“…However, these types of materials (such as Sn, W, Bi, Se, etc.) experience extreme volume expansion during the sodiation and desodiation processes. − To mitigate this issue, Zhang et al introduced a groundbreaking anode, P-doped carbon layers (Cu 3 P@PC). The deliberately crafted Cu 3 P@PC architecture enhances Na + diffusion kinetics and mitigates volume variation effects.…”

In recent years, sodium ion batteries (SIBs) emerged as promising alternative candidates for lithium ion batteries (LIBs) due to the high abundance and low cost of sodium resources. However, their commercialization has been hindered by inherent limitations, such as low energy density and poor cycling stability. To address these issues, doping methodology is one of the most promising approaches to boosting the structural and electrochemical properties of SIB electrodes. This review provides a comprehensive overview of recent advancements in doping strategies, focusing on the improvement of the performance of SIBs. Various dopants including s-and p-block elements, transition metals, oxides, carbonaceous materials, and many more dopants are discussed in terms of their effects on enhancing the electrochemical properties of SIBs. Furthermore, the mechanisms responsible for the improvement in the performance of doped SIBs materials are also discussed. It also highlights the importance of doping sites in the crystal lattice, which also play a crucial role in doping in optimizing electrode structure, enhancing ion diffusion kinetics, and stabilizing electrode/electrolyte interfaces. The review ends by looking at the recent studies in simultaneous multiple heteroatom doping, offering valuable perspectives for a high performance SIB. This study provides valuable insight into the researchers and battery industries striving for advancements in energy storage technologies.

Metal thiophosphite has demonstrated promising application potential as an anode material for sodium‐ion batteries. Nevertheless, the intrinsic low electrical conductivity and drastic volume expansion impede its commercialization. Herein, a series of metal thiophosphite/Ti3C2Tx (metal = Fe, Ni, Co, and Cd) composites are constructed via Lewis acidic molten salt etching followed by synchronous phospho‐sulfurization. The Ti3C2Tx substrate endows the thiophosphite/Ti3C2Tx hybrids with high electrical conductivity. Importantly, thiophosphite grown on the MXene layers exhibits a 3D cross‐linked structure, which not only facilitates electron/ion transport, but also maintains robust structural stability owing to the space confinement effect. As a proof of concept, FePS3/Ti3C2Tx demonstrates remarkable rate performance (827.4 and 598.1 mAh g−1 at 0.1 and 10 A g−1, respectively) along with long‐term cycling stability (capacity retention of 93.7% after 2000 cycles at 5 A g−1). Impressively, the FePS3/Ti3C2Tx//NVPO full cell exhibits a high reversible capacity of 396.8 mAh g−1 over 1350 cycles at 2 A g−1. The sodium storage mechanism of FePS3/Ti3C2Tx anode is further unveiled through in situ XRD/ex situ HRTEM characterizations and theoretical calculations. This work provides a fresh perspective on enhancing the electrochemical performance of thiophosphite through the in situ construction of thiophosphite/Ti3C2Tx hybrids.

Bismuth (Bi) has attracted widespread attention for sodium storage due to its high electronic/ionic conductivity, suitable reaction potential, and theoretical capacity (386 mAh g−1). However, Bi electrodes have a relatively high volumetric expansion ratio, which constrains their high capacity and affects the battery's cycle performance. Herein, a highly dispersed Bi atomic cluster is controllably prepared anchored on a porous TiO2 substrate through in situ segregation from Bi4Ti3O12 (TiO2/BiAC). The highly dispersed Bi clusters can serve as an “Ionic sponge” and accommodate more Na+ without causing excessive stress. Additionally, it aids in the decomposition of NaPF6, leading to the formation of a durable solid‐electrolyte interphase (SEI) layer rich in inorganic components. As expected, TiO2/BiAC exhibits excellent sodium storage performance in terms of cycling stability (346 mAh g−1 after 1000 cycles@ 1A g−1) and rate capability (231 mAh g−1 @ 100 A g−1). The pouch cell is further assembled and exhibits a specific capacity of 1.2 Ah after 200 cycles. This discovery presents a new method for developing efficient anode materials and is essential for steering the advancement of anode materials with fast charge–discharge capabilities.
