Manipulating 2D Few‐Layer Metal Sulfides as Anode Towards Enhanced Sodium‐Ion Batteries

Abstract

High‐quality anodes are very important for the future generations of rechargeable sodium‐ion batteries (SIBs). Metal sulfides (MSs) as a promising anode have attract tremendous attentions and shown impressive results in terms of versatile material species, low‐cost raw materials, and excellent electrochemical performance. In particular, the unique 2D few‐layer structure of MSs provides a new view for overcoming some challenges appeared on anodic electrodes, such as volume change, structure collapse, high‐rate capability, and confinement of phase‐variation of MSs. Here, we review some of the recent scientific advances in 2D MSs, including the synthetic strategies, electronic structure, and electro‐chemical performance on SIBs.

“…They also exhibit high electrical conductivity due to their weak Van der Walls interactions, diathermancy, and energy band structure. [ 92–98 ] In addition, WS 2 also provides high electrochemical stability. [ 99 ] These salient features make it a suitable candidate for Na + storage.…”

Manipulating metal–sulfur interactions for achieving high‐performance S cathodes for room temperature Li/Na–sulfur batteries

“…Effective hosts include carbonaceous materials (graphene, carbon nanotiles, carbon fibers), metal oxides, and metal sulfides, as well as metals. [35][36][37][38][39][40][41][42][43][44][45] Recently, there is a new synthesis and morphology control method that can help the future synthesis of sulfur hosts. 46 Although the utilization of various hosts can enhance the performance of Li/Na sulfur batteries, a giant leap is a prerequisite for meeting the practical targets for practical applications.…”

“…Considerable efforts have, therefore, been made to solve these problems to improve the performance of Li/Na sulfur batteries through the confinement of S or constructing chemical bonding between S and its host materials. Effective hosts include carbonaceous materials (graphene, carbon nanotiles, carbon fibers), metal oxides, and metal sulfides, as well as metals 35–45 . Recently, there is a new synthesis and morphology control method that can help the future synthesis of sulfur hosts 46 .…”

3D Carbon Networks: Design and Applications in Sodium Ion Batteries

“…To date, numerous kinds of materials have been proposed for SIBs electrodes. For anodes, it contains carbon‐based materials, [10a] metal compound materials (such as metal oxides, [1c] metal sulfides, [10b] metal selenides [10c] and metal phosphides [10d] ), and alloy materials, [13] etc., while cathodes are usually composed by polyanionic compounds, [14] transition‐metal oxides, [15] and organic compounds [16] . Among the aforementioned materials, extensive study on carbon has been carried out from the earliest stage.…”
