The utility model belongs to the field of lithium battery structure and manufacturing technology, in particular to a soft-packed lithium battery pack. The shell comprises a shell, a core arranged in the shell, an upper cover at the opening end of the buckling shell and a plastic edge layer. The shell comprises a bottom shell formed in one body. The side of the upper cover is a vertical plane, and the four corners of the upper cover are chamfered with the four corners outside the buckling of the opening end of the shell, so as to facilitate the retention of gaps. The integrated forming shell does not need special welding procedure of the bottom shell, which saves the cost. The side face of the upper cover is a vertical plane, and the four corners of the upper cover and the four corners outside the opening end of the shell are chamfered with gaps. When the core is used improperly or the ambient temperature is too high, the pressure in the shell can be relieved by the rapid release of the gap at the chamfer, which plays an explosion-proof role. At the same time, the side of the upper cover is vertical plane, and the welding is smooth and easy. Therefore, the production cost of the flexible packaged lithium battery pack of the utility model is low, and the structure of the shell of the utility model makes the use of the battery safer and more reliable.

一种软包锂电池组
本技术涉及锂电池结构及制造
,尤其涉及一种软包锂电池组。
技术介绍
现有的一次9V电池的容量、储存性能和体积不能很好地满足要求。现有9V电池包正极、负极、塑胶绝缘片、正负极连接片,它们之间依靠铆钉铆接方式连接,组成一种特殊的绝缘端子。金属上盖、金属外壳、金属下盖之间采用激光焊接或者氩弧焊接方式连接,下盖设计有排气孔;9V电芯三只串联组合形成一个9V电池组,正负极连接片与电芯连接片点焊方式连接,并焊接有过流过温保护电子元件(组)包括PTC、热敏元件;绝缘胶纸以及绝缘片和绝缘盖、标贴有效的起到绝缘和保护作用。但这种壳体与上、下盖完全分开,使用时,需要将下盖焊接上壳体,增加工序,同时为防爆,需要在下壳体上打孔,工序复杂。生产成本高。
技术实现思路
针对上述技术缺陷,本技术提供一种工序简单,生产成本低,防爆效果好的软包装锂电池组。为解决上述技术问题,本技术提供的技术方案是:一种软包锂电池组,它包括外壳、设于外壳内的电芯、扣合外壳开口端的上盖以及塑胶绝缘层,所述的外壳是包括一体成形的底壳;所述的上盖的侧面是垂直平面,且上盖的四角与外壳开口端扣合外的四角均倒角 ...
