水系钠离子电池（ASIBs）因其较高的安全性而在水系电池领域备受关注。然而，水基电解液的特性降低了负极材料工作电位以及电化学稳定性，进而阻碍了水系钠离子电池的大规模应用。钛酸亚磷酸盐（NaTi2(PO4)3，NTP）因其出色的电化学性能和可调的结构，被认为是最具实用化前景的用于ASIBs的负极极材料之一。近年来，围绕NTP的研究取得了显著进展，但关于其研究现状和未来发展方向的综述仍然缺乏。在此背景下，本文首先介绍了NTP的基本特性，并深入分析了其实际应用所面临的挑战。随后，全面概述了提升NTP电化学性能的改性策略。最后，基于当前的研究状况和实际需求，提出了推动实现ASIBs实际应用的建议和展望。本综述旨在为未来研究提供方向指引，推动从基础材料创新逐步过渡到工业应用，进而加速水系钠离子电池的大规模商业化进程。
Aqueous sodium-ion batteries (ASIBs) have attracted great attention in aqueous batteries due to their merit of high safety. However, the constrained work potential and insufficient chemical stability of anode materials in aqueous electrolytes hinder the large-scale application of ASIBs. NaTi2(PO4)3 (NTP) is considered one of the most promising anode materials for ASIBs due to their excellent electrochemical performance and tunable structure. Recently, great achievements have been made in the development of NTP, however, a comprehensive review of existing studies is still lacking. In this context, this work first introduces the basic properties of NTP and analyzes the existing challenges. Subsequently, this review provides a comprehensive overview of the key strategies related to the design and modification of NTP materials with optimized electrochemical performance. Finally, based on the current research status and practical needs, suggestions, and future perspectives for advancing NTP in practical applications of ASIBs are presented. This review aims to guide the future research trajectory from basic material innovation to industrial applications, thus promoting the large-scale commercialization of aqueous sodium-ion batteries.
