Cyclopropene cationic polymer as well as preparation method and application thereof

The invention belongs to the technical field of aqueous batteries, and particularly relates to a cyclopropene cationic polymer as well as a preparation method and application thereof. A cyclopropene cationic aromatic three-membered ring structure exists in the cyclopropene cationic polymer, and one of the cyclopropene cationic polymers is shown as a formula (I). The cyclopropene cationic polymer disclosed by the invention can be used as a positive electrode iodine carrier material of the water-based zinc-iodine battery, and the halogen bond action of halogen pair ions and iodine is enhanced through ion pair stress between cyclopropene cations and halogen pair ions thereof, so that the electrochemical performance of the water-based zinc-iodine battery is enhanced. # imgabs0 # 本发明属于水系电池技术领域，具体涉及一类环丙烯阳离子聚合物及其制备方法和应用。所述环丙烯阳离子聚合物中均存在环丙烯阳离子芳香三元环结构，其中的一种环丙烯阳离子聚合物如式(Ⅰ)所示。本发明所述环丙烯阳离子聚合物可以作为水系锌碘电池的正极碘载体材料，其通过环丙烯阳离子与其卤素对离子之间的离子对应力来增强卤素对离子与碘的卤键作用，从而增强水系锌碘电池的电化学性能。#imgabs0#
