As consumers demand higher range for electric vehicles and the energy density of lithium-ion batteries continues to improve, materials with higher energy density may have lower thermal stability, leading to frequent safety incidents involving thermal runaway in power batteries. Currently, new energy vehicle manufacturers mainly adopt two methods: active and passive protection to prevent the spread of thermal runaway in power batteries. Passive protection primarily involves physically isolating battery cells, battery modules, and battery packs using various flame-retardant and insulating materials. Common types include mica materials, aerogels, flame-retardant foam, ceramicized silicone rubber, etc.
Globally, the demand for battery system safety protection markets has exploded, coupled with the increasing requirements for thermal performance parameters of new energy vehicles under relevant regulations. Companies have begun to accelerate material design to control thermal runaway in batteries and block the chain reaction of runaway between cells. China is a major participant in the global new energy passenger vehicle market, so the Chinese battery system safety protection market also occupies an important position in the global market. For this reason, based on research into this market, Frost & Sullivan (Frost & Sullivan) has released an independent research report titled 'Global and China Battery System Safety Protection Industry Overview 2025'.
