PI battery separator is a key component of lithium-ion batteries made of polyimide (PI) as the core material. Its core functions include: Physical isolation: physically separate the positive and negative electrodes of the battery to prevent short circuits. Ion transport: allows lithium ions to pass freely during the charging and discharging process to ensure the normal operation of the battery. Safety assurance: through high temperature resistance, flame retardancy and other characteristics, improve the thermal stability of the battery and reduce the risk of thermal runaway. Performance optimization: high porosity and polar group design improve electrolyte wettability and ionic conductivity, and support high-rate charging and discharging.
