Experiments results showed that the doping of co can improve the electrochemical properties of nickel hydroxide and foam nickel electrode , such as discharge specific capacity , utilization of active material , cyclic performance 掺杂co可以明显提高泡沫镍电极的放电比容量,提高ni ( oh ) _ 2的活性物质利用率和充放电循环性能。
However , the insulating nature of sulfur and polysulfides and the loss of polysulfides in the liquid organic electrolyte make lithium - sulfur batteries have very low positive active material utilization and poor cyclability 但是单质硫及其放电产物导电性差,易溶于有机溶剂,使得锂-硫电池正极活性物质利用率低、循环性能差等。
However , previously reported li / s batteries encounter many serious problems , including very low active material utilization and poor rechargeablity , which inhibit the commercialization of rechargeable li / s batteries 本论文设计并制备了纳米级颗粒的导电聚合物硫以及活性炭硫两类复合材料作为锂电池正极用电化学活性物质。
Lead acid batteries had a disadvantage of low specific energy by weight as motive power sources of electric vehicles . the utilization of active material was one of the most important factors that affected the specific energy 铅酸电池作为电动车用动力电池存在着重量比能量低的缺点,而活性物质的利用率是影响比能量的一个重要因素。
The main factors influencing the specific energy by weight included current density , plate thickness , active material structure , the conductivity of active material , grids , electrolyte volume and density 影响铅酸电池活性物质利用率的主要因素有:电流密度、极板厚度、活性物质的结构、活性物质和板栅的导电性能及电解液的体积和密度等。
