【摘要】 用湿合成法合成了尖晶石结构的纳米级LiMn₂O₄粉末,并将其作为电化学超级电容器电极材料,经组装成模拟双电层电容器,用电池测试仪测其电容量,经换算,得到该失晶石结构的纳米级LiMn₂O₄的单位比容量可达到860F/g（在1.25～0.7V之间充放电时）,且有良好的相对平台,为电化学超级电容器的实际应用开辟了又一新途径。更多还原

【Abstract】 In this paper, the nanometer grade spinal LiMn₂O₄ were synthesized by the authors with wet-method. Afterbeing examinated by TEM, SEM, XRD, which were used as the electrochemical supercapacitors’ electrode ma terial.With which the simulant double electric capacitors were assembled and the capacitors’ capacitance were tested bybattery testing instrument. After conversion, the specific capacitance of the LiMn₂O₄ was 860F/g （charging-dischargingranging from 1.25V-0.7V）, moreover, the discharging figure displayed a relative flat. Thus the authors thought whichwas a new way to enlarge the factual use of the electrochemical supercapacitors.更多还原
