With the continuous iteration of safety standards in the energy storage industry,protection systems such as cell thermal runaway prevention,cabin fire suppression,and structural heat insulation have become increasingly sophisticated.Nevertheless,reviews of numerous power station safety accidents indicate that the large-scale spread of fires in energy storage systems rarely stems solely from single-cell ignition.Instead,it is primarily caused by high-temperature arcing and failure of high-voltage copper bars and wiring connectors,which form fire propagation channels across modules and circuits.As a vulnerable link in PACK protection,the upgraded fire-resistant insulation of exposed high-voltage components has become a core focus of industry safety optimization.As a high-performance ceramic protective material,ANDI fire-resistant self-adhesive tape has become a key supporting material for refined high-voltage protection in energy storage systems,thanks to its reliable technical performance and excellent mass production adaptability.

 

　　Different from ordinary insulating and flame-retardant tapes,ANDI fire-resistant self-adhesive tape is made of ceramic silicone rubber composite substrate with pre-coated pressure-sensitive adhesive.It features superior flexibility and requires no additional glue application,enabling direct winding and fitting for irregular-shaped components with strong adaptability.Under normal operating conditions,it provides stable electrical insulation.When exposed to open flame or high-temperature heat,the material rapidly ceramicizes to form a hard and dense protective layer.It achieves zero dripping,non-combustible support and effective flame spread blocking,efficiently preventing short circuits and arc re-ignition of conductive parts under high temperatures and restraining fire expansion from the source.

 

　　All performance indicators of the product are verified by authoritative tests,fully adapting to harsh energy storage operating conditions.It reaches FV-0 flame retardant grade to eliminate secondary ignition risks caused by molten droplets,and can withstand flame impact at temperatures up to 1000℃with stable structural performance in extreme fire scenarios.It delivers outstanding electrical performance,with high-temperature insulation resistance exceeding 500MΩand breakdown voltage above 5KV,maintaining a reliable insulating barrier in high-temperature environments.Adapted to the complex operating conditions of outdoor energy storage facilities including temperature cycling,high humidity and continuous vibration,the product has passed 1200-hour double 85 damp-heat aging test,ensuring no degumming,cracking or obvious performance attenuation during long-term service and matching the long-life operation requirements of energy storage equipment.In addition,it is compatible with various high-speed wrapping machines to support automatic continuous wrapping,significantly improving the assembly efficiency and product consistency of PACK production lines and adapting to large-scale industry production.

 

　　In practical energy storage applications,the material targets core risk points precisely.Firstly,it is applied to high-voltage copper bar protection for PACKs,focusing on wrapping vulnerable positions such as bending parts and bolt lap joints of module connecting copper bars to prevent insulation damage and short circuits,and block cross-module fire propagation caused by cell thermal runaway.Secondly,it strengthens the protection of high-voltage wire harnesses at joints,wire outlet holes and bending sections inside energy storage cabinets,solving the problem of high-temperature melting,failure and combustion of ordinary tapes.Thirdly,it is universally applicable to new energy power battery packs and vehicle high-voltage protection scenarios,realizing material sharing between power energy storage and vehicle-mounted energy storage to reduce enterprise supply chain costs.

 

　　Compared with traditional mica tapes and rigid heat insulation sheets,the fire-resistant self-adhesive tape has prominent advantages.Mica tapes are prone to delamination after bending and rapid insulation attenuation in humid environments,while rigid heat insulation sheets feature poor fitting performance and cannot adapt to irregular structures or automated production.In contrast,ANDI’s tape integrates flexible fitting,long-term weather resistance,fire-resistant insulation and high production efficiency,with far superior overall adaptability to traditional materials.

 

　　In terms of industry trends,energy storage safety design has shifted from cell and fire suppression orientation to full-process and refined protection.Fire-resistant insulation for high-voltage connectors has evolved from an optional configuration to a mandatory industry standard.With the continuous upgrade of energy storage system voltage and capacity,as well as the popularization of integrated CTP and module-free PACK structures,the demand for thin,highly flexible,weather-resistant and multi-functional fire-resistant self-adhesive tapes will keep growing.Industry testing standards will also be upgraded from single flame retardant tests to composite condition tests covering aging,vibration and high-temperature combustion.

 

　　Currently,product quality varies greatly in the market.Low-cost products usually suffer from fragile ceramic layers and insulation failure under high temperatures,failing to cope with extreme thermal runaway conditions.Enterprises should select products based on core indicators including high-temperature fire resistance,insulation performance and aging resistance,and verify product reliability through practical working condition tests.

 

　　In conclusion,although fire-resistant self-adhesive tapes cannot completely prevent cell thermal runaway,they can effectively block fire spread and avoid secondary safety accidents,serving as a key material to improve the safety redundancy of energy storage systems.Amid the high-quality and safety-oriented development of the energy storage industry,high-performance ANDI fire-resistant self-adhesive tapes will be further applied in full energy storage scenarios and become a standard core material for the safety system of energy storage PACKs.
