500kwh battery for energy storage.South Korea develops new graphene ball battery

　　According to foreign media reports, Tesla’s Powerpack system project in South Australia has received widespread attention in the media. Elon Musk has promised that it will take 100 days to build a lithium-ion power plant in South Australia, otherwise it will be free for use. It turns out that Musk turned this promise into reality, and the power plant has become the most powerful battery system in the world.

　　When a thermal power plant in Australia encountered a power shortage last month, Tesla's battery system responded quickly and delivered power within milliseconds, impressing the public with its powerful power capacity. The successful operation of Tesla's Powerpack system inspired the neighboring state of Victoria, which also chose Tesla to deploy a large-scale battery system.

　　The Australian Financial News reported on Thursday that Tesla has been selected to build a 20MW battery system in the western state of Victoria to support its 204MW wind farm at the Bulgana Green Energy Center. The project is jointly supported by NectarFarmsfacility and the state government. Moreover, the construction time of this project is 18 months, which is much longer than the previous Powerpack system project.

　　The battery factory established by Tesla in Australia once attracted attention, and Musk is also committed to this aspect. Here, the editor would like to ask, I have all the money ready, when will the agreed model 3 mass production plan be fulfilled? It is said that Tesla has repeatedly lowered its production target for Model 3 electric vehicles. For details, please see "Tesla once again lowers its production target for Model 3 electric vehicles."

　　South Korea develops new graphene ball battery

　　According to the website of the Ministry of Science and Technology, South Korea's "Central Daily News" reported that a research team at Samsung Electronics Technology Institute successfully developed a new battery material "graphene balls" that have a charging capacity 45% higher than existing lithium-ion batteries and a charging speed Improved by more than 5 times. The research and development results were published online in the journal Nature Communications.

　　Researchers have discovered that after adding silica to the high-strength, highly conductive graphene material, graphene can be synthesized in large quantities. The synthesized graphene exhibits a three-dimensional shape like popcorn, so it is called "graphene ball" , using this graphene ball material as anode protective film and cathode material for lithium-ion batteries can increase charging capacity, shorten charging time, and ensure high-temperature stability.

　　Graphene has always been considered a representative material among the new generation of materials. Graphene peeled from graphite is a thin film of carbon atoms, which is characterized by high physical and chemical stability. The material is 100 times more conductive than copper and more than 140 times faster than silicon. This is why graphene ball batteries charge five times faster than existing rechargeable batteries. South Korea plans to commercialize "graphene ball" lithium electronic batteries within five years.

　　Xiantao Co., Ltd. invests 3 billion in hydrogen energy and battery recycling

　　At noon on January 5, Shenzhen Xiongtao Power Technology Co., Ltd. (hereinafter referred to as the "Company") announced that the company plans to sign an "Investment Cooperation Agreement" with the Datong Municipal People's Government and plans to invest in the construction of Xiongtao Power Supply Technology Co., Ltd. in Datong City, Shanxi Province. The Tao Hydrogen Energy Datong Industrial Park project has an investment amount of no less than RMB 3 billion; the company plans to sign an "Investment Agreement" with the Hubei Chibi High-tech Industrial Park Management Committee to invest in the construction of green battery recycling and reuse projects in the park and other related matters A consensus on cooperation was reached, and the company promised to invest RMB 1 billion within 2 years after acquiring the project land.

　　It is understood that the Xiantao Hydrogen Energy Datong Industrial Park project is mainly engaged in: hydrogen fuel cell catalysts, proton exchange membranes, stacks, battery control systems, hydrogen fuel generator systems, hydrogen storage systems and hydrogen production systems, as well as hydrogenation stations and other fields. Product development, production, operation and sales. After the project is fully put into operation, the output value will be no less than 15 billion yuan and the tax paid will be no less than 1.5 billion yuan. Build a hydrogen fuel engine system production base with an annual production capacity of no less than 50,000 units within 3 years; promote no less than 3,000 hydrogen fuel vehicles within the city within 2 years, and promote no less than 5,000 hydrogen fuel vehicles throughout the province Fuel the entire vehicle.

　　Vision Holdings believes that this cooperation will be conducive to being based on the national hydrogen energy policy environment, relying on the regional automobile industry foundation, giving full play to the overall resource advantages of Vision's hydrogen energy industry chain, and promoting the hydrogen energy industry of all parties to move towards more mature development goals. . The "Investment Agreement" signed between Xiongtao and Hubei Chibi High-tech Industrial Park Management Committee can improve the closed loop of the industrial chain, promote resource recycling, and is conducive to Xiongtao's long-term development.
