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

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
