ROPEX 脉冲热封解决方案,值得您的信赖
电池电芯薄膜密封的最优生产工艺
真空封边
采用 ROPEX 脉冲热封技术对软包电池进行密封,确保防水性能,并在真空环境下注入电解液。注液过程中会产生气体,在外部压力作用下被压入气袋。随后,利用 ROPEX 脉冲热封技术对电芯与气袋之间的区域进行最终封合,实现可靠密封。
气袋穿刺
在气袋牢固密封后,可进行穿刺并抽出其中气体。
气袋裁切
随后将气袋裁切分离。 得益于密封封边的高密封性,裁切后的软包电池仍可获得最佳防护效果。
中间工艺
ROPEX 脉冲热封技术可确保所有密封边在裁切后,即便在严苛工况下仍保持密封性能,有效阻隔湿气与氧气侵入。
折叠工艺步骤 1
对密封边进行折叠,必要时可进行粘合处理。
折叠工艺步骤 2
通过对凸出部位进一步折叠,进一步缩小软包电池体积。
成品展示
最终得到密封可靠的软包电池。得益于脉冲密封技术,电池可完美适配后续老化工艺。
