Phone batteries have drastically improved over the years, however, scientists at the University of Central Florida have reached the next evolution of battery chargers. They have developed a very thin, flexible supercapacitor which offers high energy density, and works well for electronic devices becoming more powerful but reducing in size.
“We developed a simple chemical synthesis approach so we can very nicely integrate the existing materials with the two-dimensional materials,” said lead researcher, Yeonwoong Jung. It means this tiny two-dimensional supercapacitor is able to hold the same amount of energy as a lithium-ion battery.
The material used is called transition-metal dichalcogenides or TMD that transfers electrons at super-speed which means lightning-fast charging, in comparison to a regular battery. It also does not degrade over time and lasts over 30,000 charge cycles, comparatively to lithium-ion iPhone battery that starts to wear after 300-500 cycles and won’t last after 1500 charging cycles.
Researcher Nitin Choudhary explains, “If they were to replace the batteries with these supercapacitors, you could charge your mobile phone in a few seconds and you wouldn’t need to charge it again for over a week.”
The technology is not yet ready for commercial use, however, Jung is currently working to have it patented. Once it becomes available, it will take our electronics, from smartphones to wearables, even electronic vehicles, a step further.
The study is published in the journal ACS Nano.
