Silicone potting compound | Battery cell fixing and potting solution – enhancing battery safety and lifespan

In power batteries, energy storage batteries, and various lithium battery modules, the issue of cell fixation and potting is no longer a matter of “whether there is any”, but rather a matter of choosing what material to use and how to choose it.The appropriate potting material not only determines the structural reliability, but also directly affects the safety, stability, and service life of the battery system. 🔋 Vibration and Shock: Mechanical Stress during Transportation, Running, and Start-Stop Processes 🔥 Thermal Cycling Stress: Repeated Temperature Rise and Drop during Charging and Discharging ⚡ Electrical Safety Risks: Extremely High Insulation Performance Requirements in High-Voltage Environments 🌧️ Environmental Erosion: Long-term Effects of Moisture, Dust, and Condensate Water If the battery cells lack effective fixation and protection, they are prone to: Loose structure, fatigue of solder joints, decreased insulation performance, potential short-circuit hazards, noise and resonance issues, and significantly shortened service life👉 The core value of cell fixation and potting lies in providing long-term stable “second-layer protection” for cells in terms of structure, electrical, and environmental aspects. II. Key requirements for adhesive used in cell fixation and potting For cell application scenarios, potting materials typically need to meet the following requirements simultaneously: – Good fluidity and filling performance fully coat the cells and gaps, avoiding voids – Moderate flexibility to buffer vibrations and accommodate thermal expansion and contraction, avoiding stress concentration – Excellent electrical insulation performance enhances the overall electrical safety level of the package – The flame retardant and temperature resistance capabilities meet the long-term reliable operation requirements of the battery system – Lightweight and noise reduction: Reduce the weight of the system while lowering the operating noise III.
