Abstract
Official abstract text for this publication.
A method for manufacturing a substrate for a lead acid battery includes manufacturing a powder mixture by mixing lead powder and carbon powder and manufacturing a substrate by compress-molding the powder mixture. 85 wt % to 95 wt % of the lead powder and 5 wt % to 15 wt % of the carbon powder are mixed, based on 100 wt % of the powder mixture.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for manufacturing a substrate for a lead acid battery, comprising: manufacturing a powder mixture by mixing lead powder and carbon powder; and manufacturing the substrate by compress-molding the powder mixture, wherein 85 wt % to 95 wt % of the lead powder and 5 wt % to 15 wt % of the carbon powder are mixed, based on 100 wt % of the powder mixture, and wherein the lead powder comprises 40 wt % to 75 wt % of lead powder having a particle diameter of 10 μm to 50 μm and 25 wt % to 60 wt % of lead powder having a particle diameter of 200 μm to 250 μm, based on 100 wt % of lead powder. 2. The method of claim 1 , wherein the lead powder is Pb—Sn—Ca alloy powder. 3. The method of claim 1 , wherein the carbon powder comprises graphite, carbon black, or carbon nanotube. 4. The method of claim 1 , wherein the carbon powder has an average particle diameter of 1 μm to 5 μm. 5. The method of claim 1 , wherein the powder mixture is compress-molded at a temperature of 25° C. to 150° C. with a pressure of 50 ton to 200 ton.
