蜂窝层状氧化物从Na 2Ni 2-xCoxTeO 6家庭进行了评估，作为正极在可充电钠电池在环境温度和升高的温度下使用离子液体。用钴取代镍将放电电压增加到接近4V（相对于Na+/Na），超过大多数Na基层状氧化物正极的平均电压。
Honeycomb layered oxides from Na2Ni2-xCoxTeO6 family were assessed for use as positive electrodes in rechargeable sodium batteries at ambient and elevated temperatures using ionic liquids. Substitution of nickel with cobalt increases the discharge voltage to nearly 4 V (versus Na+/Na), surpassing the average voltages of most Na based layered oxide positive electrodes.
