Graphene is used in the commercial smartphone called the Galapad Settler. Graphene makes its touchscreen more sensitive, colours appear brighter, and helps prolong battery life and standby time drastically.
Chongqing-based graphene researcher and maker Moxi teamed up with Shenzhen-based tablet maker Galapad to release 30,000 of the Android handsets at the beginning of March, according to their websites. Each device costs 2,499 yuan (US$399).
Graphene is used in in the 5.5-inch phone’s touchscreen, 3000-mAh battery and case, said a representative for Moxi who gave his name as Mr Wu.
The phone’s specifications are not good but not great. It runs off a 64-bit quadcore Snapdragon 410 processor along with 2GB RAM and has 16GB of internal storage. The device has a 8 megapixel camera and a 5MP camera on the front.
The touchscreens made with graphene are able to transmit more light, so can produce better colours and are more sensitive than conventional ones, Wu said.
The use of graphene in batteries raises the charge density by 10 per cent and extends the overall battery life by 50 per cent, he said.
According to Wu, the phone’s graphene-laden case is a far better conductor of heat than ordinary handsets, so the hottest its surface will get is around 35 degrees Celsius.
