摘　　要：采用恒流放电和交流阻抗技术研究碱锰电池150 mA连续放电过程中正负极电化学行为的变化。结果表明:在LR6型碱锰电池150 mA连续放电过程中,电压的变化主要由正极极化引起的;而在放电末期,电压的下降主要是由负极区碱浓度的降低以及负极阻抗的升高所引起的。The electrochemical behaviors of a cathode and an anode during the discharge in alkaline Zn/MnO2 primary cells were investigated through 150 mA constant current discharge and electrochemical impedance spectrum（EIS）.The results show that the cathode potential is the main cause of the voltage drop during the first discharge step of an alkaline Zn/MnO2 cell,while the voltage drop during the latter process of discharge is resulted from the dropped concentration of KOH solution and the increased resistance of anode.
