摘要
首次报道通过一种聚苯乙烯磺酸钠(PSS)和三嵌段共聚物(P123)辅助的水热法,以Ni(NO3)2为原料,合成了新颖的绒球状β-氢氧化镍微米球(P1),其结构和形貌经X-射线衍射、扫描电镜和透射电镜表征。电化学测试结果表明:P1具有良好的电化学性质,在1 A·g-1电流密度下,电容量达1 214 F·g-1,经过1 000次循环后其容量可保持90%以上。
The novel self-assembled pompon-like β-Ni (OH) 2 microspheres ( p1 ) was synthesized for the first time, by the hydrothermal reaction of Ni (NO3 )2 with the assistance of sodium poly(4-styrene- sulfonate) (PSS) and triblock copolymer Pluronic ( P123 ) as the morphological controling suffactants. The structures and morphology were characterized by XRD, SEM and TEM. The electrochemical prop-erties of p1 were studied. The results showed that P1 exhibited excellent capacitance behavior with cou- lombic efficiency of 1 214 F·g^-1 at a charge/discharge current density of 1 A·g^-1 and an almost 90% coulombic efficiency after 1 000 cycles.
