Mica products are used as thermal runaway protection materials for power batteries in the new energy vehicle. Flame retardant mica is mainly used in battery pack, modules, battery top covers, cells area and busbars. With the increase of battery energy density, the safety problem of battery thermal runaway causing fire and explosion has become an important technical challenge to be solved urgently by new energy vehicle manufacturers
At present, the main protective materials for power battery thermal runaway are aerogel felt, flame-retardant foam, mica material, ceramic silicone rubber and so on. Mica is the main thermal isolation material to isolate the heat transfer between cells. Mica can maintain good insulation properties under the use environment of 500℃-1200℃. Mica plate has good bending strength and hardness, acid and alkali resistance, aging resistance, can be processed into various shapes, at high temperature does not produce toxic gases.

Mica tape for new energy

Mica tape for new energy

Descripción: With the rapid development of the new energy vehicle industry, power batteries as the heart of new energy vehicles, battery capacity, power output directly affect the performance of electric vehicles. The prerequisite for the power battery to achieve high performance is to ensure safety. Nowdays, the development trend of power storage technology is growing day by day. As an important material, fire-resistant mica products are widely used in energy storage batteries. It has excellent heat resistance and insulation properties, which can effectively improve the safety and performance of the battery. This artical introduces the key role of fire-resistant mica tape in energy storage battery. Fire-resistant mica products act as insulation in batteries. High temperature is a common problem in energy storage batteries. When a battery runs for a long time or charges and discharges quickly, it generates a lot of heat. Mica products are fire resistant and high temperature resistant, and if there is no effective insulation material, the heat will cause the battery to overheat, which will affect the performance and life of the battery. Heat-resistant mica paper can effectively isolate the heat inside the battery, prevent the heat from being transmitted outward, and maintain the stable operation of the battery. Fire-resistant mica tape acts as an insulating material in the battery. The battery contains a large number of positive and negative electrode materials, if the direct contact, will lead to short circuit of the battery, and may cause serious safety accidents. Fire-resistant mica tape has good insulation properties, can effectively isolate positive and negative electrode materials, prevent current short circuits, and protect the safe operation of the battery. Fire-resistant mica tape can also provide mechanical support and fixation. In the energy storage battery, the positive and negative electrode materials need to be fixed together to ensure the structural stability of the battery. Fire-resistant mica tape has certain mechanical strength and flexibility, which can provide good support and fixing effect, and keep the overall structure of the battery stable. In summary, Fire-resistant mica tape plays a key role in energy storage power batteries. It can heat and insulate, while providing mechanical support and fixing effect to ensure the safety and performance of the battery. With the continuous development of power storage technology, fire-resistant mica tape, as an important material, will play a more important role in the future battery field.
