摘要
Abstract
With the increase of energy density,high-energy-density lithium-ion batteries face increasingly prominent safety issues,among which the thermal shrinkage and flammability of separators are regarded as critical factors triggering thermal runaway.Constructing flame-retardant coatings on polyolefin-based separa-tors to fabricate high-safety composite separators has been considered an effective approach that balances electrochemical performance and industrial feasibility.However,in existing studies,pronounced trade-offs remain among flame retardancy,electrochemical performance,and processability,and the underlying mech-anisms for their synergistic optimization have not yet been systematically summarized.This review systemati-cally summarizes recent research progress on three types of flame-retardant composite separators,including inorganic flame-retardant,organic flame-retardant and organic/inorganic synergistic flame-retardant systems.The composition design,flame-retardant mechanisms,and their effects on battery performance are ana-lyzed.Achieving the synergistic optimization of high flame retardancy and efficient ion transport remains a key challenge in current research.Furthermore,multifunctional integrated design and scalable fabrication strategies compatible with existing manufacturing processes are proposed as important development direc-tions for high-safety composite separators.关键词
