Sodium-ion capacitors (SICs), designed to attain high energy density, rapid energy delivery, and long lifespan, have attracted much attention because of their comparable performance to lithium-ion capacitors (LICs), alongside abundant sodium resources. Conventional SIC design is based on battery-like anodes and capacitive cathodes, in which the battery-like anode materials involve various reactions, such as insertion, alloying, and conversion reactions, and the capacitive cathode materials usually depend on activated carbon (AC). However, researchers have attempted to construct SICs based on battery-like cathodes and capacitive anodes or a combination of both in recent years. In this Minireview, charge storage mechanisms and material design strategies for SICs are summarized, with a focus on the battery-like anode materials from both inorganic and organic sources. Additionally, the challenges in the fabrication of SICs and future research directions are discussed.
钠离子电容器(SIC)旨在实现高能量密度、快速能量传递和长寿命,由于其与锂离子电容器(LIC)具有可比的性能以及钠资源丰富,因此备受关注。传统的SIC设计基于类似电池的阳极和电容性阴极,其中类似电池的阳极材料涉及各种反应,如嵌入、合金化和转化反应,而电容性阴极材料通常依赖于活性炭(AC)。然而,近年来研究人员尝试构建基于类似电池的阴极和电容性阳极或两者结合的SIC。在这篇综述中,总结了SIC的电荷存储机制和材料设计策略,重点关注来自无机和有机来源的类似电池的阳极材料。此外,还讨论了SIC制造中的挑战和未来的研究方向。
