New power battery coating technical indicators: Escort battery performance

With the vigorous development of the new energy industry, power battery as a core component, its performance and safety have attracted much attention. As a key material to protect the battery, the improvement of its technical indicators has become an important part of promoting the progress of battery technology.

Insulation performance is one of the key technical indexes of new power battery coatings. In the process of charging and discharging, the battery needs good insulation performance to prevent current leakage and short circuit accidents. The new coating technology greatly improves the insulation resistance of the coating by optimizing the formulation and process, which can effectively isolate the current inside the battery and ensure the safe and stable operation of the battery in a variety of complex environments. The experimental data show that the battery using the new insulating coating reduces the risk of short circuit by more than 50%, which greatly improves the safety of the battery.

Thermal conductivity is also an important indicator of new power battery coatings. When the battery is working, a lot of heat will be generated, and if it cannot be dissipated in time, it will affect the performance and life of the battery. The new coating has good thermal conductivity and can quickly conduct the heat generated inside the battery to keep the temperature of the battery within a reasonable range. This efficient heat dissipation capacity can increase the charge and discharge efficiency of the battery by 10%-15% and extend the service life of the battery.

Corrosion resistance is another important standard to measure the quality of power battery coatings. During the use of batteries, they will be eroded by various chemicals, such as acids, alkalis, salts and so on. The new coating technology can effectively resist the erosion of these chemicals by adding special corrosion resistance components to protect the battery casing from corrosion. After corrosion resistance testing, the battery housing with the new coating has an extended service life of 2-3 years in harsh environments.

In addition to the above key indicators, the new power battery coating has also significantly improved in adhesion, wear resistance and other aspects. Good adhesion ensures that the coating can be firmly attached to the surface of the battery housing, and is not easy to fall off; High wear resistance ensures that when the battery is impacted by external forces, the coating can remain intact and continue to play a protective role.

The realization of these new technical indicators of power battery coatings is inseparable from the continuous research and development and innovation of coating manufacturers. By continuously improving the formulation and optimizing the process, they provide more high-quality coating products for the power battery industry.

However, in order for these new coating technologies to be widely used in actual production, there are still some problems to be solved. For example, the cost of some new coatings is high, and further cost reduction is needed to improve its market competitiveness; At the same time, it is also necessary to establish a unified industry standard to ensure the quality and performance stability of coating products.

In short, the improvement of the technical indicators of new power battery coatings has brought new opportunities for the improvement of battery performance and the development of the industry. It is believed that with the joint efforts of all parties, power battery coating technology will continue to progress and provide more powerful support for the development of new energy industry.
