摘要

The behavior of polymer electrolytes in lithium batteries is reviewed in the context of molecular scale models as well as on the system scale. It is shown how the molecular structure of the electrolyte strongly influences ion transport through the polymer as well as across the interfaces And determines the values of a number of parameters needed for system model that can predict the performance of the battery(e.g.k, D, t~+_0 And i_0). The interaction of the electrolyte with the electrodes not only leads to transfer of the lithium ion across the interface but also to side Reactions that profoundly influence the calendar and life cycle of the battery.
