Abstract

In a positive electrode current collector for a lead-acid battery including a coating of tin dioxide formed on the surface of a current collector substrate of titanium or a titanium alloy, the half width of a peak with the maximum intensity among peaks of tin dioxide in the x-ray diffraction pattern of the positive electrode current collector for a lead-acid battery is 1° or lower.

Claims

exact text as granted — not AI-modified
1 : A positive electrode current collector for a lead-acid battery comprising a coating of tin dioxide formed on the surface of a current collector substrate of titanium or a titanium alloy, 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. 
     
     
         2 : A positive electrode current collector for a lead-acid battery comprising a coating of tin dioxide formed on the surface of a current collector substrate of titanium or a titanium alloy, wherein crystals of said tin dioxide are selectively oriented in 1 or more and 4 or less of the crystal planes. 
     
     
         3 : The positive electrode current collector for a lead-acid battery according to  claim 2 , wherein said crystal planes oriented are a ( 110 ) plane, a ( 101 ) plane, a ( 200 ) plane, a ( 211 ) plane, a ( 220 ) plane, a ( 310 ) plane, a ( 112 ) plane, or ( 301 ) plane. 
     
     
         4 : The positive electrode current collector for a lead-acid battery according to  claim 1 , wherein said coating contain antimony or fluorine. 
     
     
         5 : A lead-acid battery comprising said positive electrode current collector according to  claim 1 . 
     
     
         6 : The lead-acid battery comprising said positive electrode current collector according to  claim 4 . 
     
     
         7 : The positive electrode current collector for a lead-acid battery according to  claim 2 , wherein said coating contain antimony or fluorine. 
     
     
         8 : The lead-acid battery comprising said positive electrode current collector according to  claim 7 . 
     
     
         9 : The positive electrode current collector for a lead-acid battery according to  claim 3 , wherein said coating contain antimony or fluorine. 
     
     
         10 : The lead-acid battery comprising said positive electrode current collector according to  claim 9 . 
     
     
         11 : A lead-acid battery comprising said positive electrode current collector according to  claim 2 . 
     
     
         12 : A lead-acid battery comprising said positive electrode current collector according to  claim 3 .
