稀土元素镧对于电池板栅耐蚀作用的研究
Study on the corrosion resistance of rare earth element lanthanum on battery grids
摘要
Abstract
Rare earth metals can be used to make alloys,which can improve the properties of alloys,toughness,wear resistance,corrosion resistance and so on.In this study,La was doped in the grid Pb-Sn-Ca-Al alloy and La2(SO4)3 was added in the electrolyte.The effects of rare earth metal La on lead-acid batteries were investigated from multiple perspectives using electrochemical tests such as CV,EIS,LSV,and characterization methods such as FESEM,XRD,and XPS.The results show that add-ing La to the positive electrode grid refines the alloy grain and increases the overpotential of hydro-gen and oxygen precipitation.Lanthanum sulfate in the electrolyte can reduce the reaction current of the electrode plate and reduce the generation of dendrites.关键词
