Abstract
Official abstract text for this publication.
An electrolyte composition and a battery is provided. The electrolyte composition includes graphene. The electrolyte composition of the present invention is suitable for a battery and can improve the life cycle of the battery. The application process of the electrolyte composition of the present invention is simple and more cost-efficient as compared to conventional techniques which add carbon material(s) to a battery. The present invention is effective in improving battery performance.
First claim
Opening claim text (preview).
What is claimed: 1. An electrolyte composition comprising water, sulfuric acid and graphene, wherein graphene is present in an amount of about 0.001 wt % to about 1 wt % based on the total weight of the electrolyte composition and is modified with hydrophilic groups, wherein the modified graphene has a lateral dimension from 20 nm to 1 μm and a thickness from 0.35 nm to 10 nm. 2. The electrolyte composition according to claim 1 wherein hydrophilic groups are selected from the group consisting of hydroxyl group, amino group, carboxyl group, carbonyl group, phosphate group and a combination thereof. 3. The electrolyte composition according to claim 1 wherein the modified graphene has a carbon content of more than about 80 mol % and an oxygen content from about 1 mol % to about 20 mol %. 4. The electrolyte composition according to claim 1 , having a specific gravity from about 1.12 to about 1.28. 5. The electrolyte composition according to claim 1 , having a resistance of no greater than 600Ω. 6. The electrolyte composition according to claim 5 , having a resistance of 100 to 600Ω. 7. A method comprising incorporating the electrolyte composition according to claim 1 in a lead-acid battery. 8. A battery comprising the electrolyte composition of claim 1 .
