The advantages and latest developments of graphene batteries

The graphene battery is a new energy battery developed by utilizing the characteristic that lithium ions rapidly shuttle between the surface of the graphene and the electrode. In recent years, the presentation of graphene battery technology has been favored by industry experts from all walks of life and has been placed on high expectations. So what are the advantages of graphene batteries? Please read the details below.

Nanotek Instruments, Inc. of Ohio, USA, has developed a new battery that utilizes the fast shuttle movement of lithium ions between the graphene surface and the electrodes. This new battery compresses hours of charging time to less than a minute. Analysts believe that the industrialization of fast-charging graphene batteries in the next minute will bring about changes in the battery industry, which will also promote innovation in the new energy vehicle industry.

Current status of new energy vehicles

With the promotion of policies and demands such as energy conservation and emission reduction, government subsidies, the current Chinese automobile market is ushering in the “golden age” of the development of new energy vehicles. In recent years, traditional car manufacturers have begun to be electrified, and there are more and more Internet electric car companies. The development trend of new energy vehicles is unstoppable. It is expected that the production and sales volume of new energy vehicles in China will continue to grow in the next five years, and it is expected to reach 3 million by 2020.

New energy vehicles and Internet vehicles look beautiful compared to traditional cars, but in the eyes of some car consumers, the high price, difficulty in charging, safety and driving performance and the gap between traditional fuel vehicles and other factors make them discouraged. . In this regard, some insiders suggested that in addition to the popularity of charging facilities, the development of new energy vehicles must be improved.

Current mainstream battery for new energy vehicles

The current mainstream new energy vehicle battery technology has been upgraded from the original lead-acid battery to the lithium battery technology, but the lithium battery still has technical bottlenecks that are difficult to break through. The battery life is short, the charging time is slow, and the energy density is low. Users often When you run into a low battery, you have to pick up the cart. Because of this, the creation of new materials for graphene and the new energy automotive industry will open the next vent.

Graphene battery advantage

Graphene has been praised by scientists as “the king of new materials”. It is a new type of nanomaterials known to humans with high strength, good toughness, light weight, high light transmittance and good electrical conductivity. It is applied to batteries and has battery charge and discharge. With the characteristics of fast time, high energy storage density and long battery life, experts in the industry place high expectations on graphene battery technology and become the focus of research and development of car companies and research institutions.

Graphene battery progress

The advantages of graphene batteries are not only helpful for the new energy automotive industry, but also for many other electrical batteries such as mobile phone batteries. It is understood that Zhuhai Polycarbon and Harbin Institute of Technology have established a graphene battery laboratory, which refers to automotive power battery technology. Currently, the energy consumption of graphene polymer battery is three times that of traditional battery products. Electric vehicles that use this battery to provide electricity can Driving over 1000 kilometers, and charging time is greatly reduced, the weight of the battery is less than half of the traditional battery. Although these data are still in the experimental stage, there is no doubt that graphene batteries will become a breakthrough point in the bottleneck of automotive battery storage.

Although graphene batteries have some exciting experimental phenomena and achievements in China, they are only in the theoretical exploration stage in the laboratory, and there are many problems in their manufacturing, processing and application efficiency. Therefore, the graphene battery is not yet able to meet the conditions of mass production, so it is temporarily impossible to replace the lithium battery.

Under the influence of the global environment, the development trend of new energy is unstoppable. With the influence of various factors, new energy vehicles will gradually replace fuel vehicles. At that time, the automobile and other related industries will bring about a big change.
