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

In recent years, the new energy vehicle industry has developed rapidly. Among them, ternary lithium battery electric vehicles with high driving range have developed more rapidly and become the main force in the market. However, extreme joy begets sorrow. Spontaneous combustion and fire of electric vehicles occur frequently. The safety of electric vehicles has aroused great attention of the public. On September 21, Mr. Chen in Hangzhou drove the Zhidou D2 electric car rented from Xiaolingou Car Rental Company. Su

Recently, Roland Berger shared the latest Research Report on 2018 Global Electric Vehicle Development Index released in August with the auto headline APP. The report points out that China is still in the leading position in the 2018 global electric vehicle development index. The production of electric vehicles and batteries in China is growing rapidly and expected to be high, and continues to maintain a leading position in the "industry dimension". In the next few years, China is expected to maintain i

In recent years, China's new energy vehicle industry has forged ahead under the dual advantages of policy and market, and the power battery, as its core component, has also received increasing market attention. As we all know, the core technology of new energy vehicles is "three electrics", namely battery, electric control and motor. As one of the three core components of electric vehicles, battery bears the heavy responsibility of electric vehicle range, and lithium iron phosphate and ternary lithium

The requirement of energy density promotes the upgrading of batteries and puts forward higher requirements for materials such as positive and negative electrodes. However, when the materials are gradually mature, the application has been delayed. The main reason is that after various materials are combined into batteries, problems such as compatibility and safety of the system have not been well solved. At present, the technology level is gradually mature and the equipment is highly modernized. The focus of these p

At present, the development of pure electric vehicles has been shackled by the low battery energy density. Without a major breakthrough in battery energy density, the range of pure electric vehicles cannot be greatly improved. The development of pure electric vehicles will rely on policy support and lack market momentum. Recently, Ningbo Institute of Materials Technology and Engineering, Chinese Academy of Sciences announced that the project of "all solid state battery", a leading nano project undertak

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
