中文摘要:
      采用水热电沉积法在泡沫镍基体上原位沉积Co9S8薄膜,并对其形貌、组成、结构和电化学性能进行表征和测试。结果表明,镍基Co9S8薄膜呈花瓣片状,并具有优异的电化学性能,其在电流密度为10 mA/cm2时,比电容高达为2538.7 F/g。即使电流密度扩大至50 mA/cm2时,比电容依然可达1930.7 F/g。经过1000次循环(电流密度为20 mA/cm2 ),比电容仍可达为1825.2 F/g,电容保有率72.8%,经过1500次循环后,电容保有率61.4%。

英文摘要:
      A Co9S8 film was in-situ deposited onto nickel foam substrate via a hydrothermal electrochemical deposition method. The morphology, composition and structure of the as-prepared film were characterized and the electrochemical performances were tested. The result showed that the as-synthesized Co9S8 film displayed a petal-like morphology and possessed excellent capacitive behavior with a specific capacitance of 2538.7 F/g at a discharge current density of 10 mA/cm2, and retained to 1930.7 F/g even at a higher density of 50 mA/cm2. After 1000 cycles at 20 mA/cm2, the specific capacitance of 1825.2 F/g still remained, and the capacitance retention is calculated to be 72.8%. Even after 1500 cycles, the specific capacitance retention could retain to 61.4%.
