Specifically, the alloy in T8 conditions showed higher susceptibility to severe localized corrosion than that in other conditions. During potentiodynamic polarization, the alloy in solution......
厚度增加而减小.与此同时,当电极厚度大于原电极设计(70 μm)时,放电截止时刻提前.这是由于正极厚度增加极片中的可循环锂离子总量增加,在保持负极厚度不变时,负极所能荷载的锂离子有限,充电末期锂离子嵌入负极的壁垒势能也越大,从而抑制了锂离子嵌入负极,导致提前结束放电过程. 图4 不同正极厚度下电极极化过电势变化曲线 Fig. 4 Polarization... for lithium ion battery[J].

that three stabilizing agents for water quality can all increase cathode polarization of zinc electrolysis process from the results of linear sweep voltammetry in 0.5 mol/L ZnSO4 solution. Under 4 A/dm2 polarization current, the potential of cathode polarization moves negatively 0.030 V or 0.051 V at least at 25 ℃ or 40 ℃. Moreover, the Tafel slope (bc) of zinc reduction process raises about 25......

in the medium of marine microorganisms was investigated by electrochemical impedance spectra, polarization curves, and so on. Experimental results showed that the corrosion potential of carbon steel moved in a negative direction in the unpurified marine microorganism solution, and the polarization style of the cathodic process did not change. The electrochemical impedance spectra showed that the impedance......
