Title:
PHASE-INVERSION POLYMER COMPOSITE MATERIAL, FABRICATING METHODS AND APPLICATIONS OF SAME
Document Type and Number:
WIPO Patent Application WO/2021/045850
Kind Code:
A3
Abstract:
A composite film usable as a separator of an electrochemical device includes hBN nanosheets and at least one polymer. The hBN nanosheets are uniformly dispersed within a matrix of said least one polymer to achieve a highly porous microstructure. Said at least one polymer comprises one or more electrically insulating and electrochemically inert polymers.
