Crosslinked copolymers with single Li

-ionic conductivity were prepared from oligo （oxyethylene） methacrylate （MEO

methacryloyl alkylsulfonic acid lithium （SAMLi）

and oligo （oxyethylene） dimethacrylate （DMEO

）. Li

-ionic conductivity of the copolymer is improved by crosslinking and presented as a function of polymerization degree （n） in MEO

comonomeric salt concentration （O/Li）

and crosslinking degree. The crosslinked copolymer P (0.7 MEO
