Although in recent years, intelligent devices have been innovating and emerging in endlessly, the battery technology, which is necessary for every device, has been stagnant. The improvement of battery technology mainly depends on materials. People in the industry generally believe that graphene has great prospects in the chemical industry, including graphene batteries.

Recently, Samsung Institute of Technology published a paper entitled "Fast charging and super capacity battery through graphene ball" in Nature magazine, which pointed out that the research institute of Samsung Institute of Technology has synthesized a new three-dimensional solid material through silicon dioxide and graphene ball, which can significantly improve the characteristics of lithium ion batteries, Under the condition of constant volume The capacity of the existing battery can be increased by 45%, and the charging speed can be increased by 5 times. This special battery can not only be used for mobile electronic equipment, but also meet the battery standard of electric vehicles. It can be stably charged at 60 ℃. Samsung officials said that they had submitted patent applications for graphene ball batteries to the patent offices of South Korea and the United States.

Son In hyeok, a researcher at Samsung Technology Research Institute, said: "This research makes it possible to synthesize multi-functional and high crystalline graphene ball composites at low cost. This new large material can greatly improve the characteristics of lithium-ion batteries. We will continue to study this battery technology to meet the growing market of mobile devices and electric vehicles“
