摘　　要：对LR20电池的封口工艺进行研究。与对轮轴向旋压卷边工艺制备的电池相比,采用盔口套压工艺制备的LR20电池,集流体爆破压力提高6.7%,70℃高温漏液率降低4%,卷边压力提高5.9%,短路截止爆炸率降低3%,具有更好的安全性能。Sealing process for LR20 battery was studied. Compared to the battery with axial feed opposite roller spinning crimping process,the bursting pressure for current collector of the LR20 battery sealed by helmet pressing process was increased by 6. 7%, high-temperature leakage rate at high temperature 70℃ was decreased by 4%, crimpling pressure was increased by 5.9% , the short-circuit cut-off bursting rate was decreased by 3%, the safety performance was demonstrated.
