G-King graphene battery showed off in China, it charges phone just in 15 minutes

The excruciatingly painful experience of charging your phone well might be over if a Chinese company manages to put what it showed last week at an event in Beijing into reality. Dongxu Optoelectronic Technology has shown off its G-King graphene battery capable of charging a mobile phone just within 15 minutes instead of hours taken by conventional Lithium-Ion battery. The new battery is also seven times lighter than Li-Ion battery and remarkably flexible that can help pave the way for slimmer, lighter and bendable smartphones in the future.

Graphene has been a center of attention in many projects. In China, particularly, there has been an increased effort by smartphone manufacturers to utilize it in the path breaking innovations such as flexible displays and fast-charging batteries. Last week Dongxu Optoelectronic Technology unveiled G-King graphene battery at an event held in Beijing. The state news agency Xinhua went forth to mention it as "world's first graphene battery".

What is most exciting about this G-King battery is its lightning-quick charging ability. The company claims the new graphene battery only takes 13 to 15 minutes to recharge to the optimum level. This comes as an incredible improvement in charging time- about 10 to 20 times faster- compared to the conventional Lithium-Ion battery that requires hours to fully charge. The battery demonstrated was about the capacity of 4,800mAh, almost of the same capacity of a laptop battery. The battery can last up to 3500 charging cycles. Moreover, it is seven times lighter than the Lithium-Ion battery.

If the graphene battery is adapted to the consumer level, it can set off a revolution in the way present day's batteries work. The graphene batteries, as are flexible and ultra-lightweight, could prove to be game changing in altering the form factor of smartphones altogether. We could possibly see flexible, lighter, slimmer and bendable phones in the future. Going beyond phones these batteries can provide more and more power to electric cars, drones and many other devices since they discharge energy faster than the current technology that is being used.

Nevertheless, this is not the first time that graphene battery has been showcased. In the last two years on many occasions, the graphene-enhanced batteries have sprung up in public knowledge. So the news service Xinhua billing it as world's first graphene battery is little exaggerated. The tabloid claim could, however, become correct only if the G-King graphene battery move over from the concept or the prototype stage to the consumer level.

Tech in Asia reported the mainstream application of the new technology is still, "a long way off". But considering the massive scale of the show that Dongxu Optoelectronic managed to pull off at Beijing, we can assume the company has certainly made solid advances in making the new technology somehow closer to reality.
