▎ 摘  要

NOVELTY - Start-stop battery anode paste, comprises 0.1-1.0 wt.% of carbon fiber, 0.1-0.5 wt.% of graphene, 1.0-3.0 wt.% of graphite, 3.0-8.0 wt.% of 4BS seed, 5-10 wt.% of dilute sulfuric acid, 0.01-0.1 wt.% of rare earth, the balance of lead powder. USE - Start-stop battery anode paste used in starter battery containing lead paste (claimed). ADVANTAGE - The start-stop battery anode paste prolongs cycle life, and has high battery capacity, and maintains charging and discharging capacity. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing start-stop battery anode paste, which involves: (A) diluting the graphite into the emulsion for stand-by, and placing the carbon fiber, graphite, 4BS seed and rare earth into the cream and lead powder in 0.8 tons of vacuum and paste machine, first into the 1/3-1/2 amount of lead powder, stirring for 5 minutes; (B) adding the remaining lead powder, stirring for 5 minutes; (C) adding water and stirring for 2 minutes; (D) adding graphene emulsion, then the dilute sulfuric acid, while stirring 15 minutes, and controlling the maximum temperature at 75 degrees C for 3-5 minutes; (E) cooling to a temperature difference of 5 degrees C with the ambient temperature; and (F) measuring the apparent density in line with the requirements.
