水系钠离子电池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水系钠离子电池的负极极材料之一。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,提出了推动实现水系钠离子电池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。
