Abstract��The distribution of Pb and S elements around the negative electrode Pb of the lead-acid battery was tested by the surface analysis instrument to describe the crystallization of PbSO4 in the negative electrode. In the different aging (Aged) experimental stages��the effective life of the battery was evaluated through the accumulation distribution of PbSO4. Characteristics of EPMA in the micro-area distribution test were shown through the test of the lead-acid storage battery anode material. The performance difference between EDS and WDS�� and the characteristic difference between SEM��WDS and EPMA were compared. The results showed that EPMA had prominent advantages in resolution and sensitivity of the microprobe analysis�� especially in the analysis of the low content elements.
