Graphene products

Graphene frequently appears in various online topics. Some people render graphene and think that graphene can realize mass production of high-end chips and can be fully charged with 100% power in a few minutes when used on batteries. So what kind of material is graphene? Is the product made of graphene a high-tech or a hoax?

Application of graphene

On the topic of graphene, we can often see on the Internet that as a two-dimensional carbon material, it has a very wide range of applications. Take the semiconductor field for example. In September this year, it was reported that graphene was confirmed to be the material of the next semiconductor era. Using graphene as the material can break the limit of Moore’s law and produce 2nm chips.

The chip made of graphene is also called a carbon-based chip. Under the same process technology, the performance of carbon-based chips is several times that of the traditional silicon-based chips. Even graphene carbon-based chips can break through the unreachable 1nm process chip process.

Because graphene has a unique structure and excellent electronic properties. Almost all transparent materials are insulated, such as resin, diamond, and diamond, with the exception of graphene.

Its conductivity is very good, which makes graphene widely used in lithium batteries, superconducting capacitors, and other products. In addition, graphene is used in the powder field to make small-size high conductivity graphene powder. This kind of graphene powder product can act on heat dissipation coatings and retain the characteristics of high conductivity and heat conduction.

In addition, the application of graphene can be seen in graphene high-temperature sintering conductive carbon slurry, graphene thermal conductive silicone grease, and other corresponding product materials. Generally speaking, graphene plays an important role in a series of fields, such as micro-nano processing, aerospace, biomedicine, energy, and so on.

Since graphene was successfully extracted by Nobel laureates Andre Geim and Konstantin Novoselov, graphene has become a material of close concern all over the world. Due to the wide application of this material and its good performance, graphene has been “deified” by various.

It’s like using graphene to push global technology to a new year. It is undeniable that graphene materials have a wide range of applications, but whether they can achieve the corresponding properties or be popularized in a large area is another matter.

Is graphene a high-tech product or a scam?

In January this year, there was news about graphene batteries that deserves attention. The situation is like this. GAC group launched the self-developed graphene super fast-charging battery, which claims to be able to charge 80% in 8 minutes and then realize the endurance of hundreds of kilometers.

This matter has once again aroused widespread attention to graphene. Various news inconsistent with objective facts is everywhere. There are countless similar topics, such as what graphene will usher in the future of the next battery era, graphene will lead the new material technology revolution, and so on. So what’s the truth? Is graphene a high-tech product or a scam?

On this point, Ouyang Minggao, academician of the Chinese Academy of Sciences, hit the nail on the head. Ouyang Minggao said that if someone said that the graphene battery was fully charged in a few minutes, it was safe and the cost was low, then he must be a liar.

As academician Ouyang Minggao said, if someone really publicizes graphene batteries, chips, and other products with low cost and high efficiency, nine times out of ten are scams. Why?

The first is the cost. The price of a ton of graphene can be sold in tens of thousands or hundreds of thousands. Such expensive materials are difficult to be used in products on a large scale. Even if they are used, they are calculated in grams.

For example, for the battery known as graphene on the market, I’m afraid the content of graphene is only a few grams, and the component is still a common lithium-ion. Such graphene batteries are also sold at a high price of thousands of yuan. Under the excessive rendering of merchants, graphene is shaped at a low price, has excellent product performance, and can be fully charged in a few minutes. Most of these are fake.

The second is manufacturing. The extraction of graphene is not so easy. The efficiency of the mechanical stripping method is too low to realize industrial mass production. Although the oxidation-reduction method can have a good yield, the quality is reduced. Even if the extraction method with both production energy and quality is developed in the future, cost control is a big problem.

Therefore, graphene products on the market, as long as they are rendered into various high-tech by businesses, are likely to be scams.

At the current technical level, graphene is indeed widely used, but it is more realistic to expect graphene to realize a curve overtaking in the field of science and technology step by step.

Since graphene has these disadvantages, does it mean that we should give up the research and development of graphene and look for new materials again? It’s not. Everything has two sides. Graphene has the disadvantages of high cost and limited production capacity, but its main advantages are conductivity, strong thermal conductivity, and wide application.

In key areas, graphene materials can indeed play a corresponding value and role. But now too many people have prejudice and misunderstanding about graphene, and even boast too much. In the process of scientific and technological development, we should pursue seeking truth from facts.

Like what graphene battery is fully charged in a few minutes, and then the electric car can run hundreds of kilometers or 1000 kilometers. This is a complete scam.

The market prospect of graphene is still developing. Chinese people hope to see someone make a major breakthrough in graphene materials, but it is by no means unrealistic boasting. If graphene can become the core material leading the development of science and technology in the future, it is naturally a good thing. I just hope that businesses can be realistic at that time, which is enough.
