With the rapid development of new energy vehicles, the power battery as the core component of new energy vehicles has gradually received widespread attention and importance. The performance and reliability of the power battery has a crucial impact on the overall performance and market competitiveness of new energy vehicles. As one of the important components of power battery, power battery structural sealant has contributed to the development and innovation of battery technology while ensuring the performance and reliability of new energy vehicle battery.
Power battery structural sealant is a polymer material with special adhesive properties, which has both high adhesive capacity and can well seal the inside of the battery to avoid the loss and leakage of liquid and gas inside the battery. In the new energy vehicle battery, the power battery structural sealant is mainly used for the bonding and sealing between the battery shell and the battery cover, which can effectively prevent the leakage of the internal material of the battery. At the same time, the power battery structural sealant also has good resistance to high temperature and corrosion, and can adapt to the harsh working environment.
The application of power battery structural sealant in new energy vehicle battery can not only improve the performance and reliability of the battery, but also can effectively reduce the cost of the battery. Due to the high adhesive capacity and sealing performance of power battery structural sealant, it can reduce the air pollution and material leakage inside the battery. At the same time, power battery structural sealant can also reduce battery cost, because it can not only reduce the damage and damage inside the battery, but also extend the service life and use time of the battery.
The selection and application of power battery sealant needs to consider a variety of factors, such as battery material, battery structure, working environment, application scenarios, etc. At present, the commonly used power battery structure sealant in the market mainly includes hot melt adhesive, silicone rubber, polyurethane and so on. Among them, silicone rubber has better performance of high temperature resistance and corrosion resistance, which is suitable for the occasion of harsh working environment, but slightly lacking in sealing effect. Polyurethane has a better sealing performance, but in the high temperature resistance, corrosion resistance, etc. performance is not good. Hot melt adhesive can provide better sealing performance and high temperature resistance, but under low temperature environment performance is not good.
In summary, the application of power battery structural sealant in new energy vehicle battery is of great significance, which can effectively improve the performance and reliability of the battery and reduce the cost of the battery. When developing the selection and application scheme of power battery structural sealant, it is necessary to consider various factors such as the working environment, application scenario and material performance of the battery in order to select the appropriate sealant material and application scheme to ensure the long-term stable operation and good performance of the battery.
