Recently, researchers at Stanford University in the United States developed a new material combination that helps to create a rechargeable battery that can efficiently store a large amount of renewable energy generated by wind, solar, etc. With further development, this technology can deliver energy to the power grid quickly, at low cost and under normal ambient temperature. This technology is called mobile battery technology, which has long been considered as one of the options for storing intermittent renewabl

Entering the field of new energy vehicles has become one of the important paths for traditional energy enterprises to transform their energy structure. On the morning of August 30, Sinochem International (600500), a A-share listed company under Sinochem Group, signed an investment cooperation intention agreement in Shanghai with Huai'an Junsheng New Energy Technology Co., Ltd. (hereinafter referred to as "Junsheng Battery") and Nanjing Bojun New Energy Automobile Co., Ltd. (hereinafter referred to

In recent years, China's electric vehicle industry has developed rapidly due to the dual "favor" of policies and markets, but electric vehicles also have their own worries, such as short range, long charging time, low cycle times and outstanding safety problems. Hydrogen fuel cell vehicles have become another driving force for local governments to promote new energy vehicles due to their long range, short hydrogenation time and cleaner environmental protection. At present, Shanghai, Guangdong, Shaanxi

With the rapid release of ternary power battery, the industry focuses on wet membrane. Little did we know that the dry process single pull diaphragm with continuously improved performance and cost advantage began to show the momentum of "counter attack". According to the survey data of GGII, since this year, the shipment of dry process single pull diaphragm used in power battery field has not grown as fast as that of wet process diaphragm, but there is still a certain growth year-on-year. The main reas

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
