摘要
NASICON型Na_(2)FePO_(4)F因其Na+扩散通道畅通,结构稳定性好而被认为是理想的钠离子电池正极材料。但是其电子导电率和离子扩散系数低,导致电化学反应极化大,限制了该材料的实际应用。表面包覆改性是提升储能电极材料电导率的有效措施。综述了表面包覆的Na_(2)FePO_(4)F在钠离子电池中的应用研究进展。
The NASICON type Na_(2)FePO_(4)F is considered to be the ideal cathode material for sodium ion battery because of the unblocked diffusion channels of Na+and good structural stability.However,its low electronic conductivity and ionic diffusion coefficient,limit the practical application attributed to the big electrochemical polarization.The surface coating modification is an effective measure to improve the conductivity of electrode materials.The surface coated Na_(2)FePO_(4)F in the application of the sodium ion battery is reviewed.
