Abstract

Sodium-ion batteries (SIBs) have received increasing attention due to their low cost, high safety, and excellent electrochemical performance. Developing high-performance and low-cost cathode materials is the key to realizing the commercial application of SIBs. Among many cathode materials, Co-free Na_1-δNi_xFe_yMn_zO₂ cathode materials (NFMCMs) are one of the most promising materials, exhibiting potential for commercial applications because of their high capacity, low cost, and environmental friendliness. However, NFMCMs still face serious challenges such as complex phase transitions, poor air and thermal stability, significantly inhibiting their processability and potential application. This review presents the research progress of NFMCMs for the first time, clarifying their crystal structure, charging and discharging mechanism, degradation mechanism and modification strategies. Furthermore, the existing prospects and future directions of NFMCMs are analyzed and projected. This work aims to guide the development of high-performance NFMCMs for high-energy-density and long-cycle-life SIBs.

高能量密度长循环寿命钠离子电池负极Na1-δNixFeyMnzO2的研究进展与展望

钠离子电池因其低成本、高安全性和优异的电化学性能而受到越来越多的关注。开发高性能、低成本的阴极材料是实现sib商业化应用的关键。在众多正极材料中，无co的Na1-δNixFeyMnzO2正极材料（nfmcm）因其高容量、低成本和环保的特点而成为最有前途的材料之一。然而，nfmcm仍然面临着严峻的挑战，例如复杂的相变，差的空气和热稳定性，严重抑制了其可加工性和潜在的应用。本文首次综述了nfmcm的研究进展，阐明了其晶体结构、充放电机理、降解机理和改性策略。最后，对nfmcm的现状和未来发展方向进行了分析和预测。这项工作旨在指导用于高能量密度和长循环寿命sib的高性能nfmcm的开发。
