Lithium is an important driving force behind electric vehicles. Since 2021, concerns about the long-term imbalance between supply and demand of lithium and market speculation have led to the "soaring" price of lithium and the general price increase of electric vehicles. Can lithium supply keep up with demand in the future? We believe that new technologies and supply sources are expected to fill the supply gap.

Recently, Linfen Zhongbei New Material Co., Ltd. announced to build a smart factory project of lithium manganese iron phosphate material with an annual output of 10000 tons. The company said that the high coupling and integration of advanced manufacturing technology and advanced information technology will improve the whole process control and optimization capability of the production line and create a new model of smart lithium battery material factory. Stimulated by downstream demand, lithium battery material

The power lithium battery can be understood as a "sandwich" structure, consisting of positive and negative electrodes at the top and bottom, with a diaphragm sandwiched in the middle. The traditional liquid battery immerses the upper, middle and lower structures of the battery in the liquid electrolyte, while the semi-solid battery "extrudes" part of the liquid in the battery, and replaces part with solid electrolyte. When all the liquid in the battery is "extruded" and replaced with s

Since the birth of the first mobile phone, people have become increasingly dependent on it, especially in the era of Big Brother, which is a symbol of identity. Even the rich are flocking to it. However, when the technology has developed to a certain extent, the mobile phone industry has entered the era of functional machines. At this time, the production cost of mobile phones has decreased a lot, and the size of mobile phones has also been reduced to the size of the palm of the hand, almost everyone has one, and m

When it comes to batteries, most of my friends first think of products with narrow cylindrical shape like No. 5 battery and No. 7 battery. However, there is another type of battery in our life. Although it is smaller and less noticed by us, it still plays an important role. This type of battery is button battery. The size of the button is small. In the home calculator, on the main board of the desktop computer, in the small flashlight, and in the quartz watch on the wrist, the button battery is supplying energy. Th

Excessive charging of lithium battery may damage its internal structure and permanently reduce battery capacity. We may use LNMO spinel to improve this problem. The fluorescence analysis results show that the internal structure of the battery will be significantly damaged after only a few charges. UlrikeB&ouml, researcher of the German Institute of Electron Synchrotron (DESY); Dr. senberg and his team at the DESY X-ray synchrotron radiation source have directly observed the structural changes of lithium b

Under the background of the driving distance anxiety and the bottleneck of the breakthrough improvement of battery cell energy density, the lightweight design and application from the whole vehicle to the pack has become a topic of common concern for the main engine manufacturers, battery manufacturers and pack companies. According to relevant industry estimates, the range of new energy vehicles can be increased by 10% - 11% for each 100Kg weight reduction, and the battery cost and daily consumption cost can als

The use of cobalt has never stopped since ancient times. The ancient Greeks and Romans used it to make colored glass. The blue color on the famous three-color porcelain of the Tang Dynasty in China is also a masterpiece of cobalt. In modern times, cobalt and its alloy products have been widely used in many industrial fields, such as machinery, chemical industry, and even special aerospace. It can be said that today's cobalt has become a metal of great strategic significance. Cobalt is particularly importa

After the adjustment of subsidy policies, the development of new energy has shown a steady and continuous upward trend. In September, the retail growth of traditional fuel vehicles was - 14%, and the wholesale growth of new energy vehicles was 70%. New energy vehicles have become the core driving force driving the growth and increment of the car market. In September, the sales volume of new energy passenger cars in a narrow sense was 95000, up 68.6% year on year and 14.9% month on month; From January to Septembe
