Why do electric vehicles use polymer lithium batteries?

At present, most electric vehicles use titanium manganese polymer lithium batteries, which have the characteristics of high volume density, long service life, high repeated charging times and high consistency. If the fast charging mode is adopted, the vehicle can run 380 kilometers in only one and a half hours. It is an ideal power lithium battery energy. With the common development with the smart grid, electric vehicles are not only the product of advocating energy conservation and emission reduction, It can also play the role of micro and flexible charging and discharging devices and boost the development of renewable energy.

According to the national policy, if the necessary conditions for the promotion of electric vehicles, we must form an efficient, perfect and flexible charging and replacement service system. Considering that the electric vehicle industry involves many industries, especially the rechargeable battery industry, various policies have been implemented. At present, the main purpose is to strengthen the information communication and exchange between the electric industry and the lithium battery industry, so as to jointly promote the development of the electric vehicle industry.

However, many people do not know the principle of polymer lithium battery, so take this opportunity to understand the principle of polymer lithium battery: the main structure of polymer lithium battery includes three elements: positive electrode, negative electrode and electrolyte, and at least one or more of these three main structures use polymer materials as the main battery system. In the currently developed polymer lithium battery system, polymer materials are mainly used in cathode and electrolyte.

The cathode materials include conductive polymer or inorganic compounds used in general lithium-ion batteries. The electrolyte can use solid or colloidal polymer electrolyte or organic electrolyte. General lithium-ion technology uses liquid or colloidal electrolyte. Therefore, solid secondary packaging is required to contain combustible active components, which increases the weight and limits the flexibility of size. There is no excess electrolyte in the polymer lithium battery process, so it is more stable and not easy to cause dangerous situations due to overcharge, collision or other damage of the battery and excessive use. The principle of polymer lithium battery is provided by jiashidun technology.

The new generation of polymer lithium-ion batteries can be thin, arbitrary area and arbitrary shape in shape, which greatly improves the flexibility of battery modeling design, so that they can be made into batteries of any shape and capacity to meet the product requirements, providing application equipment developers with high design flexibility and adaptability in power source solutions, so as to maximize their product performance.
