摘　　要：用循环伏安、电化学阻抗谱和塔菲尔曲线研究了制备工艺对铅酸电池正极板栅电化学行为的影响。在相同的时效温度下,炉温和勺温影响正极板栅在硫酸中的析氢和析氧能力。不同制备工艺的正极板栅的电荷转移电阻不同,最小的仅为0.16Ω·cm2,最大的可达21.3Ω·cm2,腐蚀电位也略有差异,最大与最小腐蚀电位的差值约为1.5 mV。Effect of preparation technologies on electrochemical behavior of lead-acid battery positive grid was studied by cyclic vohammetry, electrochemical impedance spectroscopy and Tafel curves. The ability of hydrogen and oxygen evolution of positive grid in sulfuric acid was effected by furnace temperature and spoon temperature. The charge transfer resistances of positive grid with different preparation technologies were different. The minimum and maximum values were 0. 16 Ω·cm^2 and 21.3Ω·cm^2, respectively. The corrosion potentials were changed slightly, the difference between the maximum and minimum ones was about 1.5 mV.
