About the performance of lithium batteries

I want to talk about lithium batteries first. The battery is composed of a positive electrode, a negative electrode, a membrane, and an electrolyte. It is a device that can be charged and discharged, which makes our daily life essential. Such as 18650 battery, no. The battery in our lives is the 18650 model, and the Tesla car battery is also the 18650 model. To further improve the battery, the anode lithium compound of the lithium battery, the diaphragm electrolyte between the lithium battery, and the lithium ion reaches the cathode through the space shuttle, and is inlaid with graphite, and the discharge is de-embedded from the graphite and returned to the front side. , So there is electricity, this cycle battery can be recycled. The principle of the lithium battery is actually very simple. The earliest name is the rocking chair battery, which means that when it can be repeatedly charged and discharged, the lithium battery is a life. Of course, the standard for many car manufacturers for lithium ion suppliers is that the lithium battery is in My car has 2000+ cycles. What is the concept? If you buy an electric car and go to work in the city, you charge it three times a month on average and charge it 2,000 times a month, which means your car can last 12 to 7 years. Therefore, the country is now vigorously promoting new energy, and lithium batteries are also on the rise, which is a very promising prospect. Finally, I want to say that lithium batteries are also divided into soft pack batteries and ladle batteries. For example, Tesla vehicles use steel shell batteries, while other new energy vehicles basically use soft shell batteries, each with its own characteristics. Lithium batteries, we often say, there are actually three kinds of batteries, lithium metal batteries, lithium batteries, and lithium polymer batteries. I think you are asking about lithium batteries. At present, there are lithium iron phosphate batteries, ternary material batteries and lithium cobalt oxide batteries represented by BYD. Lithium iron phosphate, no matter what you are talking about, is the negative electrode material for batteries. According to the meaning, three of them are lithium nickel cobalt manganate. What kind of requirements do you have for lithium batteries? It is different from ordinary ones. 2. No. 5. Batteries, lithium batteries can be simply understood as batteries, which can be used for charging and discharging cycles. The appearance of common lithium batteries is cylindrical (for example, in the 18650 model, 18 refers to the diameter of 18 mm, 65 refers to the height of 65 mm, and 0 refers to the cylinder), square batteries, batteries, life is basically cylindrical Shaped, the 18650 model is the most common. Except for the positive electrode material, the other important materials of the cylindrical lithium battery are basically the same, including the separator material, the negative electrode material, the electrolyte, the steel shell, and the battery cover. Due to the difference of the cathode materials, the capacity of the voltage platform of the lithium battery of different cathode materials will be very different. For example, the voltage platform of a ternary lithium battery is generally 3.65v, while lithium iron phosphate is only 3.2v. At present, the energy density of ternary lithium batteries is better than that of lithium iron phosphate. However, lithium iron phosphate technology has encountered a bottleneck. Currently, lithium batteries used in electric vehicles are generally ternary lithium batteries. Lithium batteries are mainly used in two areas: first, mobile products such as mobile phones and computers account for about two-thirds of lithium battery usage; the second area is car batteries. The world is changing so fast, according to our 2010 data, there are almost zero lithium batteries for automobiles. This ratio now exceeds 30%, and it is likely to be added. The emergence of electric vehicles has opened up new application directions and new business opportunities for lithium batteries. Personally, I think the development of the high-quality electric vehicle industry is an objective requirement to effectively alleviate the pressure on energy and the environment, and it is urgent to better meet the rising people's need for a better life, and the strategic requirements to accelerate the car Industrial transformation and upgrading, fostering new economic growth points and advantages in international competition. With the phasing out of fuel vehicles, electric vehicles can only use lithium batteries in the future, so the development prospects are broad!
