The most advanced battery in the world

Due to the development of new energy vehicles, electric vehicles have entered our lives accordingly, and with the strong subsidies from the national government, many people want to buy new energy electric vehicles, but after buying electric vehicles, they will inevitably worry about the batteries of electric vehicles. Today, Bian Xiao Auto will briefly introduce the most advanced batteries in the world to friends. Let's have a look!

Brief introduction of the world's most advanced batteries

It is 2-3 times smaller than ordinary lithium batteries, but it needs 2-3 times larger energy density.

In & ampLdquo high-tech project; Wulin congress; During the contest, experts from the 4th Science and Technology Fair gathered.

On September 22, at the science fair; Special conference on the release and trading of scientific and technological achievements and patented technologies; High-tech projects such as nuclear radiation detection system, multi-functional satellite command vehicle and smoke visibility detector have appeared one after another. Among them, one&; Ldquo super lithium battery &; Rdquo has attracted a lot of attention. Brief introduction of the field staff, this is&; Ldquo high specific energy lithium-sulfur battery and battery technology status: conservatively estimated to be 2-3 times smaller than ordinary lithium batteries, but its energy density needs to be 2-3 times larger, which can be widely used in new energy vehicles, mobile phones and other products.

Specific energy is the energy that can be released per unit weight or volume of the battery, and it is an important performance index of the battery. this &； Ldquo super lithium battery &; Rdquo is now the lithium-sulfur battery and battery pack with the highest specific energy in the world.

Brief introduction of the world's most advanced batteries

Lithium-sulfur battery is a kind of lithium battery. 20 13 years, this technology is still under study. Unlike lithium-ion batteries used in mobile phones and laptops, they are small partners of lithium batteries, but there are many differences in performance and charging and discharging principles. Lithium-sulfur battery is a lithium battery with sulfur as positive electrode and lithium as negative electrode.

Wang, a senior engineer at Dalian Institute of Chemical Physics, Chinese Academy of Sciences, said that compared with ordinary lithium batteries, lithium-sulfur batteries are smaller, the battery capacity can be increased by 2-3 times, and there is still room for improvement in the future. Researchers have developed a 35Ah battery with a specific energy of 566Wh/kg (measured at 25℃) and a 39Ah battery with a specific energy of 6 16Wh/kg (measured at 50℃), which are the lithium-sulfur batteries and storage batteries with the highest specific energy reported in the world. Moreover, sulfur is an environmental protection element and has no pollution to the environment.

Wang said: Lithium-sulfur battery. Now that it has passed the safety test, it may be widely used in civil fields such as new energy vehicles, mobile phones and tablets in the future.

At present, battery is the key to restrict the development of new energy electric vehicles, and this technical bottleneck is gradually being overcome. According to the public report of the reporter's inquiry network, the batteries on electric vehicles are bulky and heavy because of their low mass and energy density. Therefore, the number of batteries installed in each electric vehicle is basically very limited. For example, a battery pack of Tesla lies flat on the car floor, about 2 meters long and about 1.2 meters wide. In the top configuration mode, such a large power battery can only provide a driving distance of about 300 miles (482 kilometers), and then it needs to be plugged into a charging pile for charging.

The above is a brief introduction of all the most advanced batteries in the world by Bian Xiao Auto, and it is also a brief introduction of the most advanced batteries in the world. Bian Xiao Automobile Company briefly introduced A &；; Ldquo was exhibited for friends at the science fair. Super lithium battery &; From the above brief introduction, we can see that this kind of lithium battery has great advantages over ordinary batteries, and can be used in new energy vehicles and mobile phones, so it seems that in the future development,&; Ldquo super lithium battery &; Rdquo, it is not necessarily far away from us!
