New tech means your mobile phone battery could last one week
IMAGINE if your smartphone battery only needed to be charged once per week, according a science breakthrough this will soon become a reality.
IMAGINE if your smartphone battery only needed to be charged once per week.
According to University of Central Florida postdoctoral associate Nitin Choudhary, a supercapacitor battery prototype is set to make this a reality.
“You could charge your mobile phone in a few seconds and you wouldn’t need to charge it again for over a week,” he told Engadget.
Even after being recharged 30,000 times during tests, the battery prototype is still ultra-fast-charging and promises to last more than 20 times longer than conventional lithium-ion cell products.
This is due to the fact supercapacitors don’t use chemical reactions like traditional batteries; rather they store electricity statically on the surface of “two-dimensional” material sheets.
The team used graphene as the two-dimensional material, although this posed a challenge as researchers had to figure out how to get it to integrate with the other materials used in supercapacitors.
Researcher Yeonwoong “Eric” Jung said a solution was found by wrapping 2D metal materials around highly-conductive 1D nanowires.
“We developed a simple chemical synthesis approach so we can very nicely integrate the existing materials with the two-dimensional materials,” he said.
Mr Choudhary said the technology needed more work before it would become readily available, but these findings were a step in the right direction.
“For small electronic devices, our materials are surpassing the conventional ones worldwide in terms of energy density, power density and cyclic stability,” he said.
