The battery has always been huge and bulky, taking up a lot of space in your phone or tablet. What if they could be removed and replaced with a new type of wire? This is the goal of the nanotechnology research team at Central University in Florida. They envisioned the development of a new wire that could store energy in the body instead of a battery.
Professor Jayan Thomas and his students have developed a technique in which they use a sheath made of alloy nanowhiskers to cover the wires, and this sheath will become one of the electrodes constituting the supercapacitor. The researchers then added a second layer of nanowhisker tube sleeve as the second electrode, and added a thin plastic layer between the two layers of nanowhisker sleeves to form a complete capacitor. The inner copper core of the wire still retains the ability to conduct current, but now it also increases the ability to store energy.
Dr. Thomas said that the reduction in volume and weight may be beneficial to the development of electric vehicles, especially space vehicles. And the reduced version of the design can be used for smartphones and other personal gadgets. So far, this research team has been working on this kind of wire research, but they claim that this technology may also be applied to fiber cloth, so that you can make energy-producing clothing.
Dr. Thomas added: "I just hope that all these supercapacitors will not lose their ability to retain charge as they age, because it will be very bad if they need to be replaced after hundreds of charging cycles. Because they may It will not be as easy as replacing a traditional battery, and it may be very inconvenient. "
