US universities have developed a perfect replacement of lithium batteries!

According to foreign media reports, the science team at the University of Central Florida (UCF) has developed a "super battery" capable of storing more energy.

The traditional Lithium Battery 1500 times after the performance began to have varying degrees of attenuation, and this super capacitor can be used continuously for 30,000 times performance will not be reduced.

"Just swap out the battery in your phone with this supercapacitor, and then recharge your phone for a few seconds, then you will not have to recharge your phone for a week." Nitin Choudhary, one of the researchers, Dr. introduction.

People with smartphones generally encounter the problem that when the battery is used for about 18 months, the time it takes to recharge the phone begins to get shorter and shorter. This shows that the battery capacity to reduce electricity.

Scientists have been studying how to use nano-materials to improve the battery capacity, hoping to develop more powerful super-capacitor to replace the battery we are using at this stage.

Earlier, it has been confirmed that two-dimensional materials have strong electrical storage performance. Although some people tried to add graphite formula to two-dimensional materials in the past, the effect is not satisfactory. Researchers at Florida Central University opted to apply a newly invented two-dimensional material to capacitors.

"It has also been a bottleneck in our industry that most of today's researchers face the challenge of combining 2D materials with current capacitive systems and our team has used a simple and easy chemical synthesis method that works well Put the two together, "said lead researcher Yeonwoong Jung.

The supercapacitors developed by the team consist of millions of wires, each measuring just a few nanometers in length, each wrapped in two-dimensional material. High conductivity can speed up the movement of electrons and transfer speed, so that the battery can be ultra-fast charge and discharge. "For small devices, our materials are far beyond the conventional standards in energy density, power density and stability," said Jung. The future, electric vehicles and other equipment can also use this new capacitor. Because of its excellent pliability and its ability to bend, it can also be combined with wearable devices.

Of course, the Central Florida University team also pointed out that it is still some time before the commercial mass production of the super battery is realized. This product is more of a new inspiration for the battery technology research and development.
