层状氢氧化物 [Ni4Al(OH)10]NO3 的粒径对其电化学性质的影响
首发时间:2006-05-16
摘要:本文研究了晶粒大小不同的层状氢氧化物的电化学性能,发现晶粒的尺寸对大电流密度充放电行为有显著的影响:粒径较大的样品在较低的电流密度下充放电时,具有较大的放电容量;但随着电流密度增大时,容量下降得较快;粒径较小的样品,尽管电流密度较小时容量可能略低,但大电流密度放电(4.0 A.g-1)时,容量得到较好的保持。

The Effects of Particle Size of a Layered Double Hydroxide, [Ni4Al(OH)10]NO3 on its electrochemical performances
Abstract:In this paper the electrochemical performances of a layered double hydroxide, [Ni4Al(OH)10]NO3 of different particle sizes are reported. The results shows that the particle size of the sample has evident effect on its discharge capacity at high current densities: sample of bigger particle size may have a larger capacity when they are discharged at lower current density; but their capacity decreased quickly when the current density is increased; however, the capacity of samples of smaller particle size remains high even at very high current density, e.g. 4.0 A.g-1.
Keywords: layered double hydroxide (LDH) [Ni4Al(OH)10]NO3, particle size current density discharge capacity
