一般描述

硫酸七水合物镍(II)是一种水溶性固体,广泛应用于电化学、催化、电子、光电子等工业领域。它的电化学特性使它成为合成电极材料的重要组成部分,广泛用于电池、超级电容器和燃料电池。

应用

七水合硫酸镍可用于研究和开发: 
  • 作为重要前体,通过共沉淀法生产锂离子电池的富镍正极材料(NMC, NCA),因为它简单,易于放大,并且能够在颗粒尺度上产生均匀的结构。      
  • 在电沉积工艺中作为镍源制备Ni-NTNW(镍纳米管网络),然后在Ni-NTNW表面涂覆电活性NiCo-LDH材料,形成层叠式超级电容器电极。  
  • 作为合成肉桂酸镍配合物的前体,肉桂酸镍配合物是制备金属螯合单体的关键组分。
  • 与其他金属硫酸盐合成高效析氧反应(OER)三金属Fe-Co-Ni电催化剂。
  • 合成用于涂层的高熵合金,以提高涂层的硬度、耐磨性和耐腐蚀性。

特点和优势

  • 高纯度,痕量金属分析(=< 15 ppm) 32种元素,适用于电池。   
  • 高水溶性,非常适合合成各种复合材料。
  • 低ppm水平的金属离子,包括Al、K、Na、Mg、Cu、Co等7)      99.999%纯度,非常适合镀镍。
