Patent ID: 8402620

Claim:
A method for producing a lead-acid battery, comprising: providing an organic solvent solution comprising an organotin compound, and antimony; and spraying the solution on a surface of a current collector substrate of titanium or a titanium alloy to produce a positive electrode current collector for a lead-acid battery comprising a coating of tin dioxide containing antimony formed on the surface of the current collector substrate, wherein the half width of a peak with the maximum intensity among peaks of tin dioxide in the x-ray diffraction pattern of said positive electrode current collector for a lead-acid battery is 1° or lower, wherein crystals of said tin dioxide are selectively oriented in crystal planes, the number of the crystal planes selectively oriented being 1 to 4, wherein a (200) plane is the maximum among the crystal planes, wherein the coating has been made by an intermittent repeat of spraying said solution, wherein each of the spraying has formed a layer of said tin oxide, each layer of the tin oxide having a thickness of 5 nm or less.
