US research institute improves lithium battery electrode technology

According to foreign media reports, a few days ago, researchers at Rensselaer Polytechnic Institute, the nation's top technology university, announced that it has successfully accelerated the charging rate of lithium ion batteries by using vanadium disulfide instead of cobalt oxide commonly used in electrodes.

"This material is lighter and has good conductivity, so it can meet higher energy density requirements and ensure faster charging speed." Nikhil Koratkar, the first author of the study, said, "Improved electrodes can enhance the performance of lithium-ion batteries. "

In order to promote the development of the new energy vehicle industry, global new energy vehicle companies have invested heavily in the lithium battery industry, and the leading position of lithium ion batteries is difficult to be broken. Various institutions are committed to lithium battery research, hoping to maximize the performance of lithium ion batteries before alternatives appear.

At the same time, in order to attract more consumers to abandon fuel vehicles and switch to electric vehicles, in recent years automakers and energy companies are launching ultra-high-speed charging equipment globally: in March, Tesla's world's first V3 super charging pile was put into use in the United States The maximum power is 250 kilowatts. On the most efficient Tesla models, it can achieve a one-minute charging range of 30 kilometers. The fast charging pile produced by the Australian company Tritium can meet the needs of charging for 10 minutes and driving more than 346 kilometers.

The industry pointed out that while discussing the charging speed, the ability of the battery itself is definitely the most inescapable factor. Regardless of the power and charging capacity of the peripheral charging equipment, if the battery itself has a shortcoming in acceptable charging capacity, the charging speed will inevitably be affected.

Erik Terjesen, senior director of Ionic Materials, said: "In view of the huge investment in the early stage, the new energy automotive industry is unlikely to abandon the lithium-ion battery and choose to" start from scratch. "We should increase the capacity of lithium-ion batteries, improve battery performance, try component improvements Rather than rush to find alternatives. "(Intern reporter Zhao Ying)

Stainless Steel Plain Dutch Weave Mesh, also known as wire mesh, it is made of high quality stainless steel wire. Similar to plain weave, it is weaved line by line. But for this kind of Stainless Steel Wire Cloth, the difference is the diameter of the weft is more thicker than the diameter of the warp. The weft wire is close together and then form a conical or wedge shaped hole. There is a big contrast between warp and weft wire diameter and density, so the net thickness and filtration precision and service life is significantly improved than common steel mesh. the filtering precision is running cannot be achieved for plain weave and Twill Weave Mesh screen.

Weaving:  There are two kinds of weaving technology of Dutch woven Stainless Steel Mesh . One is plain Dutch knitting and the other is twill Dutch knitting. The weaving technology of Dutch woven stainless steel mesh combines Dutch knitting and twill weaving techniques. The coarser thread interleaved the finer threads, weaving each thread through the weft. The weft wire is closely aligned to form a cone or wedge open hole.

Features: Dutch woven stainless steel mesh features 4 points:

              1."Zero" mesh, the warp wire diameter than the weft to the larger diameter.

              2. Each weft is very tight

              3. High precision, high liquidity

              4. Filter more solid particles than square or rectangular mesh holes

Material: 201,302,304 (L), 310,316 (L), etc

Application: The Dutch weave Stainless Steel Wire Mesh is one of the best filter medium in hydraulic system, especially the spatial filtering critical applications, as well as the fuel and combustion chamber filter, sediment filter, vacuum filter, etc.

       The warp wire (D1) : all longitudinal braided lines.

        The weft wire (D2) : all horizontal weaving lines.

        Aperture : the distance between two meridians or two weft.

        Mesh number:number of mesh holes per inch.

        Thickness (T) : thickness of wire mesh.
