As the core component of new energy vehicles, the performance and stability of the battery directly affect the use of the vehicle. Therefore, the development of safer and more environmentally friendly battery materials has become an important research direction of the new energy automobile industry. Batteries are a widely used energy source that has become one of the infrastructures of modern life. Compared with traditional batteries, modern batteries have better performance, longer life and smaller size. However, the improvement of this performance is inseparable from the progress of battery materials.

1. Research on sodium ion battery materials

Sodium-ion batteries have become a new type of battery that has attracted much attention due to its rich resources and low cost. The electrode material of sodium-ion battery is similar to that of lithium battery, but the ion radius of sodium-ion battery is larger than that of lithium, which leads to the charge transport performance in the material is greatly reduced. Therefore, the research of sodium-ion battery electrode material is more difficult than that of lithium-ion battery.

2. Research on lithium air battery materials

Lithium-air batteries are a new type of battery, and their theoretical energy density is very high, so they are highly anticipated. However, because the working principle of lithium-air batteries involves the participation of a large amount of oxygen, it is difficult to obtain theoretical results for the study of electrode materials, so the repeatability and accuracy of laboratory results have also received serious attention.

3. Research on organic electrolyte materials

Organic electrolytes have become commonly used electrolytes in lithium-ion batteries because of their good conductivity and flexibility. With the introduction of new materials, not only the conductivity of the electrolyte has been improved, but also its high temperature resistance, stability and other characteristics have been improved.

4. Research on composite battery materials

Compared with a single type of battery, composite batteries such as lithium-silicon batteries have characteristics such as good rate performance, high capacity, and low cost, so they are becoming the future development direction of the new energy automobile industry.

5. Research on environmentally friendly battery materials

The rapid development of the battery industry has also led to the large-scale production of discarded batteries. Therefore, the study of environmentally friendly battery materials has become a hot spot. The development of environmentally friendly battery materials is not only reflected in the recyclability of the material itself, but also involves the production process and use process of the battery.

In short, the research and development of battery materials not only affects the development of new energy automobile industry, but also is one of the hot topics of modern science and technology. We look forward to the birth of better battery materials.
