Adapted to the on-board power supply conditions of new energy vehicles, the TIS thermal insulation sheet helps batteries achieve long-term stability

Under the rapid development of the new energy vehicle industry, battery power has been continuously evolving towards higher energy density and higher power density. Simultaneously, the problem of heat generation during charging and discharging has become increasingly severe. If the large amount of heat accumulated during the operation of the battery pack cannot be effectively dissipated, it will not only cause the degradation of battery performance and shorten the cycle life, but also easily lead to thermal runaway, posing a major safety hazard. As the core interface material connecting battery cells and the heat dissipation structure, TIS thermal insulation sheet, with its excellent comprehensive performance, has become an indispensable key component in the thermal management system of new energy vehicle batteries. It builds a solid barrier for the safe and stable operation of battery power.

The internal structure of the battery pack for new energy vehicles is compact, with a large number of cells and a dense arrangement. Moreover, during actual driving, the vehicle needs to withstand complex conditions such as temperature fluctuations and vibration impacts. Traditional heat dissipation materials generally struggle to meet the dual requirements of high thermal conductivity and electrical insulation simultaneously. However, the TIS thermal insulation sheet accurately addresses this industry challenge. The product is based on high-performance organic silicon as the substrate, and is compounded with special thermal conductive ceramic powder, possessing both high thermal conductivity and reliable electrical insulation performance. It can not only quickly disperse the heat generated by the cells but also effectively block the electrical path between the cells and the heat dissipation structure, preventing short-circuit risks and achieving dual guarantees of heat dissipation and safety.

High thermal conductivity, more stable temperature control
The TIS thermal insulation sheet features excellent thermal conductivity efficiency, enabling rapid transfer of the heat generated by battery cells to the heat dissipation module and the vehicle's thermal management system. This ensures a uniform temperature distribution in the battery pack and keeps the temperature difference within a safe range. Under high-temperature conditions, its thermal conductivity remains stable and does not diminish. Even in harsh usage scenarios such as summer heat and long-distance high-speed driving, it can still provide high heat dissipation, delay battery aging, and extend the service life of the power battery. Additionally, the product has excellent resistance to temperature extremes, maintaining a stable form within the working range of -45°C to 200°C. It does not experience cracking or detachment due to thermal cycling, making it suitable for the long-term complex operating requirements of electric vehicles.

Reliable insulation, safer electricity
Electrical insulation safety is the core advantage of TIS thermal insulation sheets. The product has passed professional insulation performance tests and possesses high volume resistivity and high breakdown voltage. It can form a reliable insulation barrier between the battery and the metal heat dissipation structure, eliminating the risks of leakage and short circuit, and ensuring the safety of the battery pack's electrical system. In addition, the material is soft and has excellent compression recovery performance, which can closely adhere to the surface of the battery cell and the heat dissipation structure, filling in the microscopic gaps, and increasing the effective heat contact area, further enhancing the heat dissipation efficiency. Its excellent chemical corrosion resistance can resist the erosion of internal electrolyte and moisture in the battery pack, ensuring long-term stable and reliable performance, and meeting the requirements of the full life cycle of the power battery.

Customized adaptation, making applications more convenient
In terms of adaptability and assembly, TIS thermal insulation sheets support customized die-cutting and cutting. They can be designed with specific sizes according to the battery pack structure of different vehicle models, making installation simple and convenient, compatible with automated production lines, and significantly improving the production efficiency of battery packs. The product adopts a lightweight design, does not occupy additional space inside the battery pack, helps with the upgrade of vehicle lightweighting; at the same time, it has good vibration resistance performance, can effectively absorb vibration and impact during vehicle driving, avoid material damage and detachment, and ensure the long-term stable and reliable operation of the thermal management system.
