PAEK METHOD OF FORMING A SEPARATOR BASED ON PAEK FOR LITHIUM-ION BATTERY APPLICATION

摘要

The method for preparing a separator for a lithium ion battery according to the present invention comprises polymerizing a polymer having a hydroxy group at one end of a polyarylene ether ketone (PAEK) and a lactide, Preparing a PAEK-PLA copolymer by copolymerizing a PAEK-PLA copolymer and a polylactic acid (PLA); forming the PAEK-PLA copolymer to form a PAEK-PLA copolymer membrane; Forming a porous PAEK separator comprising pores formed by selectively removing the polylactic acid (PLA) domain in the copolymer membrane.
