▎ 摘　　要

NOVELTY - A graphene fiber-containing lead paste comprises graphene fiber, water and lead powder. USE - The graphene fiber-containing lead paste is useful in battery negative and positive plates, where the battery is a lead-acid battery (all claimed). ADVANTAGE - The graphene fiber-containing lead paste can be prepared in a simple with high yield, and can effectively improve the charging current of battery and prolong the service life of battery. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) preparation of graphene fiber-containing lead paste, which involves mixing and stirring raw materials in above-mentioned lead paste, discharging paste to obtain graphene fiber-containing lead paste, and drying and mixing the paste for 30 minutes, where the apparent density of the lead paste is 4-4.6 g/cm3; (2) battery negative electrode plate, which comprises plate grid and graphene fiber-containing lead paste; (3) battery positive electrode plate, which comprises plate grid and graphene fiber-containing lead paste; (4) producing battery negative and positive plate, which involves coating graphene fiber-containing lead paste on plate, curing, and drying; and (5) battery, which comprises graphene fiber-containing lead paste, negative electrode plate and/or positive electrode plate.
