Industrial change will be triggered -Lithium - Ion Battery Equipment
At present, lithium batteries are the most used in this field. Lithium batteries were first commercialized in 1991, and later became the standard configuration of electronic equipment. But many people think the technology has reached its limit and want to find alternative sources, so graphene batteries have entered people's attention. It is reported that graphene is extremely conductive and durable, and scientists are looking for a variety of applications for this material.(Lithium - Ion Battery Equipment)
Recently, Samsung Electronics' research and development department successfully synthesized a "graphene ball" that can be used to extend the life of lithium batteries and speed up their charging. The graphene ball material can increase battery capacity by 45% and charge up to 5 times faster.
Samsung said that if the existing lithium battery needs to be fully charged in 1 hour, after adopting this new technology, it can be shortened to 12 minutes, and the lithium battery using graphene balls can also maintain the temperature at 60 degrees Celsius, which is in line with the requirements of electric vehicles. Requirements.
According to the data, graphene battery is a new energy battery developed by using the characteristics of lithium ions rapidly and massively shuttle between graphene surface and electrodes. The new battery compresses hours of charging time to less than a minute.
Seeing the application prospects of graphene, many countries have established graphene-related technology research and development centers to try to commercialize graphene, and then obtain potential application patents in the fields of industry, technology and electronics. The European Commission regards graphene as a "future emerging flagship technology project", formulates a special R&D plan, and will allocate 1 billion euros in funding over the next 10 years. The UK government has also invested in the establishment of the National Graphene Institute (NGI), which aims to bring the material from the laboratory to the production line and to the market in the coming decades.
my country also has unique advantages in graphene research. From the production point of view, graphite, which is the raw material for graphene production, has abundant energy storage and low price in my country. In addition, mass production and large-scale production are the most important factors hindering the large-scale commercialization of graphene. In 2013, the Chongqing Institute of Green and Intelligent Technology of the Chinese Academy of Sciences announced that it successfully produced the first 15-inch single-layer graphene in China by chemical vapor deposition, and successfully applied the graphene transparent electrode to the resistive touch screen, and prepared 7-inch graphite. ene touch screen.
Many terminal manufacturers are also very concerned about the innovation in the battery field. Huawei, the third largest mobile phone company in the world, started to develop graphene batteries as early as 2015. Huawei has announced that it will cooperate with the University of Manchester to study the application of graphene, and this project The research results can also be directly applied to consumer electronics and mobile communication devices.
At present, my country has successfully achieved mass production of graphene-modified high-energy-density lithium-ion supercapacitors. According to the Ministry of Industry and Information Technology, following the operation of the 500-ton graphene microchip production line in Ningbo, Ningbo CRRC New Energy Technology Co., Ltd. and the Ningbo Institute of Materials, Chinese Academy of Sciences jointly developed graphene-modified high-energy density lithium-ion supercapacitors. Recently passed the appraisal of new products organized by Ningbo Economic and Information Commission.
Experts believe that the use of graphene-modified cathode composite materials and graphene-modified composite conductive agents to develop high-energy-density lithium-ion supercapacitors has overcome the key technologies to ensure the structural stability of lithium-ion capacitors and improve electrode density. The product monomer capacity reaches 17kF, the energy density reaches more than 20Wh/kg, and the power density is close to 8kW/kg, and the overall technical level has reached the international leading level.
