Scientists have discovered how to make a smartphone charge in seconds, by developing new flexible super capacitors that can be recharged more than 30,000 times without degradation.
After 18 months or so, smartphones hold charge for less time as battery begins to degrade.
Novel method could revolutionise technology as varied as mobile phones and electric vehicles.
Researchers experimented with applying newly discovered 2D materials only a few atoms thick to super-capacitors.
Other researchers have also tried formulations with graphene and other 2D materials, but with limited success.
There have been problems in ways people incorporate two dimensional materials into existing systems.
Scientists have developed a simple, chemical synthesis approach so we can nicely integrate the existing materials with the 2D materials.
Researchers have developed super capacitors composed of millions of nanometer thick wires coated with shells of 2D materials.
A highly conducive core facilitates fast electron transfer for rapid charging and discharging.
Uniformly coated shells of 2D material yield high energy and power densities.
Recent formulations of super-capacitors with 2D materials can be recharged a few thousand times.
In contrast, the new process yields a super-capacitor that does not degrade even after it has been recharged 30,000 times.
Super capacitors use new materials that could make phones, electronic gadgets, electric vehicles benefit from power and speed
As these are flexible, it could mean an advancement in wearable technologies as well, researchers have said.
