Graphene batteries could make phone recharge times plummet

Chinese company Dongxu Optoelectronics has shown off a graphene battery pack that could recharge fully in just 15 minutes.

The G-King battery pack has a 4,800mAh capacity, which is more akin to a tablet or laptop battery than a smartphone, and can recharge in 13 to 15 minutes. Dongxu claims that the battery can be discharged and recharged 3,500 times, which it says is 7 times the strength of a conventional Li-Ion battery.

Aside from causing recharge times to plummet graphene battery packs could also make flexible screens possible and improve heart rate and fingerprint sensors.
