这是首次将混合过渡金属氧化物用于钠离子电池的负极。以草酸盐为前驱体，在320 ℃下热分解制备了NiCo 2 O 4尖晶石。这种材料与钠的电化学反应导致过渡金属的完全还原和Na 2 O的形成。这种新电极材料具有良好的可逆容量。300 mA h g（-1），钠离子电池与NaxCoO 2。
This is the first time that a mixed transition metal oxide is used for the negative electrode of a sodium-ion battery. The NiCo2O4 spinel was prepared by thermal decomposition of oxalate precursors at 320 degreesC. The electrochemical reactions of this material with sodium lead to the complete reduction of the transition metals and the formation of Na2O. The new electrode material shows reversible capacities of ca. 300 mA h g(-1) in sodium-ion cells versus NaxCoO2.
