The invention relates to an EFB start-stop battery positive and negative 
electrode with high charge acceptance capacity and a preparation method thereof, belongs to the technical field of EFB start-stop batteries, and mainly solves the problem that the high-temperature life of a battery is reduced due to 
carbon fibers contained in existing lead paste. The main features are as follows: an 
anode lead paste formula includes 0.2% -- 0.4% of expanded 
graphite, 0.08% - 0.12% of short 
fiber, 0.1% - 0.3% of 
metal sulfate additive, 0.6% - 1.0% of 4BS seed, 9% - 12% of pure water, 8% - 10% of 1.38 g / cm3
sulfuric acid solution and the balance of lead 
powder; a 
cathode lead paste formula includes 0.1 to 0.2 percent of 
carbon nanotube slurry, 0.1 to 0.2 percent of 
carbon black A, 0.02 to 0.06 percent of 
carbon black B, 0.08 to 0.12 percent of short 
fiber, 0.15 to 0.25 percent of organic additive A, 0.08 to 0.12 percent of organic additive B, 0.5 to 0.8 percent of nanometer 
barium sulfate, 8 to 10 percent of pure water, 8 to 10 percent of 1.38 g / cm3 
sulfuric acid solution and the balance of lead 
powder. The invention has the characteristics of greatly improving battery charging acceptance capacity and further prolonging the battery life, and is mainly used for EFB starting and stopping batteries with high charging acceptance capacity.
