钠离子电池负极用多酸基复合材料的制备
Preparation of polyoxometalate-based composite for the anode of sodium-ion battery
摘要
Abstract
Na+has a much larger ionic radius than Li+,which limits its insertion/extraction in the graphite-based anode materials commonly used in Li-ion battery.Polyoxometalate(POM)is coated by polypyrrole(PPy)with good conductivity,and directly combined with graphene oxide(GO)to form the anode materials for sodium-ion battery by one-pot method.GO is changed to reduced graphene oxide(RGO)for the reason of the high reducibility of POM.Benefiting from the multi-electron absorption properties of POM and the good electronic conductivity of PPy and RGO,the synthesized phosphomolybdic acid(PMo12)-PPy/RGO nanocomposite is used as the anode material of sodium-ion battery,the specific capacity can be stabilized at 300 mAh/g when charged and discharged with a current of 50 mA/g in 0.01-2.00 V.关键词
