Novel polynaphthalimide, electrode comprising the same and lithium-ion battery comprising the same

Abstract

Disclosed is a novel polynaphthalimide which comprises a repeat unit represented by the following formula (I) wherein naphthalimide is bonded to substructure A, wherein A is a cyano-substituted arylamine moiety. The polynaphthalimide polymer provides an electrode material disposed on an electrode collector, wherein the electrode may be a cathode or an anode, said electrode comprising the disposed polynaphthalimide is utilized in a lithium-ion battery, providing an efficient storage capability of the newly designed triphenylamine-based polynaphthalimides (TPA-PNIs) and exhibiting outstanding electrochemical performance and operation durability.
