In recent years, with the continuous improvement of the level of science and technology, people's requirements for the quality of life are also increasing, and the performance requirements of products are getting higher and higher. The emergence of graphene just meets people's needs, so its The application is getting wider and wider, let's take a look at it in detail.

1. mobile phone screen: currently on the market the mainstream of mobile phone screen material: glass, metal, plastic and so on. Among them, the shortcomings of glass and metal are: fragile, easy to scratch, not environmentally friendly; and the shortcomings of plastic is not resistant to scratch, not high temperature, easy to produce odor. As a new material, graphene has the characteristics of high strength, good toughness and light weight. Therefore, it is widely used in the protective layer of mobile phones.

2. Cars: With the development of society, people's demand for cars is also increasing. However, due to the increasingly stringent emission standards of traditional fuel vehicles, new energy vehicles have become the most popular means of transportation. The power system of new energy vehicles is pure electric, hybrid electric or fuel cell.

3. Battery field: As we all know, batteries are indispensable in our lives. The mobile phones and other electronic products we use every day require batteries. Traditional lithium batteries have low energy density, short life, long charging time, and safety performance. Poor and other issues, these issues have seriously affected our lives. Therefore, how to improve the capacity of lithium-ion batteries and extend their service life, it has become a hot topic of current research, and in these aspects, graphene has a great role.

4. Automobile field: now, cars have entered thousands of households and become a necessary means of transportation for every household. However, with the popularity of cars, traffic accidents also occur frequently, which brings serious threats to people's life and property safety. In order to reduce the occurrence of such accidents, the state has issued relevant policies to limit the number of fuel vehicles and encourage the development of new energy vehicles, new energy vehicles based on pure electric are favored by the majority of consumers.

5. Aerospace field: as a large space market in the world, China has always attached great importance to space exploration, and China also plans to launch a manned space station around 2024, which is undoubtedly a great promotion to China's space industry. At the same time, it also means that the development of China's aviation industry will also usher in new opportunities.

Graphene is a simple substance with a layered carbon atomic structure. It has excellent electrical, optical, and mechanical properties. It has a wide range of applications in materials science, micro-nano manufacturing, and electronic industry. It is called "black gold". Industrial development cannot be separated from graphene.
