Abstract：The safety of high-energy-density lithium-ion batteries is becoming increasingly important for the future development of electric vehicles.Metalized plastic current collectors(MPCCs),as inert active materials,are key components in simultaneously enhancing both high energy density and safety.In addition to designing new plastic film polymer substrates,optimizing fabrication techniques to improve conductivity,mechanical strength,and metal/plastic film interfacial adhesion,the development of functional polymer substrates is also a crucial direction for advancing high-performance MPCCs.This approach effectively reduces the risk of thermal runaway in lithium-ion batteries.This article emphasizes current methods for functionalizing polymer substrates,which include incorporating inorganic/organic flame retardants into the polymers;developing temperature-sensitive and thermally responsive MPCC materials by introducing a positive temperature coefficient effect;or enhancing the thermal stability of polymer substrates,thereby improving the safety performance of high-energy-density batteries.This paper provides a functionalization direction for the development of MPCC in order to promote its application in lithium-ion batteries.
