China develops graphene battery
A faster, more efficient graphene battery called ‘G-King’ has been developed in China.
Reports do not reveal how close the G-King, developed by Dongxu Optoelectronic Technology, is to mass production, but it could be the world’s first graphene battery.
The demonstrated graphene battery has a capacity of 4,800mAh, which is typical for batteries used in, for example, laptop computers. Dongxu showed the G-King’s super-fast charging time, taking just 13 to 15 minutes, when compared to several hours for charging conventional Lithium-Ion batteries.
This increase in efficiency is between ten and 20 times faster.
Dongxu says that the G-King graphene battery supports 3,500 charge and discharge cycles, which is currently around seven times more than Li-Ion batteries.
Graphene, the so-called ‘wonder material’, carries much disruptive potential. Batteries continue to be one of the main worldwide points of interest in research for further uses to add to an ever-growing list.
The European Union has invested billions of euro into graphene research through its future and emerging technology flagship pillar under the research and development framework programme, Horizon 2020.
