Abstract

The invention provides a liquid storage device and battery formation equipment. The liquid storage device comprises a suction nozzle, a liquid storage cup and a sealing cover, wherein the sealing cover is connected with a top opening of the liquid storage cup, the bottom of the liquid storage cup communicates with the suction nozzle, the sealing cover comprises a sealing connection ring and a temperature reduction cover, the temperature reduction cover is connected with the liquid storage cup by the sealing connection ring and is arranged in a liquid storage cavity of the liquid storage cup, and a cooling cavity is formed in the temperature reducing cove and is provided with an opening facing a direction of the bottom of the liquid storage cup. In the liquid storage device provided by the invention, a gasified electrolyte can be rapidly liquefied by a cooling and temperature reduction effect of the temperature reduction cover and reflows to the liquid storage cavity along an inner wall of the cooing cavity, so that the volatilization and the loss of the electrolyte can be effectively reduced, and the production cost is reduced.

Description

technical field [0001] 本发明属于电池生产技术领域,更具体地说,是涉及一种储液装置及包含该储液装置的电池化成设备。 Background technique [0002] 目前,动力电池已经被广泛应用于汽车、通信、航空航天等领域,电池化成作为电池生产过程中的关键工序关系到电池的品质和质量并直接影响电池的生产成本。在电池进行化成时,需要通过化成设备对电池进行充放电操作,化成负压系统完成化成过程中的电解液抽取和返回等工作,其中的储液装置的功能是在化成进行时通过负压抽取电池在化成时产生的气体与溢出的电解液,存储在储液装置中,在电池化成后通过微正压空气将没有挥发的电解液注入电池内。现有的储液系统往往不能对气化的电解液进行有效的收集,在一定程度上造成了材料的浪费。 Contents of the invention [0003] 本发明的目的在于提供一种储液装置,以解决现有技术中存在的不能对气化的电解液进行有效收集的技术问题。 [0004] 为实现上述目的,本发明采用的技术方案是:提供一种储液装置,包括:吸嘴、储液杯及密封盖,所述密封盖与所述储液杯的顶部开口连接,所述储液杯的底部与所述吸嘴连通,所述密封盖包括密封连接环及降温罩,所述降温罩通过所述密封连接环与所述储液杯连接,所述降温罩位于所述储液杯的储液腔内,且所述降温罩的内部设有向所述储液杯底部方向开口的冷却腔。 [0005] 进一步地,所述降温罩为金属构件。 [0006] 进一步地,所述降温罩的壁厚从所述降温罩的底部至顶部的方向逐渐增大。 [0007] 进一步地,所述冷却腔的侧壁上设有若干个围绕所述冷却腔的中轴均匀分布的散热槽。 [0008] 进一步地,所述冷却腔的内壁上设有散热层。 [0009] 进一步地,所述密封盖还包括设于所述降温罩顶部且与所述冷却腔连通的排气管。 [0010] 进一步地,所述排气管的外周设有安装环,所述安装环的中部设有密封环槽,所述密封连接环的内壁上设有与所述密封环槽相配合的密封凸环。 [0011] 进一步地,所述密封盖还包括设于所述降温罩侧壁上的至少一个能连通所述储液腔与所述冷却腔的稳压气孔。 [0012] 进一步地,所述稳压气孔具有至少两个,且所述稳压气孔围绕所述冷却腔的中轴均匀分布于所述...
