What is the real reason for lithium battery performance decline?

Source: 2020 - 04 - 05 13:08 hits: the real cause of the falls in the lithium battery performance of lithium battery is the most widely used batteries on the market at present, mobile devices are basically is to use the battery, but we also know that the lithium battery is not durable, long service life, there will be less and less use for a long time after use, power will reduce, so the reasons of the decrease of lithium battery, in order to study this problem, the national laboratory scientists are observed. Use of lithium battery charge and discharge at high magnification microscope observation, the real-time state of lithium battery charge and discharge. So what is the reason? Scientists observed that battery can produce pressure, electrode instability. Every charge and discharge cycle outside the electrode traces of lithium ions, which means that the lithium ion is dead, so it can't work again, so it can no longer be used when charging, it leads to a decline in capacity. In the process of observation, also found in the side will form a blocking phenomenon. Solid electrolyte layer on the electrode surface, which is the cause of the blockage, directly affect the battery charging capacity. Problem has been discovered, so how to solve it? If you want to fundamentally solve these problems, you must consider the nature of the battery, which is material. Or can find replacement elements. Now, scientists are looking for a breakthrough in development, lithium-ion battery the discovery of new materials, a new type of lithium battery research and development and the future, also can come true, instead of research and development has never stopped, these metal magnesium, aluminum battery is in violation of the I want to make a choice of life, rather than the lithium battery, but also in the experiment. New energy vehicles, booming demand for lithium battery before reporting the development of new energy vehicles, will promote the demand for lithium battery, but only industry speculation, but according to the latest information, a large number of lithium-ion battery production and trading platform, according to now because of the development of new energy vehicles, a surge in demand, the dynamic system of lithium-ion batteries is now in short supply, more related enterprises, according to the current lithium battery production technology barriers to some extent, in the next three to five years, power lithium battery market is still good, the first advantages highlighted production enterprises. Increasing, the demand for the new energy vehicles, or exploding, the companies that lithium battery or supporting materials influence the most direct company's technology advantage, their orders are exploding. According to the survey found that at present a lot of enterprises related to lithium battery has a concentration of research institutions. Lithium battery is in short supply on the market at present, the company overloaded production is also the choice of many enterprises. And related materials company said, the subsequent will strengthen the research and development, to meet customer demand, caught the core of the lithium ion battery technology is the core of new energy vehicles, so these companies in this industry than lithium batteries, lithium battery production, research and development of related materials, lithium mineral exploration and mining are these corporate research institutions. In the first quarter of 2015 is over. From the point of lithium battery shipments, there is a clear growth, compared with the first quarter of last year, production has a qualitative leap. Increased demand, and will continue to increase in the next quarter.
