Recently, the research team of the State Key Laboratory of Biochemical Engineering, Institute of Process Engineering, Chinese Academy of Sciences developed a kind of sp hybrid nitrogen doped graphyne. It was reported that compared with other forms of nitrogen configurations, the introduction of sp hybrid nitrogen atoms makes the surrounding carbon atoms have more positive charges, which is more conducive to the adsorption and activation of oxygen, makes it easier for electrons to transfer to the catalyst surface, a

According to foreign media reports, in the past ten years, compared with coal and natural gas, the falling cost has made the competitiveness of solar panels and wind turbines gradually increase. Now this phenomenon also occurs in the battery, which also makes the price of electric vehicles decrease, and the grid can also store the required redundant electric energy. According to Wood Mackenzie's analysis, the cost of lithium-ion batteries has dropped by 75% in the past eight years in terms of per kilowatt ho

By the end of last year, the ownership of new energy vehicles in China had exceeded 1.6 million, accounting for 50% of the global ownership of new energy vehicles. This year's sales of more than one million should not be a problem. At the same time, the safety of new energy vehicles has become increasingly prominent, especially the fire incident has received extensive attention. On October 31, the person in charge of the Quality Development Bureau of the State Administration of Market Supervision answered a

On October 17, the "Sixth China South Korea Automobile Industry Development Seminar" was held in Beijing, with the theme of sharing experience in hydrogen energy and fuel cell vehicle industrialization, and building a hydrogen society in the future. Coincidentally, on the same day, in Jiashan County, Jiaxing City, Zhejiang Province, 1200 kilometers from Beijing in the south, the China (Jiashan) Forum on the Development and Application of Hydrogen Energy and Fuel Cell Industry (hereinafter referred to as t

Recently, new energy electric vehicles caught fire in many places in China, which has constantly aroused the market's attention to the safety of lithium batteries. In the face of the high price of battery raw materials and the decline of vehicle subsidies, battery manufacturers are facing the dual pressures of upstream and terminal. 2018 was widely believed by the market to be the first year for the large-scale application of high nickel 811. However, more than half a year later, with the price of cobalt, li

Volkswagen is firmly committed to the transformation to the field of electric travel. The Volkswagen brand released the "ELECTRIC FORALL" plan, which strongly promoted the breakthrough development of global electric vehicles. MEB modular electric drive platform is an important part of the Volkswagen brand electric vehicle offensive, which is specially designed for electric vehicles. Volkswagen Brand ID It will become the world's first model produced based on MEB platform; It will start production in Z

On October 27, the Ya'an High Energy Vanadium Battery Electrolyte Project Review Meeting was held in the Municipal Innovation and Entrepreneurship Incubation Center. Nearly 20 well-known experts and professors from the School of Chemical Engineering of Sichuan University, the School of Environmental Science and Engineering of Sichuan University, Sichuan Institute of Technology, the Central Research Institute of Dongfang Electric Group and other institutions of higher learning and scientific research conducted o

After the battery pack with the thickness of nail plate is cut, it does not explode and can still supply power normally; Bending for 10000 times, the battery capacity attenuation shall not exceed 5%; The appearance of solid lithium battery with high energy storage and significantly improved safety has shocked the battery industry. On November 19, Suzhou Qingtao New Energy Technology Co., Ltd., located in Kunshan, Jiangsu Province, officially put into production a solid state lithium battery production line that

As the "heart" of electric vehicles, power batteries are attracting as much attention as the current hot new energy vehicles. Among them, lithium ion batteries are favored by the new energy vehicle industry due to their high energy density, low self discharge rate, high cycle efficiency, long cycle life and other characteristics, and have huge market development potential. However, the current problem of unstable safety of lithium-ion batteries still exists. In addition, the frequent occurrence of batt
