We have heard many times that smartphone manufacturers plan to use graphene battery in their smartphones, but no company has sold them yet. However, the situation may change very soon.
The American company Real Graphene is working on batteries with improved characteristics, and according to company representatives, they are almost ready for mass commercial use.
The main advantage of a graphene battery is that it charges very quickly.
Real Graphene CEO Samuel Gong noted that it takes about 20 minutes to fully charge a 3,000mAh graphene battery using a 60-Watts charger. This is several times faster than the modern batteries of most smartphones.
He added that most of the batteries used by modern smartphones withstand to 300-500 charge cycles without significant deterioration. And Real Graphene batteries can withstand about 1,500 cycles at the same capacity. Since the graphene battery generates much less heat, it stays cooler and so, it is safer.
The company claims that it provides its customers with a complete solution that includes a battery and a special chipset needed for charging. Although the company has not yet entered into an agreement with smartphone manufacturers, they started selling Real Graphene power banks.
A 10,000mAh version is offered for $90, and a 100-Watts power supply will cost only $15. A 20,000 mAh version is also expected. They do not work as fast as the future graphene batteries everybody is expecting but they still charge faster than the competitors.
