摘　　要：从抽真空时间和真空度两方面对阀控式AGM铅酸电池抽真空灌酸后极板的渗酸效果进行了研究。根据电池电解液液面的高度、极板四周与中心部位铅膏的含水率、活性物质微观形貌三方面对极板的渗酸效果进行表征。试验结果表明,延长抽真空时间和降低真空度值均能有效改善极板的渗酸效果。In this paper,the acid infiltration effect of the plate of valve-regulated AGM lead-acid battery was studied from two aspects of vacuum time and vacuum degree.The acid penetration effect of the plate was characterized according to the height of the electrolyte surface,the moisture content of the lead paste around and in the center of the plate,and the morphology of the active materials.The test results show that extending the vacuum time and reducing the vacuum degree can improve the acid penetration effect of the plate effectively.
