摘要:
对一种基于高分子材料修复液的铅酸蓄电池修复再生技术进行了修复效果验证,通过测试修复前后的蓄电池容量和内阻,发现该修复技术对一些失效蓄电池有明显修复效果,能降低蓄电池内阻并将容量恢复到额定容量以上,但对另外一些严重失效的蓄电池则效果有限.高温加速老化试验显示,修复成功的蓄电池能够经受至少5个周期老化试验,说明修复后预期使用寿命在5年以上.通过对修复前后蓄电池的极膏进行X射线衍射和扫描电子显微镜测试,发现该修复技术对不可逆硫酸铅晶体有较好的分解转化作用,从而使蓄电池得到修复.
Abstract:
Effect of a kind of restoration and regeneration technology of valve regulated lead-acid battery (VRLAB)based on high-polymer repairing solution was verified. By testing capacity and internal resistance of the batteries before and after res-toration,this technology was found to be obviously effective in repairing some disable batteries which was able to reduce in-ternal resistance of batteries and restore capacities to exceed rated capacities. But it was also found to be limited in restoring some batteries of serious failures. High-temperature accelerated aging test showed the successfully restored battery could ex-perience at least five periods of aging tests,which meant at least five years of expected service life after restoration of the battery. By means of X-ray diffractometer (XRD)and scanning electron microscope (SEM)tests on the electrode of battery before and after restoration,this technology was found to have preferable decomposition and transformation effect on irre-versible lead sulfate crystals,which meant it was able to restore the battery well.
