Aerogel Sheet
LFJ's aerogel sheet is the ultimate thermal runaway barrier for EV battery packs. With an ultra-thin profile ideal for CTP and LFP architectures, it offers top-tier fire resistance and compressibility to block thermal propagation and safely absorb cell swelling.
Product Overview
In the rapidly advancing EV market, especially with high-density CTP (Cell-to-Pack) and LFP battery architectures, space is at an absolute premium, and safety is non-negotiable. LFJ’s Aerogel Sheets are engineered as the ultimate thermal propagation barrier. Placed directly between battery cells, these ultra-thin sheets provide extreme thermal insulation to prevent a single failing cell from triggering a catastrophic pack-wide thermal runaway. Furthermore, our aerogel sheets are designed with excellent compression and rebound properties, absorbing the natural swelling stress of lithium-ion cells during charge/discharge cycles without losing their thermal resistance.

FAQ
1. How does an Aerogel Sheet stop thermal propagation in a battery pack?
If a lithium-ion cell experiences a short circuit and goes into thermal runaway, its temperature can spike to over 600°C in seconds. LFJ's Aerogel Sheet acts as a severe thermal bottleneck. Because of its ultra-low thermal conductivity, it blocks that extreme heat from instantly transferring to the adjacent cell, giving the vehicle's management system critical time to react and preventing the entire pack from catching fire.
2. Can these sheets cause dust issues on our automated battery assembly line?
No. For cleanroom EV battery assembly, we offer Encapsulated Aerogel Pads. By sealing the aerogel core inside specialized flame-retardant PET or PI films, we guarantee a 100% dust-free product that is safe for precision automated pick-and-place machinery and will not contaminate your battery modules.
