1 Application scenario of large-scale energy storage system In order to stabilize the fluctuation of output power, more and more new energy power plants, wind power plants or solar power plants are equipped with energy storage systems. With the reform of the electric power system, independent energy storage power stations have gradually entered people's vision, and independent energy storage power stations that make a living by reselling electricity have gradually emerged.(Lithium - Ion Battery Equipment)

The level of battery energy density is becoming an important factor determining the direction of subsidies for new energy vehicles. The subsidy of "low price retreat and high price rise" has promoted the upgrading of batteries and their materials. The ternary high nickel materials with high energy density and relatively stable price have become the best choice for battery enterprises. Ternary materials are gradually evolving towards high nickel. Many battery enterprises, such as Shenli Battery, Bike Batte

Despite the "cheat compensation" storm, the support of the decision-making level for new energy vehicles has not decreased. The recently held executive meeting of the State Council has determined five major measures to further support the new energy vehicle industry, including requiring central state organs, government departments and public institutions in cities where new energy vehicles are promoted to be used to increase the proportion of new energy vehicles purchased in the total number of vehicles e

Lithium ion battery is a complex system, including positive pole, negative pole, diaphragm, electrolyte, collector, binder, conductive agent, etc. The reactions involved include the electrochemical reaction of positive and negative poles, lithium ion conduction and electronic conduction, as well as the diffusion of heat. Therefore, the electrical performance and safety of lithium ion battery are affected by many factors. Therefore, the design and manufacture of lithium ion battery not only requires rich electrochem

According to foreign media, recently, Germany's Fraunhofer Institute of Environmental Security and Energy Technology developed a new "bipolar plate". The equipment can be used for bipolar battery, and the newly developed bipolar plate can save 80% of the material consumption.(Lithium - Ion Battery Equipment) According to the R&D personnel, the new bipolar plate uses conductive polymer, which has extremely thin physical properties, and can save a lot of material consumption compared with the tra

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

How to improve the energy density of lithium-ion batteries has always been the core content of lithium-ion battery research, especially in the aspect of cathode materials. In order to improve the specific energy, people are "unscrupulous". Therefore, a variety of cathode materials for lithium-ion batteries are emerging one after another, such as lithium rich manganese, ternary materials, etc. The specific capacity of some cathode materials has reached more than 200mAh/g, However, these cathode materials o
