolyte.

a) deposit anode and cathode material as slightly overlaping stripes all the way across
the silicon slabs. This will form the series cell voltage area.

b) manufacturer can form a silicon dioxide layer = glass insulator and electrolyte rejection.
     (Semiconductor industry uses Fluoric acid to etch silicon dioxide off.)

c) manufacturer could also "radiate-inject" dopant metal ions into the silicon slab to turn areas
into N and P diode regions if you need to bias the base metal silicon on or off, if that will protect
it from corrossion. (You could artificially bias it with a voltage doubler if more is required.)

d) attach to a radial support structure as shown in the original Karpens Cell.

e) shove the above structure into a glass tube add electrolyte and seal.

....One may be able to do a glass-mat battery with above, glass proof of product
them move to available poly- plastic containers. If one needs to do depolarization
electronics for cell one could use use modified "lithium battery" like top compartments.

Interested in plating cost per square area, power per 1/2 square area.
Cautions about 2Lot thermal energy generators apply.

Thank you mscoffman.


Here is an update, this morning I found the silver electrode behaving sluggishly.  It was not recovering to the 800mv mark in the 60 seconds any more, but more around the 600 mark, and the discharge was reading a lot lower, about 400uA.  The electrolyte had floating bits and was darker.  Even bubbling hydrogen had little effect.

The Pt/Pd still behaved well so it is the silver that is playing up.

I cleaned up the cell with fresh KOH, cathodized the Pd/Pt and anodized/cathodized the silver but still results are not the best. It looks like the silver needs to be cleaned up in nitric acid for it to work well again...  While we ponder on this problem I set up the cell with the graphite electrode instead, anodized and cathodized as before. Now it works well, check out the constant 400uA and 40mV across the 100 ohm +15 of the meter, no need to pulse discharge this one!.  Whats going on, surely the graphite must have a metal oxide contamination on the surface, but then again, the hydrogen gas in the solution should reduce it ?  Check the link..

The graphite behavior is interesting.  Is it possible to leave it running for an extended period of time to see if it is decaying albeit slowly?

The graphite anomaly has been solved.  I wonder if anyone here can solve it too, it has to do with the apparatus I set up not being perfect. its actually a big problem when studying this hydrogen powered  karpen, especially because the hydrogen on the Pd/Pt will reduce anything it can over at the cathode electrode, and it means I have to run the silver again.
