The experiments used carbon black (CB), activated carbon (AC), graphite carbon powder (Graphite Carbon, GC) and other additives into lead powder to make a lead paste, then through ripening and chemical processing steps. The produced active substances can effectively inhibit the crystal growth of lead sulfate and further increase battery cycle life (Cycle). The experiments included three groups of samples, 0.3 wt% GC + 0.3 wt% CB, 0.3 wt% AC + 0.3 wt% CB, 0.6 wt% GC, and two types of batteries, WP5-12/12 Volt 5Ah, WP6-12/12 Volt 6Ah, then analyzed their performances. The experiment used Raman spectroscopy and X-ray Diffraction (XRD) to measure the carbon materials properties and active substances. The appearances of the carbon materials and the active materials were observed by a Scanning Electron Microscope (SEM). Finally, the results show that 0.6 wt% GC with crystalline structure has a relatively high initial capacity of 4.97 Ah and 4.86 Ah, and it has relatively good energy efficiency in cyclic charge and discharge about ninety-eight percent.
