摘　　要：从充放电性能、落后单格,以及活性物质的组成和形貌等方面,对市场上换新期内退返的电动自行车用铅蓄电池进行了研究。落后单格正极的上部和中部未有效参与反应,降低了正极容量,限制了整组电池的性能。In this paper,the repaired lead-acid batteries for electric bicycles during after-sale service were studied by the charge-discharge performance,disabled single cell and the composition and morphology of positive active materials.The upper and middle parts of the positive electrode of disabled single cell did not participate in the reaction effectively,which reduced the capacity of positive electrode and limited the performance of the whole group batteries.
