Application of Mica Products in the Industry of New Energy Vehicles

Mica sheet is a composite material made from natural mica and silicone resin through a special process. It has excellent insulating properties and high-temperature resistance, with a fire-resistant temperature ranging from 500°C to 800°C and can maintain its performance stability even in high-temperature environments. In addition, mica sheet also take advantages such as low thermal conductivity, resistance to oil corrosion, eco-friendly and non-toxic.

With the increasing trend of the electric automobile market, the demand for battery separators and septa is rapidly expanding. Mica sheet with its special technical performance, plays a key role in battery modules. It is widely used between battery cells as a shielding isolation layer to effectively perform thermal isolation functions. In the event of thermal runaway in the battery, mica sheet ensures that high-temperature fumes are discharged through preset vents in an orderly manner, minimizing damage to the surrounding environment and facilitating the rapid diffusion of high-temperature flammable gases and heat. This protective measure is crucial for ensuring the safety of battery modules. Worldly famous electric automobile companies such as Tesla, Volkswagen, NIO, and XPeng have all applied mica sheets to the protection of different battery components. It is predicted that by 2025, the usage of mica materials in electric automobile battery will reach to 17.3 million square meters.

As the electric automobile market continues to expand, the demand for mica products will welcome rapid growth. Many domestic mica manufacturers have already begun to lay out their business in advance in order to take the lead in market competition.
