摘要: Abstract A series of novel Pb–Te binary alloys with different contents tellurium (0.01–1.0 wt.%) were investigated as the positive grid a lead acid battery. The microstructure was observed using polarizing microscope. morphology corrosion layers and corroded surfaces Pb alloy electrodes analyzed by scanning electron microscopy (SEM) following test. electrochemical properties Pb–Te–Sn in sulfuric solution cyclic voltammetry (CV), open circuit potential (OCP), impedance spectroscopy (EIS), alternating current (ACV), linear sweeping (LSV). results indicate that introduction grain refinement, increased resistance, an accelerated oxygen evolution reaction for alloys. passive films formed on shows improved performances comparison to those Pb–Ca–Sn alloy.
