* Question
What functions can the elastic layer enable?
* Answer
The elastic layer in an energy storage system is designed as a multifunctional element that goes far beyond simple spacing. It enables a range of critical functions that directly enhance the safety, reliability, and performance of the module:
High-Voltage Insulation and Protection
When the operating voltage exceeds 1 kV, the elastic layer can collapse in a controlled manner, forming an additional electrochemical insulation barrier between the housing and the internal cells.
This mechanism strengthens the system’s dielectric safety and minimizes risks of electrical breakdown or leakage current.
Tolerance Compensation and Structural Buffering
Due to its compressibility, the elastic layer effectively absorbs geometric dispersions caused by manufacturing tolerances or assembly variations.
This ensures even pressure distribution across the cells, prevents local stress concentration, and contributes to the long-term structural stability of the storage system.
Enhanced Thermal Management
Acting as a thermal interface, the elastic layer improves heat exchange between the electrochemical storage and the external environment.
By facilitating efficient heat dissipation, it helps maintain uniform cell temperature, reduces hotspot formation, and ultimately extends service life.
Mechanical Damping and Vibration Resistance
The elastic layer also functions as a mechanical buffer, absorbing shocks and vibrations during transport and operation.
This reduces risks of micro-cracks, delamination, or loose contacts within the module.
Summary
In summary, the elastic layer provides electrical insulation, structural resilience, thermal optimization, and mechanical protection. By integrating these functions, it significantly improves the safety, reliability, and durability of modern energy storage systems.
