High thermal conductivity? High insulation? Super soft. TIF thermal conductive silicone sheet solves the thermal management solution for new energy batteries

The power battery of new energy vehicles serves as the core power source of the entire vehicle. Its working stability, service life and safety performance are directly dependent on a highly balanced thermal management system. In lithium-ion batteries, during fast charging, high-load discharge and low-temperature start-up, the cells will continuously generate a large amount of heat. If the heat cannot be quickly dissipated and evenly distributed, problems such as excessive local temperature difference in the cells, increased internal resistance and accelerated capacity degradation will occur. In severe cases, it may even lead to thermal runaway, threatening the safety of the entire vehicle.

In response to the aforementioned industry challenges, a leading new energy vehicle manufacturer selected ZIITEK TIF thermal silicone sheet as the core thermal interface material between the battery cell module of the power battery pack and the liquid cooling heat dissipation plate. This solution addresses three core issues: heat dissipation, insulation, and protection, thereby comprehensively enhancing the safety performance and service life of the battery pack.

ZIITEK - TIF series is a composite thermal interface material specially developed for high power density and high insulation requirements scenarios. It precisely meets the application needs of new energy vehicle lithium batteries. Its core advantages are prominent:

- Wide range of high thermal conductivity, high heat dissipation and temperature control: The thermal conductivity ranges from 1.25 to 18.0 W/mK. It can be flexibly selected according to different battery pack power and heat dissipation requirements, quickly conducting the heat generated by the battery cells to the liquid cooling plate, significantly reducing the temperature difference of the battery cells, avoiding local overheating, maintaining the battery in the optimal temperature range, and improving charging and discharging efficiency and cycle life.
Excellent electrical insulation, eliminating short-circuit risks: With high breakdown voltage strength, it achieves electrical isolation between the battery cell and the heat dissipation structure, as well as between the module and the housing. It completely blocks leakage and short-circuit hazards, and is suitable for the high-voltage circuit environment of the battery pack, ensuring the electrical safety of the entire vehicle.
Super soft and highly elastic, fully filling the interface: The product features a high compression ratio, softness and elasticity, which can easily adapt to the uneven surfaces of the battery core and heat dissipation plates, as well as the tiny gaps. It completely eliminates the air insulation layer, significantly reducing the interface thermal resistance. At the same time, in the vehicle's driving vibration and bumping conditions, it provides buffering protection for the battery cells, reducing mechanical stress damage and safeguarding the structure of the battery cells.
Vehicle-grade fire safety with no additional bonding process: Achieves UL94-V0 high fire resistance level, extinguishes spontaneously upon contact with fire, and does not drip. This ensures the battery pack's fire safety from the material level; it has self-adhesive properties, eliminating the need for additional application of adhesives. Simply attach and install directly, simplifying the production line assembly process, enhancing production efficiency, and avoiding the increase in thermal resistance caused by adhesives.

Actual application scenarios and installation plans

Application areas
This application mainly covers the bottom and sides of the square battery cells/spherical battery cells modules of new energy vehicles, as well as the area between the module and the liquid cooling heat dissipation plate, and between the power devices and the shell inside the battery pack, achieving full-dimensional thermal insulation protection. Installation method
Relying on the self-adhesive property of the product, no additional auxiliary fixation is required. Simply attach the Mako TIF series thermal silicone sheet between the battery cell module and the liquid cooling plate, and press it moderately to achieve a firm attachment.
Applicable conditions
It can adapt to the wide temperature range of -40℃ to 125℃ for operation in new energy vehicles. It has undergone rigorous vehicle conditions tests such as high and low temperature cycling, long-term vibration, and high humidity, and its performance is stable without cracking, falling off, or performance degradation, continuously maintaining high thermal conductivity and insulation ability.

Application Effectiveness and Performance Verification
1. Significantly enhanced heat dissipation efficiency: Through on-vehicle testing, after installing the Mako TIF series thermal conductive silicone sheets, the battery module maintains an electric cell temperature difference within 2°C during continuous fast charging and high-load discharge conditions. The overall working temperature is reduced by 5-8°C, the interface thermal resistance is decreased by over 60%, and the heat dissipation efficiency is significantly improved. This effectively delays battery capacity degradation and extends battery lifespan.
2. Comprehensive electrical safety guarantee: The product's excellent insulation and withstand voltage performance fully meets the requirements of automotive-grade electrical isolation. After being tested by a third party, the breakdown voltage strength meets the standards, and there are no leakage or short-circuit faults during long-term use. It completely avoids circuit safety risks.
3. Outstanding buffering and protective effect: After the vehicle undergoes tests on bumpy roads and impact conditions, the electric cells have no mechanical damage or displacement. The soft and elastic material effectively absorbs vibration and impact forces, reducing internal stress in the module and enhancing the overall vibration resistance of the battery pack.
4. Compliance with fire safety standards: It has passed UL94-V0 fire resistance certification, meeting the fire resistance standards for new energy vehicle batteries. In harsh conditions, it can effectively prevent the spread of fire, providing additional safety for the entire vehicle.
5. Optimization and upgrade of assembly efficiency: The self-adhesive design eliminates the need for additional bonding processes, making the production line assembly more convenient and reducing labor costs and material costs. At the same time, it avoids the problem of uneven thermal resistance caused by traditional bonding processes, ensuring consistent heat dissipation performance.
