New type of lithium battery, to solve the shortcomings of traditional lithium battery burst into flames low range

Source: 2020 - 04 - 01 sets hits: once the emergence of new type of lithium battery, solve the traditional lithium battery explosion fire range the disadvantage of low recently, a team of engineers at the university of Illinois in the United States claims to have developed a new kind of lithium battery. The battery will not fire, will not burst, at the same time can also significantly increase the durability of the battery device. It will be necessary smartphone battery technology in the future. This is not only a great breakthrough of the mobile phone, work is also the number and even the car is an important skill. Biggest advantage of this new technology is that it can effectively meet the challenges of the safety problems and battery life, at the same time improve the efficiency of the use of mobile phone battery, without significantly reduced the current capacity of the lithium ion battery power level. According to engineer, lithium ion batteries are based on solid polymer electrolyte, a self-calibration is recyclability. Now, lithium battery using liquid electrolyte, if the battery is serious damage or heated, it will react with electrodes. A lithium battery fire even burst. But by using a special cross-linking polymer, new electrolyte does not decompose when heated, but stronger. This means that the lithium battery will not fire or explosion when heated. However, lithium ion battery in the external heating or damage will not catch fire. But the university of Illinois, 伊利诺伊大学) Materials science and engineering graduate student Brian Jing pointed out that the solid polymer or ceramic electrolyte easily melt under the high temperature inside the battery, although they are now regarded as substitutes. In order to solve this problem, still need to use the crosslinked polymer chains to produce lithium conductor like rubber. Its service life is longer than solid electrolyte, but it does not correct itself, and it is difficult to restore. In order to solve this problem, a team of engineers at the university of Illinois have developed a method of manufacturing crosslinking key allows the solid polymer or ceramic electrolyte interaction and exchange of polymer chains. This makes polymer in heating hardened and self-correcting, so as to cut the growth of dendritic lithium dendrites. In addition, the polymer can be differentiated in the absence of strong acid or high temperature. Soluble in water at room temperature. So this new type of lithium battery does not affect the environment, environmental protection very much. The technology has not yet been commercialized, but a team of engineers at the university of Illinois, said they are doing their best to make its commercialization. Equipped with a new type of lithium ion battery cell phone will not fire, longer battery life.
