China's battery seals market localisation process to speed up the new energy vehicle field for its biggest demand. Battery seals, also known as battery seals, is an important part of the battery, refers to the safety device used to seal the battery to prevent electrolyte loss. Battery seals have the advantages of good electrical insulation, friction resistance, high/low temperature resistance, and can improve the service life and safety of the battery, mainly used in the production of fuel cells, lithium-ion batteries, lead storage batteries and other products, in the field of new energy vehicles has a broad application prospects. Compared with overseas developed countries, China's battery seals industry started late, but the development momentum is rapid. Battery seals industry has high technical barriers, in the early stage of industry development, China's high-end products are mainly dependent on imports. In recent years, benefiting from local enterprises to enhance the strength of independent research and development, China's battery seals production technology breakthroughs, greatly improving the durability of the product, environmental adaptability and stability. In this context, the localisation process of China's battery seals market is accelerating. Battery sealing system as one of its core components, its performance, safety and durability is critical. The application of seals in the power battery system plays a key role in ensuring the stable operation of the system under various environmental conditions.
The raw materials for battery seals account for a relatively high cost, including fluoroelastomer, silicone, hydrogenated nitrile butadiene rubber and so on.
