摘要
水系锌碘电池因其高理论比容量、高能量密度、优异的倍率性能、丰富且低廉的原料和高安全性等特点,而被认为是未来电能存储领域最具前景的候选储能器件之一。然而,多碘离子的穿梭效应严重影响其自放电性能、Coulombic效率和循环寿命,进而限制了其大规模应用。首先介绍了水系锌碘电池的结构、储能机理及其穿梭效应产生的原因,随后从正极、电解液和隔膜3个方面详细综述了水系锌碘电池穿梭效应的抑制策略,最后总结了当前水系锌碘电池存在的问题并提出了展望,以期为加快推进水系锌碘电池产业化提供借鉴。
Aqueous Zn iodine battery(AZIDB) is recognized as one of the most promising energy storage devices in the future electric power storage area due to its high theoretical specific capacity, superior energy density, good rate capability, abundant and low-cost of raw materials and high safety. However, the shuttle effect of polyiodide seriously increases the self-discharge current,decreases the Coulombic efficiency and shortens the cycle life of AZIDB, further limiting the large-scale application. In this review,the configuration of AZIDB, the corresponding energy storage mechanism and the reasons of shuttle effect were represented. The suppression strategies of shuttle effect in AZIDB from cathode, electrolyte and separator aspects were described. In addition, we summarized the current problems and shared thoughts on the future research development in AZIDBs to provide a reference for promoting the industrialization of AZIDBs.
