- Besides , scan rate and cycle period also affect the result ; co - deposition of dualistic oxide is a focus of research , as an element in the same group , ir is selected . deposition rate of composition is decreased by the adding of ir composition , and when the proportion of ir exceeded 50 % , composition procession can be ceased . but cooperation of ir and ru oxide can highly increase the specific capacitance of active material ; annealing treatment under a certain temperature can help to change the hydrate ru composition into mixture state ru oxide , accordingly increase the stabilization of active material
研究表明:电解液的配制过程中,氯化钌浓度、溶液ph值、陈化时间、溶液温度对电镀效果均有影响,其中溶液ph值是最主要的影响因素;在仪器的使用条件探索中,理论结合实验确定了本电镀液体系循环伏安电势窗的理想范围,并发现循环伏安扫描速度和扫描周期对电镀结果也有较大影响;混合氧化物的共沉淀是目前研究热点,在此选用与钌同一族的铱作为共沉淀元素,铱的加入会阻碍氧化物的沉积速度,铱的比例超过50 %会使沉积作用停止,但是二元氧化物的协同作用使沉积的活性物质比容量大大提高;一定温度下退火后处理作用会使水合钌化物转变成混合价态的氧化钌,从而提高活性物质的稳定性。 - Results came as follows : in this dissertation , we found that it was the smallness of the positive electrode capacitance that limits the performance of carbon based supercapacitors in alkaline electrolytes , and the performance could be meliorated if the active material loaded on positive electrode increased . activated carbon electrode was proved to have good capacitor performances in neutral electrolyte such as ammonium sulfate solution and ammonium nitrate solution , but a correlated problem is the corrosion of the metal current collector
本文通过考察活性炭电极在碱性电解液中的电极行为，指出活性炭电极在碱性溶液中正极性能较差是影响碳基超级电容器性能的重要因素，增大正极活性物质的载量能够使电容性能得到一定程度的改善，同时发现活性炭电极在硫酸铵和硝酸铵等中性电解液中具有优越的电极性能，但存在金属集流体的腐蚀问题。 - Lithium secondary batteries are the future of chemical power sources on account of their properties such as high specific energy , portable , high working voltage , etc . since lithium possesses supreme high specific energy ( 3860ah / g ) and low potential ( - 3 . 036v , vs . h + / h2 ) , the increasing of battery ' s specific energy depends on the performance of positive active materials in large
锂二次电池以其比能量高,轻便,工作电压高等特点,成为化学电源未来的发展方向。由于锂负极的容量极大,所以锂电池比能量的提高很大程度上取决于正极材料的特性。目前广泛使用的正极材料锂金属氧化物( licoo2 , linio2 , limn2o4等)理论容量均在110 - 200ah / kg ,就电池的容量而言，可发展空间已很小。 - This product retained the complete nutrition ingredient originality in the fresh healthy placenta and activation many kinds of beneficial active material in the placenta , like the human body needs many kinds of amino acid , vitamin , trace element , immunity globulin and many kinds of active enzyme , it is the newest generation of high - level natural healthy nutrition food
