About this item

  • High Temperature Resistance & Safety: PI membrane exhibits exceptional thermal stability with a decomposition temperature up to 530°C (no melting point); under extreme conditions such as nail penetration or impact, the separator helps batteries remain non-combustible and non-explosive, providing superior safety compared to conventional polymer separators
  • Electrospun 3D Microporous Structure: produced via advanced electrospinning technology with a 3D interconnected microporous structure, tunable pore architecture, and ultra-high porosity of > 90%, providing rigid support for solid-state electrolyte filling while maintaining efficient ionic transport pathways
  • Solid-State Battery Compatibility: designed for all-solid-state batteries with high-voltage resistance and low interfacial impedance; suppresses dendrite penetration in lithium-metal batteries, inhibits polysulfide shuttling in lithium-sulfur batteries, and supports extended cycle life in sodium-ion batteries
  • High Porosity & Electrolyte Uptake: features ultra-high porosity of > 90%, liquid absorption rate of > 80%, and a lightweight areal density of only 3±0.5 g/m², minimizing added mass while ensuring excellent electrolyte impregnation and ionic conductivity
  • Wide Operating Temperature Range: operates across an ultra-wide temperature range of -160°C to 350°C, making it suitable for battery research under extreme temperature conditions and for high-temperature or cryogenic applications
