Lithium ion battery is composed of positive and negative electrode sheets, adhesive, electrolyte and separator. In industry, manufacturers mainly use lithium cobalate, lithium manganate, lithium nickel cobalt manganate ternary materials and lithium ferrous phosphate as cathode materials of lithium ion batteries, and natural graphite and artificial graphite as cathode active materials. Polyvinylidene fluoride (PVDF) is a widely used positive electrode binder with high viscosity, good chemical stability and physical

With the launch of the national fuel vehicle sales ban schedule, the position of new energy vehicles has become increasingly stable. As the core power source of electric vehicles, lithium-ion batteries are increasingly sought after by the market. The fabrication of lithium ion batteries involves the selection and matching of materials such as positive pole, electrolyte, negative pole and diaphragm, and the selection of design parameters of electrode plates; The working process of battery involves chemical reaction,

Fuel cell vehicles are an important direction for the sustainable development of the future automotive industry and an important breakthrough for the transformation and upgrading of the global automotive and energy industries. At present, fuel cell vehicles are in the demonstration and promotion period, and the product cost and hydrogenation cost are still high. It is suggested to strengthen the research and development support of the fuel cell industry chain, establish national special support funds, or formula

Recently, the German Automobile Industry Association (VDA) announced that the German automobile industry will invest more than 40 billion euros before 2022 to accelerate the research and development of electric vehicles, and another 18 billion euros will be invested in the research and development of digital and networking and autonomous vehicle. At the same time, the car production of the factories set up by German car enterprises overseas is expected to increase by 3% this year to 11.6 million cars, while the car

The local government of Japan is currently studying whether the battery of electric vehicles can be used as a reliable backup power supply to meet the power demand in an emergency. According to foreign media, as one of the five largest energy consumers in the world, Japan is vulnerable to natural disasters such as tsunamis, typhoons and earthquakes. Any destructive natural disaster may bring the national energy supply into crisis. But at present, the Japanese government may have explored a new way to solve this

With the accelerated pace of technological innovation related to new energy vehicles at home and abroad, the industrialization of new energy vehicles is facing a stage of development. However, the process of industrialization is slow. The root cause is that the consistency between lithium-ion battery packs is difficult to meet the needs of new energy vehicles. Today, the lithium-ion battery balance scheme brings dawn to solve the consistency problem. The pace of innovation of new energy vehicle related technolog

According to Reuters, BMW reported that its operating profit fell 27% to 1.75 billion euros due to exchange rate factors and high R&D expenditure in the third quarter of this year. EBIT was lower than the 1.795 billion euros expected by Reuters analysts.(Lithium - Ion Battery Equipment) BMW said that despite the slight increase in sales, the operating profit margin of the automotive business narrowed to 4.4% from 8.6% in the same period last year, far below the target range of 8% - 10%. The rising prices of

Have you ever wondered if you can use clothes to recharge an outdoor hike without a power pack? On the 28th, a lecture entitled "New Intelligent Fabric" was held in Huxi Campus of Chongqing University. This invention can convert electric energy through fabrics such as clothes, effectively reduce the burden of external power supplies such as rechargeable treasure, and conduct interdisciplinary research and application in chemical, new materials, automation, etc. It is reported that the paper of this invent

Recently, a team led by Liu Shengzhong, a researcher of the Silicon based Solar Cell Research Group of the National Laboratory of Clean Energy, Dalian Institute of Chemical Physics, Chinese Academy of Sciences, cooperated with Shaanxi Normal University to make new progress in the growth and application of perovskite single crystal thin sheet materials. The relevant research results were published in Advanced Materials (Advanced Materials DOI: 10.1002/adma. 201601995). Perovskite materials are excellent photovolt
