采用"固相"模板合成法和特殊的分离提纯工艺制备得到纯净的四羧基取代镍酞菁有机配合物,将其分别与一定比例的导电剂I2混合掺杂,采用球磨分散法制备得到酞菁活性纳米颗粒.以锂片作为负极,考察该纳米活性颗粒的电化学性能,并分析其羧基官能团导电机理.制备的酞菁纳米活性颗粒在0.3~3.2 V截止电压下的初始放电容量为852 mA·h/g,经过20次循环后的放电容量迅速下降到400 mA·h/g左右,此后保持平稳,在第55次循环后的比容量仍然保持300 mA·h/g,初步研究表明具备一定的电化学活性.

Pure carboxyl substituted nickel phthalocyanine complexe (Ni-Pc) was obtained using the "solid phase"template synthesis method and special process of separation and purification. The Ni-Pc active material was mixed with iodine and ball milled to obtain the Ni-Pc nanoparticles. The electrochemical performance of the nanoparticles was investigated using lithium plate as counter electrode. The initial discharge capacity of Ni-Pc nanoparticles is 852 mA·h/g in cutoff voltage of 0.3-3.2 V. After 10 cycles,the specific capacity decreases rapidly and reaches a stable value. And the discharge capacity remains at 284 mA ·h/g after 55 times recycling. The primary study indicates that the Ni-Pc nanoparticles compounds show good electrochemical properties.
