Abstract
A solid polymer electrolyte includes a crosslinking agent, a poly(alkylene glycol) alkyl ether alkyl (meth)acrylate, a lithium salt and a curing initiator. The crosslinking agent includes a compound represented by formula (I): whereinA is oxygen, COO, alkyl of C1-4, or a single bond,R is a 6-membered aliphatic, aromatic or heterocyclic group,Ra, Rb and Rc independently are a linear or branched alkyl group of C1-10,Rd, Re and Rf independently are H or a methyl group, andp, q and r independently are an integer of 1 from 20.The poly(alkylene glycol) alkyl ether alkyl (meth)acrylate is represented by formula (II) whereinR1 and R2 independently are a linear or branched aliphatic or aromatic group of C1-10,R3, X, Y, Z independently are H or a methyl group, andp, q and r independently are an integer from 1 to 20.
