The researchers revealed a new type of battery that can be used to charge mobile phones or even electric vehicles in seconds. This new battery is called a miniature graphene supercapacitor and consists of a carbon layer that is only one atom thick, can be charged and discharged hundreds to thousands of times, and the charging speed is much faster than that of an ordinary battery. The size of the phone can be greatly reduced. The new battery is also very simple to produce, using a consumer-grade LightScribe DVD burner. The researchers said: "Using this technology, we can manufacture more than 100 such miniature ultracapacitors on a single disc using inexpensive materials within 30 minutes." The research team currently hopes to start cooperation with digital equipment manufacturers. "We are looking for industry partners to help us mass-produce this miniature graphene supercapacitor." 3PC ball valve,DIN flange ball valve,stainless steel ball valve Wenzhou Dico Valve Technology Co.,Ltd. , https://www.dicovalves.com
