In recent years, the global new energy automobile industry is showing vigorous vitality and is about to usher in a stage of rapid development. At present, various countries around the world are making every effort to promote the popularization of new energy vehicles and introduce various favorable policies to help automakers make progress in new energy vehicles.
However, if new energy vehicles want to increase the speed of popularization, they must solve the two major problems of batteries and charging, especially batteries, which are the core components of new energy vehicles and related to consumer car experience.
American scientists make breakthroughs
In addition to the new energy vehicle industry chain, scientists from all over the world have joined the research and development of new energy vehicle batteries, which has also made a series of breakthroughs in battery technology.
On February 11, the Financial Associated Press reported that engineers at Drexel University in the United States have achieved a key breakthrough in battery technology, removing technical obstacles to large-scale commercial use of lithium-sulfur batteries.
In fact, lithium-sulfur batteries are also a kind of lithium batteries, which is one of the main research directions of scientists and new energy vehicle giants.
However, there are many technical problems in the commercial use of lithium-sulfur batteries, such as the introduction of sulfur in the battery, but due to technical limitations, after the sulfur enters the electrolyte, a chemical reaction will occur to produce sulfides, which will also affect the capacity and life of lithium-sulfur batteries.
Therefore, many scientists around the world are studying how to solve the problem of lithium-sulfur batteries.
It is worth mentioning that engineers at Drexel University in the United States brought a breakthrough technical solution, they redesigned a cathode, so that the cathode of the lithium-sulfur battery produces a substance called monoclinic gamma phase sulfur, and most importantly, this substance does not chemically react with the electrolyte inside the battery.
After a year of testing and research, the cathode developed by American engineers has undergone thousands of charge and discharge cycles, and the performance has not declined.
In addition, American engineers have only made a prototype of a lithium sulfur battery with a redesigned cathode, which has three times the capacity of conventional lithium batteries, in other words, this lithium-sulfur battery can provide longer endurance for new energy vehicles.
Lithium-sulfur batteries have obvious advantages
From the above point of view, lithium-sulfur batteries have a larger capacity than conventional lithium batteries, but this is only one of the advantages of the battery.
According to the author's understanding, the sulfur required for the manufacture of lithium-sulfur batteries is very easy to obtain, the cost is relatively low, as far as the current international market situation is concerned, the price of sulfur element is only one-sixtieth of the traditional lithium cobaltate.
Therefore, once the lithium-sulfur battery is commercially available on a large scale, it will inevitably replace most of the market demand for ordinary lithium batteries.
Not only that, the successful research and development of lithium-sulfur batteries is more conducive to the protection of the environment in various countries. As we all know, many batteries will cause great damage to the environment, and even some substances in the battery will pollute large areas of soil.
In contrast, the sulfur element in lithium-lithium batteries is very friendly to the environment, even after the lithium-sulfur battery is scrapped, the toxicity generated is not high.
To put it bluntly, lithium-sulfur batteries are currently the most environmentally friendly batteries, and they are also the best solution for new energy vehicles to use batteries.
Nowadays, American scientists have achieved breakthroughs in lithium-sulfur battery technology, which will further accelerate the popularity of such batteries in the field of new energy vehicles.
Write to the end
In recent years, the research on new batteries has emerged in an endless stream, such as sodium-ion batteries, titanium-ion batteries, etc., all want to replace traditional batteries through new batteries, but unfortunately, because of the limitations of many factors, most of the new batteries developed are either waist folded or cannot be mass-produced.
However, from many levels of consideration, lithium batteries are still the best choice in the current industry, and how to make technological breakthroughs in lithium batteries is the most important problem that major new energy giants need to study, and the above lithium-sulfur batteries are the best research directions.
Therefore, while vigorously developing the new energy automobile industry, the mainland should also conduct in-depth research on battery technology.
