Anonymous users2024-02-14The University of Texas at Dallas and Seoul National University.
The University of Texas at Dallas and Seoul National University in South Korea have jointly developed a new battery that uses manganeseandsodium-ion-based material. The material may reduce the cost of batteries and be more eco-friendly, making batteries that can be used in electric vehicles.
They replaced lithium, the largest material in the anode, with sodium and replaced the more expensive and scarce cobalt and nickel with manganese. The research team adopted a reasonable ratio of raw materials and overcame the above technical problems. They used computer simulations to determine the configuration of the atoms at the optimal performance of the battery, and then carried out extensive material testing in the laboratory until the development was successful.
Massachusetts Institute of Technology (MIT).
According to foreign media reports, researchers from the Massachusetts Institute of Technology (MIT) and their German counterparts jointly proposed that if a solid electrolyte with a smooth surface is used, it can prevent harmful lithium penetration (liinfiltration), thereby improving the performance of solid-state lithium-ion batteries. According to the new analysis, the smoothness of the surface is the key to the problem, and microscopic cracks and scratches on the surface of the electrolyte will lead to the accumulation of metal.
After an electrochemical reaction, lithium (ions) from the electrolyte will begin to accumulate on its surface for subtle imperfections, including tiny pits, cracks, and scratches. This will continue once lithium ions begin to build up in the imperfections.
This suggests that researchers need to focus their research on improving the smoothness of the solid-state electrolyte surface, which may eliminate or greatly reduce the number of dendrites generated in the battery's solid-state electrolyte. In order to avoid flammability, solid-state lithium metal electrodes may also be used in the future. In addition, the move could double the energy density of lithium-ion batteries.
Tokyo Institute of Technology.
Researchers at the Tokyo Institute of Technology have developed a new technology solution, germanium-free solid-state electrolytes, that can reduce the cost of solid-state lithium-ion batteries and are working to apply the technology to electric vehicles, communications and other industries.
Germanium-free solid electrolyte.
The research team published in the journal "Chemistry of Materials" of the American Chemical Society (ACS)**, and its technical solution is to use tin and silicon instead.

Anonymous users2024-02-11The majors related to the lithium battery industry mainly include materials science and engineering, chemical engineering, chemistry, electronic information and other majors. Among them, the major of materials science and engineering is the study of the structure, properties and preparation methods of battery materials, the major of chemical engineering is concerned with the design, optimization and process control of battery production, the major of chemistry is the study of chemical reaction principles and electrochemical experiments, etc., and the major of electronic information is the study of the basic knowledge of physical disturbance, such as solid state physics, semiconductor physics, etc. When there is a problem with a lithium battery, you need to follow the following steps:
First, confirm whether the battery performance parameters match the specifications. Then, check for signs of short circuits or leakage and check the inside of the battery for wear, failure, and damaged battery parts. If the appearance of the battery is significantly deformed, the faulty part needs to be repaired or replaced.
Finally, the battery is tested and run using specialized equipment to ensure that the battery performance meets specifications. For personal tips, it is recommended to understand the correct understanding and use of lithium batteries, avoid the impact on the use of batteries in the process of charging and discharging, pay attention to the maintenance and repair of batteries, and avoid damage to batteries as much as possible. In addition, when buying a battery, pay attention to the brand and state model, and choose a reputable and guaranteed product.

If you want to enter a professional dance academy, you are a little late now, dear, generally enter a professional dance academy, you start practicing from a young age, that is, when you don't graduate from primary school, you go to a secondary school to study, because you learn dance, the younger you eat, the better, many people are nine or ten years old to enter a secondary school to learn dance, so that the basic skills will be very solid, and the possibility of going to a professional dance school is great, of course, unless your family conditions are good, spend some money to enter, because in the end, the people who compete with you are the children of professional colleges And all the children who learn dance have good family conditions, because the cost of learning dance for a year is very large, if you want to learn now, then hurry up and go to those secondary schools in Beijing to be a transfer student, after entering the practice hard, this will be much more likely, but in addition, you must learn cultural courses well, because the children in secondary schools have very good professional courses, but culture is not like this, because they are very young, they don't realize the importance of culture, so they often ignore In the end, the major has passed, and the culture has not passed, so there are a lot of people, what a pity If you want to learn hip-hop dance, then there is no need for what is said above Usually find a teacher to give you guidance and guidance And it seems that there is no school for street dance majors But if it is a national dance, then you have to do it as mentioned above And there is no kind of school with folk dance majors and street dance majors Anyway, ** National University did not Han Geng entered a secondary school at the age of 12 Later, when he was admitted to the university, he was admitted to the dance academy in the civil academy Technical secondary schools also have to learn cultural courses But the time for professional courses may be a little more than the time for cultural classes Because in recent years, the competitive pressure of dance has been very great, especially in a first-tier city like Beijing, a good professional college must not only have strength, but also have a background, with your current situation, or don't think about the private academy, you can go to the specialty students Specialty students are not the same as art students.

It's better to learn comics or Wang's education.
When choosing an educational institution, the first thing to look at is whether its main training business is the major you want to study, and you want a training institution that specializes in accounting to teach you comics, which is nonsense. Secondly, it is necessary to look at the teaching cases and student works of this training institution over the years, whether the style is rich or not, whether the strength is professional enough, and whether the learning guarantee model is comprehensive enough. In order to attract students, some small institutions with no strength rely on foolery and false propaganda, which can easily make beginners deceived, so you must remember: >>>More
