Embodiment Construction

[0037] Such as figure 1 As shown in -4, a battery includes a casing 100 , a cell 200 , a chip 300 , a casing cover 400 , an insulating film 500 and a fixing collar 600 .

[0038] The shell 100 is preferably a steel shell with good structural stability. For example, 304 steel deep-drawing material is used to pass through multiple progressive stamping dies, and it is stamped to the design specification size; the upper end of the shell 100 is opened 101, and the battery cell 200 occupies the shell 100 The main space inside is biased toward the lower end of the housing 100 , the chip 300 is located above the cell 200 , and the housing cover 400 is located above the chip 300 , and the opening 101 is closed by the housing cover 400 .

[0039]A layer of insulating film 500 is laid between the chip 300 and the battery cell 200, which can isolate the direct contact between the battery cell 200 and the chip 300 and avoid interference. The insulating film 500 can be prefabricated on the ...

Abstract

The invention provides a battery. The battery comprises a shell part, a battery cell part, a chip part and a shell cover part, wherein an opening is formed in the upper end of the shell part, the battery cell part, the chip part and the shell cover part are sequentially arranged in the shell part, and the shell cover part covers and seals the opening; an insulating film is laid between the chip part and the upper end part of the battery cell part, and the chip part is connected with the upper end part of the battery cell part through a first connecting piece penetrating through the insulatingfilm; a fixed lantern ring is arranged between the chip part and the shell part, the chip part and the shell part are connected through a second connecting piece, the fixed lantern ring is in close fit with the shell, and the second connecting piece is pressed on the shell part; wherein the lower end of the shell part is closed, a groove body is formed in the shell part, the lower end part of thebattery cell part is connected with the groove body through a third connecting piece, and the third connecting piece can be compressed by the battery cell part. The battery has the advantages of beingcompact in structure, convenient to assemble and good in explosion-proof performance.

Description

technical field [0001] The invention belongs to the technical field of secondary batteries, and specifically relates to a battery. Background technique [0002] Secondary batteries (also known as rechargeable batteries) have the advantages of high energy, high power discharge, and environmental protection. In recent years, they have been widely used in various portable electrical and electronic devices, such as toys and handheld devices. The energy storage capacity of secondary batteries puts forward higher and higher requirements. [0003] The normal operation of the rechargeable battery often needs to cooperate with other functional integrated circuit chips to achieve the ideal working effect. The current rechargeable battery is usually packaged by welding the battery cover. [0004] For example, Chinese patent application 201510321435.0 discloses a secondary electrochemical battery sealing body with a packaged chip shielding structure, including: a negative electrode cap...
