摘要/Abstract

摘要： 研究了Ni_xCo_1-_x(OH)₂干凝胶中钴含量对其电性能及循环稳定性的影响。用溶胶-凝胶法制备了Ni_xCo_1-_x(OH)₂干凝胶材料,用液氮吸附、XPS和XRD研究了含钴Ni(OH)₂干凝胶的组成和结构,用恒电流技术研究了它们的电容性能。结果表明,Ni_xCo_1-_x(OH)₂干凝胶具有较高的比表面积和丰富的中孔;添加钴改善了Ni_xCo_1-_x(OH)₂干凝胶的倍率性能,当钴含量达到24%时效果最佳;充放电后Co_xNi_1-_x(OH)₂干凝胶的晶态结构仍是β-Ni(OH)₂晶相结构,钴含量20%以上的Co_xNi_1-_x(OH)₂干凝胶充放电后微晶尺寸变化不明显;组成的活性炭/ Ni_0.76Co_0.24(OH)₂干凝胶电容器20 mA/cm²充放电循环时,库仑效率达到95%以上,循环100000次以上,电容器的比容量仍保持在90%以上。在长循环过程中,Ni_0.76Co_0.24(OH)₂干凝胶的微晶尺寸变化不大,微晶晶胞a轴逐渐变大、c轴逐渐缩小,晶胞参数趋向理想的β-Ni(OH)₂晶体。

Abstract: Ni_xCo_1-_x(OH)₂ xerogels were formed by sol-gel method under ambient pressure. The structure of these materials was characterized using N₂ (77 K) adsorption, XPS and XRD. Their capacitive performance was evaluated by using galvanostatic technique. The results show that the Ni_xCo_1-_x(OH)₂ xerogels materials have a well-developed mesopore structure. The rate performance of the Ni_xCo_1-_x(OH)₂ xerogels materials was greatly improved by Co impregnate, and the optimal amount of Co was 24%. The crystal structure of Ni_xCo_1-_x(OH)₂ xerogels is the same as that of the β-Ni(OH)₂. The crystallite size of the Ni_xCo_1-_x(OH)₂ xerogels will change largely except the amount of Co is above 20%. The electrochemical capacitor consisted with activated carbon and Ni_0.76Co_0.24(OH)₂ was cycled at a current density of 20 mA/cm², a coulombic efficiency above 95% and above 90% capacity retention after 100000 cycles were obtained. In the process long charge/discharge cycle, the crystallite size of the Ni_0.76Co_0.24(OH)₂ xerogels changes little, but the lattice parameter of the Co_0.24Ni_0.76(OH)₂ xerogels gradually shifts to the lattice parameters of the ideal β-Ni(OH)₂ crystal.

Key words: xerogel, NixCo1-x(OH)2 xerogels, electrochemical capacitor, galvanostatic technique
