Recent Tactics and Advances in the Application of Metal Sulfides as High‐Performance Anode Materials for Rechargeable Sodium‐Ion Batteries

Abstract

The successful development of post‐lithium technologies depends on two key elements: performance and economy. Because sodium‐ion batteries (SIBs) can potentially satisfy both requirements, they are widely considered the most promising replacement for lithium‐ion batteries (LIBs) due to the similarity between the electrochemical processes and the abundance of sodium‐based resources. Among various SIB anode materials, metal sulfides are most extensively studied as materials for high‐performance electrodes due to the versatility of their synthesis procedure, utilization potential, and high sodiation capacity. Herein, some of the most effective strategies aimed at effectively alleviating the performance shortcomings of these materials from the materials engineering/design perspective are summarized. In terms of facilitating ion transport in SIBs, which represents one of the most critical aspects of their performance, a specific family of strategies related to a particular operational mechanism is considered rather than categorizing based‐on individual sulfide materials. In the foreseeable future, the development of highly functional SIBs electrode materials and utilization of metal sulfides will become highly relevant due to their stability and performance characteristics. Therefore, it is anticipated that this review will guide further research and facilitate the realization of various applications of sulfide‐based high‐performance rechargeable batteries.

Cubic Spinel XIn2S4 (X = Fe, Co, Mn): A New Type of Anode Material for Superfast and Ultrastable Na‐Ion Storage

“…Moreover, no characteristic peaks of Fe are observed at this stage mainly due to its small crystalline size or amorphous feature. [34,44,52,53] As sodiation from 0.6 to 0.01 V (state III), the peaks of Na y -In 6 S 7 gradually shift to the lower 2φ angle and come back to the higher angle during the subsequent desodiation process (from 0.01 to 1.2 V; state IV), demonstrating the reversible Na-ion (de)intercalation process. It is reported that the Na-ion (de)intercalation processes usually display the relatively low volume variation, which could significantly stabilize the conversion-based components during cycling.…”

The Multicomponent Synergistic Effect of Sandwich Structure Hierarchical Nanofibers for Enhanced Sodium Storage

“…The larger ion radius of Na + (1.02 Å) compared with Li + (0.76 Å) means the slow kinetics and lower energy density for SIBs. [6,7] Most electrode materials especially anodes suitable for LIBs usually exhibit terrible cycle capacities and rate properties for SIBs. [8,9] Therefore, it is very important to design anode materials with the high specific capacity and rapid diffusion kinetics.…”

In Situ Construction of Efficient Interface Layer with Lithiophilic Nanoseeds toward Dendrite‐Free and Low N/P Ratio Li Metal Batteries

“…Impressively, metal sulfides demonstrate promising application prospects in lithium batteries owing to its excellent electronic conductivity. [31][32][33] Li 2 S and Li-based alloy can be in situ formed when the metal sulfide reacts with lithium, which is also conducive to the homogeneous Li nucleation and growth. [34,35] Here, a robust lithiophilic carbonaceous scaffold enabled by nanosized Sb 2 S 3 is synthesized via a facile one-step hydrothermal synthesis.…”
