Ion-conducting block copolymers(BCPs) as conducting materials have attracted significant interests in solid state lithium batteries. BCP self-assembly offers promise for designing ordered materials with nanoscale domains. Such nanostructures provide a facile method for introducing sufficient mechanical stability into polymer electrolyte membranes, while maintaining the ionic conductivity at levels similar to corresponding solvent-free homopolymer electrolytes. This ability to simultaneously control conductivity and mechanical integrity provides opportunities for the fabrication of sturdy, yet easily processable, solid-state lithium batteries. This review presents a brief overview of recent progress in ion-conducting block copolymers base on polyoxyethylene and single ion conductors. We also summarize some experimental studies of BCP electrolytes with respect to the effects of morphology on ionic conductivity. Finally, we present some remaining challenges for BCP electrolytes and highlight several important areas for future research.
