Fogli flessibili di grafite per batterie

In questo video viene descritto un metodo per la realizzazione di fogli conduttivi in grafite, questi fogli possono essere usati per molte applicazioni, tra cui elettrodi per batterie.
Alla fine i particolari costruttivi dell' elettrodo al carbonio usato nella batteria; alluminio, ipoclorito di sodio.

If this material for current collector, this have too high resistance

This is correct, but I'm working on lowering the electrical resistance of these sheets

@@claudiohomelab8181 no, you must learn what flexible graphite foil is, it's have resistance near metal but inert to chemical reaction, it's the true current collector, what you try to make is cathode material not current collector

It's interesting what you say.
Can you tell me where to find information about these graphite foils to be used directly as a current collector?
The electrodes that I prepare with these foils have a stainless steel mesh manifold, so in effect they are cathode material

@@teknosql4740 Graphirte foils or grafoils are very fragile and only practical for lab experiments. What Claudio is doing is quite practical and he can easily go to 0 Ohm and it can be used as a cathode material and or a current collector!
