Batteries with nanotubes


Description under the cut
In short, we take paper (any less dense for example of copying equipment will do) and nano-ink (water suspension of nanotubes). We put the last on paper and we dry up in the thermostat, we receive the high-conducive paper applied to modernization of ordinary batteries or creation new.

This video is for those who are interested in how nanotubes are made.


Wikipedia excerpt:
The synthesis process is carried out in a chamber filled with helium under a pressure of about 500 Torr. During plasma combustion, intense thermal evaporation of the anode occurs, and a precipitate is formed on the end surface of the cathode, in which carbon nanotubes are formed. The greatest number of nanotubes is formed when the plasma current is minimal and its density is about 100 A / cm2. In experimental installations, the voltage between the electrodes is usually about 15-25 V, the discharge current is several tens of amperes, the distance between the ends of the graphite electrodes is 1-2 mm. During the synthesis, about 90% of the mass of the anode is deposited on the cathode.

In general, the prospects are drawn brightly, the question "when will they be introduced into mass production?"

UPD The paper is immersed in a solution containing lithium and electrolytes to provide a chemical reaction that generates an electrical current in the batteries. Paper only “collects” energy.
