摘要
金属硫化物有望在钠离子电池(SIB)中发挥巨大的实用潜力,这主要归功于其天然丰富、价格低廉和理论容量高的优点。然而,由于钠化/去二氮化反应产生的低导电性和巨大的体积变化,通常会导致钠离子电池的速率和循环性能无法令人满意。在这项工作中,我们合理地设计了一种共沉淀加硫化的方法,制备了由 N、S-掺杂碳(ZSS@NCS)包裹的三相异质结构空心 Zn-Sn-S 纳米盒,作为 SIB 的阳极。由 ZnS、SnS2 和 Sn2S3 组成的三相 ZSS 异质结构的共存有效地促进了 Na + 的快速扩散。由多巴胺衍生出的 N、S-掺杂碳(NSC)被涂覆在 ZSS 异质结构之外,这使得 ZSS 和 NSC 之间具有无限的亲和力,从而有效地加速了电子传输,并通过约束效应保持了结构的稳定性。异质结构 ZSS 和 NSC 的协同效应使 ZSS@NSC 阳极具有良好的钠存储特性,包括出色的放电容量(0.1 A g-1 时为 683.8 mAh g-1)、满足率(10.0 A g-1 时为 232.6 mAh g-1)和循环特性(150 次循环为 402.2 mAh g-1)。
Triphasic heterostructured Zn–Sn–S hollow nanoboxes encapsulated by N, S-codoped carbon as anodes for high-performance sodium-ion batteries
Metal sulfides have been expected huge practical potential for sodium-ion batteries (SIBs), which are mainly owing to their admirable merits of natural abundance, low price, and high theoretical capacity. However, the inferior electrical conductivity and enormous volume variation originating from sodiation/desodiaziton reactions usually result in unsatisfied rate and cycling properties. In this work, a coprecipitation with a following sulfurization method has been rationally designed to prepare the triphasic heterostructured hollow Zn–Sn–S nanoboxes encapsulated by N, S-codoped carbon (ZSS@NCS) as anodes for SIBs. The coexistence of triphasic ZSS heterostructures that consist of ZnS, SnS2, and Sn2S3 effectively facilitates the fast Na + diffusion. The N, S-codoped carbon (NSC) derived from the polydopamine is coated outside of the ZSS heterostructures, which provides infinite affinity between ZSS and NSC that efficiently accelerates the electron transport and maintains the structural stability via the confinement effect. The synergistic effects of the heterostructured ZSS and NSC endow the ZSS@NSC anode with favorable sodium storage properties including decent discharge capacity (683.8 mAh g−1 at 0.1 A g−1), satisfying rate (232.6 mAh g−1 at 10.0 A g−1) and cycling properties (402.2 mAh g−1 over 150 cycles).
