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

Lithium metal batteries are "close relatives" of rechargeable lithium batteries, which are widely used in portable electronic products and electric vehicles. As the next generation of energy storage equipment, lithium metal batteries have great prospects. Now, a new study by researchers at Stanford University in the United States has pointed out a way forward for manufacturing better and safer lithium metal batteries. The relevant research was recently published in the Journal of the Electrochemical So

Recently, the latest ranking of the market value of auto manufacturers shows that BYD has surpassed Volkswagen Group with a total market value of US $129.23 billion and jumped to the third place in the list, becoming the only Chinese auto manufacturing company with a market value ranking among the top ten auto manufacturers in the world. On June 10, BYD's share price rose by more than 8% and closed at 348.80 yuan/share, with a total market value of 1.02 trillion yuan, officially breaking the trillion yuan thres

Recently, lithium battery innovation is quite lively. The demand is vast, the cost pressure is high, and the capital is crazy. The innovation impulse of lithium battery industry has never been so urgent. From 4680 batteries to solid-state batteries, from system innovation to local innovation, from material innovation to process innovation, where does this round of lithium battery innovation come from and where will it go? 01 Why is innovation urgent? At present, the lithium battery industry faces two ne

The combination of the two forms of Weilai charging and power change, combined with the convenient power-up under the intelligent location, has made the full-scene power-up network and user experience an unsurpassed moat for Weilai. On July 6, the 1000th NIO. US exchange station was officially put into operation in Lhasa, Tibet, with an average altitude of more than 4000 meters. Mr. Cai, who started from Hainan and headed west, became the first customer to place an order for the Lhasa exchange station. It tak

Why hasn't the sales of electric vehicles (EV) improved? The answers to the questions are still the same. Are we not enough? It's the battery, battery and battery of electric vehicles! Automotive engineers certainly know this, and material scientists are no exception. Although consumers seem to admire the achievements of TSLA (Tesla Motors), they do not understand why its successful experience in electric vehicles can not be extended to mid-level and entry-level vehicles. General Motors recently point

With the continuous breakthroughs in silicon material technology, semiconductor industry equipment manufacturing technology and key manufacturing process technology of photovoltaic cells, the beautiful vision of "sunshine everywhere, electricity everywhere" is closer and closer to our real life! In the past 20 years, the research results of photovoltaic scientists and photovoltaic cell manufacturing process technicians have reduced the cost of solar photovoltaic power generation from a few dollars/KWh to

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
