Abstract
Official abstract text for this publication.
An electrolyte composition for a lead storage battery and a lead storage battery using the same are provided. More particularly, the electrolyte composition of a lead storage battery and the lead storage battery using the same improve stratification of an electrolyte without use of a separate mechanical device by using a natural stirring effect caused by a specific gravity difference between a dispersant having a specific gravity of from about 1.02 to about 1.35 and an electrolyte including distilled water and sulfuric acid. Due to the reduction in mechanical components, the electrolyte composition for a lead storage battery and a lead storage battery disclosed herein have enhanced durability compared to conventional batteries.
First claim
Opening claim text (preview).
What is claimed is: 1. An electrolyte composition for a lead storage battery comprising: distilled water, sulfuric acid, and a dispersant having a specific gravity of 1.02 to 1.35, wherein the dispersant is a mixture of a filler and a polymer resin selected from the group consisting of polypropylene, polyvinyl chloride, and polyethylene, and wherein the dispersant mixture has a weight ratio of from about 70% to about 75% polymer resin and from about 25% to about 30% filler. 2. The electrolyte composition of claim 1 , wherein the filler is talc, mica, or a mixture thereof. 3. The electrolyte composition of claim 1 , wherein the electrolyte composition comprises 30 to 65 wt % of the distilled water, 34.9 to 40 wt % of the sulfuric acid (H2SO4), and 0.1 to 30 wt % of the dispersant. 4. The electrolyte composition of claim 1 , wherein the dispersant is formed in a powder shape and has an average particle size of from about 1 μm to about 20 mm. 5. The electrolyte composition of claim 4 , wherein the dispersant shape is selected from a group consisting of a spherical shape, a plate-like shape, a cylindrical shape, and a tetrahedral shape. 6. A lead storage battery comprising the electrolyte composition of claim 1 . 7. The electrolyte composition of claim 1 , wherein the dispersant is a mixture of a first dispersant having a specific gravity of 1.02 to 1.27 and a second dispersant having a specific gravity of 1.271 to 1.35.
