摘　　要：Fe_(x)VO_(4)型铁钒氧化物由于其高理论比容量、电压平台高、环境友好、成本低等优点,有望成为取代石墨的储能材料之一。然而,Fe_(x)VO_(4)的本征电导率较低以及体积膨胀导致的循环稳定性较差,阻碍了其实际应用的推广。本文对近年来Fe_(x)VO_(4)负极材料的研究进行了总结。基于Fe_(x)VO_(4)材料的晶体结构和离子迁移机制,介绍了其充放电机理。重点介绍了提高Fe_(x)VO_(4)电极材料电化学性能的改性研究策略,主要分为成分改性、形貌调控改性两个大类,包括离子掺杂、碳材料改性、材料纳米化等。最后对Fe_(x)VO_(4)未来发展的挑战和前景进行了展望,并对材料今后的研究重点提出可行性建议。Due to their high theoretical specific capacity,high voltage plateau,environmental friendliness,and low cost,Fe_(x)VO_(4)-type ferrovanadium oxides have become one of the energy storage materials that are expected to replace graphite.However,the low intrinsic conductivity of Fe_(x)VO_(4)and the poor cycling stability due to volume expansion hinder the promotion of its practical application.This paper summarizes the research on Fe_(x)VO_(4)anode materials in recent years.Based on the crystal structure and ion migration mechanism of Fe_(x)VO_(4)material,its charging and discharging mechanism is introduced.It focuses on the modification research strategy to improve the electrochemical performance of Fe_(x)VO_(4)electrode materials,which is divided into two major categories of composition modification and morphology modification according to the different modification mechanisms of the materials,including ion doping,carbon material modification,and material nanosizing.Finally,the challenges and prospects for the future development of Fe_(x)VO_(4)are envisioned,and feasible suggestions are made for the future research focus of the material.
