Battery charging less than 30 seconds
Extremely surprised, the news is already a bit "outdated", although this information has been known since Saturday, but has not affected Habr in any way. Despite the rather yellow headline, the news really sounds that way.
Indian-born Californian, Isha Hare (Eesha Khare) invented an innovative “supercapacitor” that can charge in less than 30 seconds.
Details have not been disclosed, but everything is clear here, this kind of technology will have to be very popular.
The 18-year-old US schoolgirl received the award as the best invention of the Intel Foundation Young Scientist Awards .
The invention, according to experts, will contribute to the creation of a new method of charging mobile devices, with ultra-fast charging of batteries for tablet computers, phones and smartphones. Designed "supercapacitor" can be integrated into batteries that can be charged in 20-30 seconds. In addition, the next huge plus is known, namely, the number of recharge cycles will be approximately 10 times more than the current (10,000 times vs. 1,000).
The dimensions of the device do not exceed 3 cm.
')
When asked by journalists what exactly was the source of inspiration for this idea, the inventor replied: "The battery of my mobile phone is always discharged."
At the moment, the invented test sample provides only a small LED. And although the award for the invention of this level is very modest ($ 50,000), Google Corporation became interested in Isha Hare and offered a place to study at Harvard University.

To improve the supercapacitor energy density, it is designed, it is synthesized, it is characterized by the core core and the polyaniline shell. H-TiO2 acts as a double layer of electrostatic core. Good conductivity of H-TiO2 is combined with the polyaniline results in significantly higher capacitance and cycle energy. It was a practical application.
