Abstract
Single-ion conducting polymer electrolytes (SICPEs) have received much attention due to their excellent Li+ transference numbers, which can effectively reduce the concentration gradient and inhibit the growth of lithium dendrites. Recently, sulfonimide based SICPEs with superior ionic conductivity have become the most widely studied SICPEs by virtue of their highly delocalized anions and diverse molecular designability. In this review, the molecular design of sulfonimide based SICPEs is summarized in terms of anionic groups and polymer backbones of SICPEs. Then, the potential influence of SICPEs on battery safety is discussed from electrolyte level and interface level, respectively. It is believed that the battery safety and interface compatibility need to be given sufficient attention for SICPEs, in addition to the ion conductivity and Li+ transference number. It is hoped that this review can inspire a deeper consideration on SICPEs, which can pave a new pathway for the high-safety and high-energy-density lithium batteries.
期刊介绍:
eTransportation is a scholarly journal that aims to advance knowledge in the field of electric transportation. It focuses on all modes of transportation that utilize electricity as their primary source of energy, including electric vehicles, trains, ships, and aircraft. The journal covers all stages of research, development, and testing of new technologies, systems, and devices related to electrical transportation.
The journal welcomes the use of simulation and analysis tools at the system, transport, or device level. Its primary emphasis is on the study of the electrical and electronic aspects of transportation systems. However, it also considers research on mechanical parts or subsystems of vehicles if there is a clear interaction with electrical or electronic equipment.
Please note that this journal excludes other aspects such as sociological, political, regulatory, or environmental factors from its scope.
