Battery packaging method and battery

Abstract

The invention provides a battery packaging method and a battery. The battery packaging method comprises the following steps: providing a to-be-packaged battery, wherein the to-be-packaged battery comprises a metal shell and an electrode arranged in the metal shell, and a gap is formed between the inner wall of the metal shell and the electrode; and filling the gap with a first filler and a secondfiller, so that the gap is filled with the first filler and the second filler, the inner wall and the electrode are separated through the first filler and the second filler, one of the first filler and the second filler is ceramic, and the other one of the first filler and the second filler is glass. The method is used for ensuring the safety of the battery and prolonging the service life of the battery.

Description

technical field [0001] 本申请涉及器件加工技术领域,具体而言,涉及一种电池的封装方法和电池。 Background technique [0002] 传统锂电池的金属外壳和电极密封为聚合物,燃料电池的金属外壳和电极采用玻璃金属封接,其他封装器件采用玻璃金属封接。 [0003] 聚合物属于有机材料、时间推移或者受热后容易老化、聚合物与电极金属结合强度低、造成电池漏气,电池寿命降低、不能更好地保证安全性,聚合物电极端子时间长了空气中的水分从金属件与聚合物结合处渗入电池内部、水与电池内部锂盐反应降低电池性能,同时对电池整体也有极强的腐蚀性、造成安全隐患。 [0004] 可见,现有的电池封装方式不能保证电池的安全性,电池的寿命也较短。 Contents of the invention [0005] 本申请实施例的目的在于提供一种电池的封装方法和电池,用以保证电池的安全性,提高电池的寿命。 [0006] 第一方面,本申请实施例提供一种电池的封装方法,包括:提供待封装的电池;所述待封装的电池包括金属外壳和设置在所述金属外壳内的电极,所述金属外壳的内壁和所述电极之间具有间隙;在所述间隙内填充第一填充物和第二填充物,以使所述间隙被所述第一填充物及所述第二填充物填满,所述内壁和所述电极之间通过所述第一填充物及所述第二填充物间隔开;其中,所述第一填充物和所述第二填充物二者之一为陶瓷,另一者为玻璃。 [0007] 在本申请实施例中,利用玻璃和陶瓷作为填充物来对金属外壳与电极之间的间隙进行填充,与现有技术相比,玻璃和金属的结合能够保证电池的气密性;陶瓷提高扭力和抗冲击强度,还能够保护电池在受到高温时可以充分绝缘。因此,通过该封装方法对电池进行封装能够保证电池在高温情况下的绝缘性,延长电池寿命,保证电池的安全性,并且使该电池能够应用于有扭力要求的器件或者设备,提高电池的适用性和实用性。 [0008] 作为一种可能的实现方式,所述间隙为环形间隙,所述在所述间隙内填充第一填充物和第二填充物,包括:沿所述环形间隙的轴向、径向或者周向交替填充所述第一填充物和所述第二填充物。 [0009] 在本申请实施例中,当间隙为环形间隙时,可以沿着环形间隙的轴向、径向或者周向交替填充两种填充物,保证两种填充物能够充分填满间...

AI Technical Summary

Problems solved by technology

[0003] Polymers belong to organic materials, which are easy to age after time passes or heated, and the bonding strength between polymers and electrode metals is low, resulting in battery leaks and reduced battery life, which cannot better ensure safety. Moisture seeps into the battery from the joint between the metal parts and the polymer, and the water reacts with the lithium salt inside the battery to reduce the performance of the battery. At the same time, it is also extremely corrosive to the battery as a whole, causing safety hazards

[0004] It can be seen that the existing battery packaging method cannot guarantee the safety of the battery, and the battery life is also short
