摘要
The differences of electrochemistry performance between the purchased lead carbonate and the prepared lead carbonate were studied by the methods of cycle voltammogram, electrochemical impedance spectroscope (EIS), constant current discharge, thermal gravimetric analysis, and scan electron microscope (SEM) etc. in the paper. It was showed that the reacting activity of the prepared lead carbonate was higher than that of the purchased lead carbonate. And several points of view were concluded as follows. (1) The prepared lead carbonate contains chemical structure water, but the purchased lead carbonate doesn’t contain chemical structure water. (2) The main chemical substance in the purchased lead carbonate powder is PbCO3, while the one in the prepared lead carbonate powder is 2PbCO3·Pb(OH)2. (3) The particle size of the prepared lead carbonate is smaller than that of the pur- chased lead carbonate.
