What is the real reason for the degradation of lithium battery performance?

The real reason for the decline in the performance of lithium batteries Lithium batteries are the most widely used batteries on the market. Mobile devices basically use batteries, but we also know that lithium batteries are not durable and have a long service life. Long-term use will become less and less after use. , The power will be reduced, so the reason for the decline in the performance of lithium batteries, in order to study this problem, scientists at the National Laboratory of the United States made observations. A high-power microscope was used to observe the charging and discharging of the lithium battery, and the real-time status of the charging and discharging of the lithium battery was obtained. So what's the reason? Scientists have observed that the use of batteries will cause stress, causing the electrodes to rupture. Each charge and discharge cycle will leave traces of lithium ions on the outside of the electrode, which means that the lithium ions have died, so it can no longer work, so it can no longer be used when charging, which leads to a capacity loss decline. During the observation process, it was also found that a blocking phenomenon would form on this side. A solid electrolyte layer will be formed on the surface of the electrode, which is the cause of blockage and directly affects the charging capacity of the battery. The problem has been discovered, so how to solve it? If you want to solve these problems fundamentally, you must consider the nature of the battery, that is, the material. Or find an element that can be replaced. Scientists are now looking for breakthroughs in development. The discovery of new materials for lithium batteries, and the future development and use of new lithium batteries will also come true. Alternative research and development have never stopped. These metal magnesium and aluminum batteries are going against my hopes. The life of choice is not a lithium battery, but it is also in the experiment. The vigorous development of new energy vehicles has driven the demand for lithium batteries. The development of new energy vehicles reported previously will promote the demand for lithium batteries, but only industry speculation, but according to the latest information, a large number of lithium battery processing and trading platforms, according to Now due to the development of new energy vehicles, the demand has surged. The dynamic system of lithium batteries is now in short supply. More related companies, according to the barriers of lithium battery processing technology to a certain extent, in the next three to five years, the power lithium battery market will remain Good, at this time the first advantage of the processing company is prominent. The demand for new energy vehicles is constantly increasing, or is rising explosively, which has the most direct impact on the technical advantages of lithium battery companies or supporting material companies, and their orders are also explosively rising. According to the survey, many companies related to lithium batteries currently have a centralized research organization. At present, the supply of lithium batteries in the market is in short supply, and the company's overload processing is also the choice of many companies. And related materials companies said that they will strengthen research and development in the future to meet customer needs. Grasping the core technology of lithium batteries is the core of mastering new energy vehicles, so these companies are better than lithium batteries in this industry. Research and development related materials, lithium mineral exploration and mining are the research institutions of these companies. The first quarter of 2015 has passed. From the perspective of lithium battery shipments, there has been a significant increase. Compared with the first quarter of last year, the output has a qualitative leap. Demand has risen significantly and will continue to rise in the next quarter. Disclaimer: Some pictures and content of the articles published on this site are from the Internet.
