Abstract: The effects of active carbon with high specific surface area on the microstructure and electrochemical properties of the negative electrode active material of lead-acid battery were studied. The results show that the addition of 0.5% SPC04 type active carbon into negative electrode is able to increase the discharge capacity of the negative electrode at 1C, 5C and 10C rates by 18.36%, 42.68% and 44.01%, and the discharge cycle life of the ne-gative electrode at 2C 60 s is doubled. The test results of 6-FM-9F type battery show that not only under high-rate partial-state-of-charge (HRPSoC) conditions, but also under full-charge and full-discharge conditions the cycle life has been significantly improved. Through the analysis of the microstructure of active material, it is believed that the addition of active carbon can significantly change the particle morphology and pore structure. The addition of active carbon can make the particles and pore distribution of the negative electrode more uniform, the size of the particle is moderate, and the ratio of the effective aperture range (about 0.4—3 μm) between the particles of the active material is increased.
