摘要
研究了镀铅泡沫碳化硅集流体的结构对铅酸蓄电池极板的设计参数、正极活性物质利用率的影响.镀铅泡沫碳化硅集流体明显降低了集流体的表观密度和阳极板的γ参数,显著提高了活性物质的利用率,延长了电池的循环寿命.集流体的"三明治"结构改善了极板内的电流分布,降低了电压降,明显提高了铅酸蓄电池活性物质的利用率和大电流放电的能力.
The influence of structure design of Pb-plated reticulated SiC current collector on the plate design parameters and utilization efficiency of PAM of lead-acid batteries was studied. The apparent density of reticulated positive current collectors and parameter γ of the plate were decreased, and the utilization efficiency of PAM and the cycle life of the batteries were improved. Using the sandwich current collector, which has a dense SiC interlayer between the two reticulated SiC, the current distribution and voltage loss in positive grid were improved, which resulted in the significant enhancement of the utilization efficiency of PAM and the ability of discharging with large current.
