Is graphene battery technology a black technology ? -Lithium - Ion Battery Equipment

Graphene is considered as a revolutionary energy storage material because of its strong electrical conductivity. In recent years, with the development of new energy vehicles and mobile communication equipment, using graphene to improve and enhance the performance of power and energy storage battery materials is becoming the focus of the industry.

In the field of new energy vehicles, the concept of "graphene battery" has been repeatedly mentioned, which seems to have become a breakthrough in the battery technology of electric vehicles. Graphene technology battery is known as "milestone black technology", which is claimed to be able to extend the range, battery life and shorten the charging time.(Lithium - Ion Battery Equipment)

However, along with the pursuit, the controversy has never stopped. Whether the "graphene battery" at the cusp of the storm is a concept hype or will really usher in a market opportunity still needs to be viewed objectively.

"Graphene battery" does not exist

The mixture of graphene materials and traditional battery materials can significantly improve battery charging and discharging, cycle life, etc. It has also become a winning point for power battery enterprises in the new round of market competition.

It is undeniable that the innovation and research and development of graphene application process has always been a problem that restricts the upgrading of battery related industries in China.

If graphene can effectively improve the capacity of power battery and realize rapid charging, it will directly hit the pain point of large-scale promotion of power battery, and it is of great significance for industrial upgrading of lead-acid battery industry. From this perspective, power batteries may be an opportunity for large-scale application of graphene.

After investigating and investigating the national graphene industry, we found that adding graphene as a basic material to existing battery materials has become a common practice of mainstream battery enterprises in China.

Graphene can be applied in three forms in the battery field: one is directly used as positive/negative materials; Second, as a conductive additive, it is added to the positive/negative electrode materials, or the electrode materials are composite modified to improve the electrode conductivity and charge discharge ratio; Third, as a collector or collector coating, it is used to improve the power characteristics of the battery.

At present, graphene is mainly used in lithium ion batteries in the latter two ways.

Because when graphene is directly used as anode material, its surface characteristics are easily affected by the outside world, its stability is extremely poor, and its efficiency is low for the first time, which is difficult to meet the performance requirements of lithium ion batteries.

Lithium ion battery, as an important part of the new energy vehicle strategic emerging industry, is a hot spot that investors are eager to pay attention to. It is inevitable for some groups to hype. But to be exact, there is no so-called "graphene battery" at present.

Previously, Dongxu Optoelectronics produced "olefin king" batteries, but it did not define any of its battery products as "graphene batteries".

Previously, the graphene lithium battery produced by Huawei once became popular. However, in the public information, graphene is only used as the heat dissipation material of Huawei's battery to improve the heat dissipation performance of lithium-ion battery, and it is not directly used to make the battery body.

Graphene can indeed improve battery performance, but it is mainly used as auxiliary materials (additives) in battery materials. As the most innovative new material in the 21st century, graphene has great application potential in the field of automotive batteries.

Graphene will have a bright future

As the thinnest, hardest and most conductive nano material, graphene has been in the forefront of scientific research and attracted much attention since its introduction in 2004.

The largest application area of graphene industry is composite materials. The composite material industry has a large volume and a wide range of applications, from special to civil. It can also be matched with the manufacturing materials of new energy vehicles, unmanned aircraft and electric yachts in the future.

In each segment of automobile industry, graphene has a huge market and business opportunities.

Taking the power battery field as an example, graphene is a promising anode and cathode material for lithium ion batteries. At the same time, the weight of graphene polymer battery is only 50% of that of traditional battery, and the cost will be 77% lower than that of lithium battery.
