Polymer electrolytes have attracted enormous attention toward a range of electrochemical devices including fuel cells and lithium batteries. In order to increase the ionic conductivity of polymer electrolyte, particularly at room temperature, many researchers have attempted to reduce the crystallinity of polymers by varying the molecular architectures of polymers and/or adding plasticizers. Unfortunately, the reduction in polymer crystallinity resulted in the loss of molecular arrangement of ion-binding sites, intimately related to the decrease in ion transport efficiency. In present study, we report a new mean of achieving high ionic conductivity in polymer electrolytes by designing crystal-in-amorphous polymer frameworks. Key to success stemmed from the from the selective confinement of zwitterions into nanoscale ionic channels of polymers through favorable dipolar interactions. |
