In 2004, two meta-physicists at the University of Manchester successfully isolated graphene from graphite, the thinnest and strongest nano-material with excellent electrical and thermal conductivity ever discovered. As early as 2012, the American Institute of Electrical and Electronics Engineers (IEEE) concluded that graphene could lead the world into the carbon age by replacing silicon-based materials in the future, making it one of the brightest jewels in the materials industry. At the 2018 China International Graphene Innovation Conference held in September 2018, more than 200 promising graphene applications from around the world were collected, while Huawei Mate 20 X was claimed to be the world's first graphene cooled phablet and Samsung Galaxy Note 10 was expected to use a graphene battery that could be charged up in 12 minutes. According to a report by consultancy ReportsnReprts, the global graphene market is estimated to be nearly US$200 million in 2018, growing 84.8% annually, and the overall market size is estimated to be over US$1 billion in 2023. The Foresight Industry Research Institute was of the view that by 2020, graphene would account for approximately 50% of the applications in new energy fields such as lithium batteries. According to the 2017 Global Graphene Index, China, the United States and South Korea are in the leading echelon, with China coming first in terms of overall strength, but the gap between China and the US in second place is gradually narrowing.
