Why buy a lithium-ion battery electric car?

Explain the benefits of lithium-ion batteries! Recently, many of my friends around me have bought lithium-ion battery electric vehicles. We heard from the boss what are the benefits of such electric vehicles. In fact, after listening to what they said, I think this is not very scientific. Although they are all talking about the benefits of lithium-ion batteries, many bosses try to instill wrong concepts into customers and mislead them. Today, lithium-ion battery manufacturers will scientifically tell you the benefits of lithium-ion batteries, why you should buy lithium-ion battery electric vehicles: the first is light weight: polymer batteries of the same capacity are 40% lighter than steel-case lithium-ion batteries, The aluminum shell battery is 20% lighter. Secondly, small size: Ordinary liquid lithium-ion batteries adopt the method of customizing the shell first, and then inserting the positive and negative materials. The thickness can be less than 3.6mm, which is a technical bottleneck. Polymer batteries do not have this problem. The second is large capacity: polymer battery is 10~15% higher than steel shell battery of the same size and 5~10% higher than aluminum shell battery. It is the battery of choice for color screen mobile phones and MMS mobile phones. Most of the new color screen and MMS mobile phones on the market now also use polymer batteries. And the internal resistance is small, and the resistance of polymer batteries is smaller than that of liquid batteries. At present, the internal resistance of domestic polymer batteries can even be less than 35m, which greatly reduces battery power consumption and prolongs the standby time of mobile phones, which can reach international standards. The polymer lithium-ion battery supports large discharge currents and is ideal for remote control models, and is the most promising alternative to nickel metal hydride batteries. Shape can be customized: polymer batteries can be added or reduced according to customer needs. A new type of battery with low price and short mold opening cycle can be developed. Some can even be customized according to the shape of the mobile phone to make full use of the battery shell space and increase the battery capacity. The guard plate design is simple: due to the use of polymer materials, the battery will not catch fire or explode, and the battery itself has sufficient safety. Therefore, the protection circuit design of polymer batteries can consider omitting PTC and fuses to save battery costs. Good discharge characteristics: Polymer batteries use gel electrolyte. Compared with liquid electrolytes, gel electrolyte has stable discharge characteristics and a higher discharge platform. In summary, one of the most important features of lithium-ion batteries is safety: lithium polymer batteries are structured with aluminum-plastic soft packaging, which is different from the metal casing of liquid batteries. When faced with safety hazards, liquid batteries are prone to explosion, while polymer batteries can only be equipped with air drums.
