New national standard safeguards battery safety-Andi fire-resistant insulation buffer pad makes thermal runaway'detour'

  With the rapid development of new energy vehicles and energy storage industry,the safety of power batteries has become a focus of attention for the whole society.The mandatory national standard"Safety Requirements for Power Batteries for Electric Vehicles"(GB38031-2025)recently released by the country will be implemented from July 1,2026,setting a safety red line for the industry with stricter requirements for flame retardancy,fire resistance,and thermal management.In this context,fire-resistant insulation buffer pads,as the core protective material of battery packs,are becoming an important technical support for the implementation of the new national standard with their technological breakthroughs and performance advantages,promoting battery safety into a new stage.
 
  The new national standard has put forward almost strict requirements for the flame retardant performance of battery systems,and the FV-0 flame retardant level of Andi's fire-resistant insulation buffer pad means that it can self extinguish within 0.3 seconds after the evacuation of the open flame,and there is no risk of droplet ignition.This feature can effectively block the flame propagation path when the battery generates local open flames due to thermal runaway,and strive for a critical time window for emergency response.What is more noteworthy is that Andi's fire-resistant insulation cushion can still maintain structural integrity at a high temperature of 1000℃.Its design with an insulation rate of up to 50%can delay energy transfer in high-temperature areas by more than 50%,greatly reducing the possibility of adjacent cells being"chain ignited".
 
  In terms of mechanical protection,the new national standard has strengthened the ability standards for battery systems to resist compression and deformation.Andi's fire-resistant insulation cushion is designed with precision mechanics that allows for a compression stress of≥7%at 0.6MPa and a compression capacity of≤13%at 1.0MPa.It can absorb impact energy through elastic deformation during vehicle collisions and avoid uneven stress on the battery cells caused by excessive compression.This"combination of rigidity and flexibility"characteristic enables the battery module to maintain structural stability even under extreme working conditions,building a solid safety defense line from a physical perspective.
 
  In the face of differentiated application scenarios between new energy vehicles and energy storage systems,Andi's customized die-cutting capability for fire-resistant and heat-insulating cushion pads demonstrates unique advantages.Whether it is the arrangement and combination of square,soft pack or cylindrical battery cells,three-dimensional adaptation can be achieved through precise drilling,layered composite and other processes,ensuring equal protection for each battery cell unit while maximizing space utilization.This flexible manufacturing capability perfectly aligns with the"system level safety design"concept emphasized in the new national standard,helping battery companies build a comprehensive protection system from individual units to systems.
 
  Currently,as the new national standard enters the mandatory implementation stage,the fire-resistant insulation buffer pad has been upgraded from an"optional item"to a"mandatory item".In the actual application of an energy storage power station in Zhejiang,the battery pack using this material successfully extended the thermal diffusion time to more than twice the national standard requirement in the thermal runaway test;According to collision test data from a certain new energy vehicle company,the installation of a buffer pad reduced the deformation of the battery pack structure by 37%,and the probability of triggering thermal runaway decreased by 62%.These empirical data confirm the technological synergy effect between new materials and new national standards.
 
  From an industry perspective,the technological evolution trajectory of fire-resistant and heat-insulating buffer pads is a microcosm of the upgrading of China's battery safety standards.As the industry bids farewell to the extensive development stage of"energy density only theory",safety technology innovation guided by the new national standard is redefining the value coordinate system of power batteries.This material,which combines"hardcore performance"and"scenario intelligence",not only provides compliant solutions for car manufacturers and energy storage companies,but also heralds the acceleration of a new era of battery safety shifting from passive defense to active prevention and control.
