Despite phone batteries drastically improving over the years, you still have to religiously plug in before going to bed or else risk the 9% panic speed walk to the tube.
But there could be a solution on the way. Scientists at the University of Central Florida have developed a thin, flexible supercapacitor which offers high energy battery capabilities. This nanotechnology solves the issue of our electronic devices becoming more powerful but reducing in size.
According to lead researcher Yeonwoong Jung, "We developed a simple chemical synthesis approach so we can very nicely integrate the existing materials with the two-dimensional materials." This means the two dimensional supercapacitor is able to hold the same energy as a lithium-ion battery without increasing in size.
Better yet, the material used (called transition-metal dichalcogenides or TMD) transfers electrons more quickly than a regular battery which means lightning-fast charging. They also don't degrade over time, lasting over 30,000 charge cycles - comparatively your lithium-ion iPhone battery starts to wear after 300-500 cycles and won't last after 1,500 charging cycles.
"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," researcher Nitin Choudhary explained.
The technology is currently being patented so will be while before it is upgrading your smartphone experience, but just imagine Glastonbury without battery-induced anxiety.
