charge your mobile in 20 seconds
Currently cells phones typically take several hours to charge.Electric cars are held back even further by the constant need to charge them for many hours after each day, not to mention the fact that there is no easy way to recharge them at gas stations due to the time it takes. However all of this could change if Eesha Khare – an 18-year-old student from California will have her way.
Khare made a breakthrough by creating a small supercapacitor that can fit inside a standard cell phone battery and enable ultra-fast electricity transfer and storage, delivering a full charge in as little as 20-30 seconds.
Another interesting ability of the supercapacitor developed by Khare is its endurance. while conventional batteries can charge and discharge about 1000 times before they lose a substantial amount of power, Khare’s supercapacitor can last for 10,000 charge-recharge cycles.
Khare was apparently frustrated with the short life of her cellphone battery and wanted to do something to tackle this problem so she turned to science and under the supervision of Dr. Yat Li at the Department of Chemistry and Biochemistry at the University of California, Santa Cruz she created a solid-state device with a hydrogenated TiO2 (H-TiO2) core that was able to power a LED light and during testing only lost 32.5% over 10,000 charging cycles.
