▎ 摘　　要

NOVELTY - Conductive paste comprises 3-8 wt.% conducting agent, 4-15 wt.% hydrofluoric acid and 1-1.3 wt.% oligomeric carbon hydroxide solution, where the mass ratio of the oligo-hydrocarbon solution to the conductive agent is (1-15):1. USE - Conductive paste used for preparation of carbon-coated foil in a lithium-ion battery with strong corrosion resistance (all claimed) in consumer electronic field and power battery field. ADVANTAGE - The conductive paste improves the pole piece bonding force, electrolyte corrosion resistance of the pole pieces and cycle performance of the prepared battery, ensures the conductive performance, prevents the corrosion of the electrolyte to the aluminum foil, provides a strong corrosion resistant coating carbon aluminum foil lithium ion battery with good conductivity and bonding property. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: 1. a method for preparing carbon-coated foil, which involves: coating on the surface of the foil, and then drying, sintering, and rolling to obtain a product; 2. a carbon-coated foil; and 3. a strong corrosion-resistant lithium-ion battery, which comprises a carbon-coated foil.
