Chitosan, extenders anointed and <i>in-situ</i> synthesis method were used to synthesize anode-composite lead-carbon batteries.SEM, EDS, BET and RM were used to characterize and analyze the morphology of carbon materials.The results show that chitosan-carbon has non-crystal structures.Its pore size distribution is between 5-10nm.Specific surface area reaches to 487.4m²/g.The negative composite material electrode is mixed with a conductive agent to produce pastel.Pb-C analog battery was assembled.Electrochemical workstation is used to test chronoamperometry curves, electrochemical impedance spectroscopy so as to evaluate the possibility of <i>in-situ</i> synthesis anode composite material and its potential value of practical application.Electrochemical testing results show that the Pb-C negative plate,which is made by anode composite carbon material as the carbon source of <i>in-situ</i> synthesis of chitosan, possessing better electrochemical performance and smaller resistance.Its specific capacitance of cyclic voltammogram test is 162.9F/g with longer first discharge platform,the ultimate capacity reaches to 108.722mAh&#183;g^-1 when chitosan as carbon source, the specific capicity is 98% of the theoretical capacity. After 1000times of cycle there is almost no decay in capacity.
