What are the advantages of high temperature adhesive tape in new energy storage?
[2024-10-25]

High temperature adhesive tape has the following advantages in the field of new energy storage:

First, the high temperature resistance.

Adapt to high temperature environment

In new energy storage systems, such as lithium batteries, batteries will generate heat during charging and discharging. Especially in some high-power energy storage application scenarios, the temperature around the battery module may rise to a higher level. High-temperature adhesive tape can withstand these high-temperature environments, and generally its tolerance temperature can reach about 120℃-260℃. For example, in some outdoor large-scale energy storage power stations, even under harsh high-temperature working conditions such as direct sunlight in summer, high-temperature adhesive tape can still maintain good performance, effectively preventing the adhesive tape from melting and deforming due to high temperature, thus ensuring the stability of all components of the energy storage system.

Thermal stability ensures battery safety

Lithium batteries are sensitive to temperature, and high temperature may cause safety problems such as battery performance degradation and even thermal runaway. High-temperature adhesive tape can be used to wrap and fix the battery module, and its good thermal stability can reduce the influence of the adhesive tape itself on the battery due to decomposition or release of harmful substances at high temperature. When the battery temperature rises, it can keep its physical and chemical properties, avoid chemical reaction with battery materials, provide a relatively stable external environment for the battery, and improve the safety of the battery.

Second, the insulation performance

Electrical insulation effect

New energy storage equipment involves high voltage and high current, so good electrical insulation is very important. High temperature adhesive tape has excellent insulation performance, and its insulation resistance can usually reach a very high value, for example, it can reach more than 10 Ω/cm. In the energy storage system, it can be used to isolate the positive and negative connection parts in the battery module to prevent short circuit. For example, in an energy storage unit composed of a plurality of lithium batteries connected in series, the connection part between the battery tabs is wrapped with high-temperature adhesive tape, which can effectively avoid the short-circuit fault caused by the contact between the tabs or the interference of external conductive substances during the operation of the battery.

Advantages in complex circuit environment

The circuit structure in the energy storage system is complex, and there are many kinds of electronic components and circuits. The insulating properties of high-temperature adhesive tape make it possible to use in complex electromagnetic environment and resist the interference of electric and magnetic fields. It can be used to wrap wires, circuit boards and other components to reduce the influence of electromagnetic interference on signal transmission and control of energy storage system and improve the stability and reliability of the system.

Third, chemical corrosion resistance

Resist electrolyte corrosion

Lithium batteries contain electrolyte, which is usually composed of lithium salt and organic solvent and has certain corrosiveness. The high-temperature adhesive tape can withstand the corrosion of these electrolytes, and the materials and coatings on its surface can prevent the electrolyte from penetrating into the adhesive tape, thus avoiding the destruction of the adhesive tape structure. For example, in the process of battery packaging, high-temperature adhesive tape is used to seal and reinforce the battery shell, which can be in contact with electrolyte for a long time without corrosion, effectively prolonging the service life of the battery.

Adapt to different chemical environments

During the production and operation of the new energy storage system, other chemicals may be exposed, such as detergents for cleaning the battery surface and flux in the production process. The chemical corrosion resistance of high-temperature adhesive tape enables it to work normally in these complex chemical environments, and it will not deteriorate and lose viscosity due to contact with these chemicals, thus ensuring the integrity and functionality of the energy storage system.

Fourth, the bonding performance

Good adhesion ensures that parts are fixed.

High-temperature adhesive tape has strong viscosity and can be firmly adhered to the surfaces of various materials, such as metals, plastics, ceramics, etc. In the new energy storage system, it can be used to fix battery modules, circuit boards, heat sinks and other components. For example, in a compact energy storage cabinet, the battery module is firmly fixed on the bracket of the cabinet by using high-temperature adhesive tape, and even if vibration and impact occur during the transportation and operation of the equipment, the components will not easily loosen, thus ensuring the structural stability of the energy storage system.

Long-term viscosity guarantees system life.

Its viscosity can remain stable in the long-term use process, and will not be rapidly attenuated due to environmental factors such as temperature change and humidity change. During the whole life cycle of the energy storage system, the high-temperature adhesive tape can continue to play its bonding role. For example, the battery packs of some new energy vehicles are packaged and fixed with high-temperature adhesive tape. During the years of use of the vehicle, the viscosity of the adhesive tape can still ensure the relative position stability of the internal components of the battery pack.
