PURPOSE:To improve the strength of an electrode plate and electric conductivity by laminating a specific alloy sheet material on the surface of the substrate of a required metal thin plate. CONSTITUTION:A lead-tin alloy sheet material with the tin content 0.05wt.% is laminated on the surface of the substrate of a copper metal thin plate to form an electrode plate for a lead-acid battery, then the mechanical strength, electric conductivity and corrosion resistance are improved. |
