Abstract
The invention discloses an explosion-proof device for a lithium ion battery, relates to a battery explosion-proof technique and aims to provide the explosion-proof device for the lithium ion battery, which meets the explosion-proof requirement of a battery with an aluminum shell and has simple technique and low cost. The technical solution is that: the explosion-proof device comprises a cover plate and an explosion-proof film; a bottom surface of the cylindrical explosion-proof film arranged in a big-step hole of the cover plate is opposite to a small hole of the cover plate; and an annular clamp ring is in close fit with the cylindrical explosion-proof film and the wall of the big-step hole of the cover plate. The explosion-proof device is used for preventing explosion of the lithium ion battery.
Description
Technical field:
The present invention relates to a kind of explosion-protection equipment of battery anti-explosion technology, particularly a kind of lithium ion battery.
Background technology:
Lithium-ion-power cell is because capacity is big, blast easily, the explosion-protection equipment of existing lithium battery, be by welding method rupture pressure disc (Copper Foil) to be fixed on the hole of cover plate on the stainless steel cover plate, the welding fixed structure of this explosion-protection equipment can not adapt in light weight, the needs that cost is low of existing Aluminum cover battery.
Summary of the invention:
The explosion-protection equipment that the purpose of this invention is to provide the simple and a kind of lithium ion battery that cost is low of a kind of suitable aluminum cell housing battery anti-explosion requirement and technology.Technical solution of the present invention is, comprises cover plate and rupture pressure disc, it is characterized in that: the bottom surface that is located at the tubular rupture pressure disc in the big stepped hole of cover plate is relative with the aperture of cover plate, and the big step hole wall of an annular hold-down ring and tubular rupture pressure disc and cover plate is a tight fit.Described rupture pressure disc is Copper Foil or aluminium case.The present invention is fit to the explosion-proof and low remarkable advantage of the simple cost of technology of aluminum enclosure lithium battery compared with the prior art.
Description of drawings:
Fig. 1 is a front view of the present invention, and Fig. 2 is the A-A cutaway view of Fig. 1.
Embodiment:
The invention will be further described in conjunction with above accompanying drawing.After making rupture pressure disc and hold-down ring be contained in the cover board hole, can from the hole, not drop out, the big step hole wall of the outer tube wall of rupture pressure disc 2 and cover plate 1 matches, and the diameter of the outer wall of hold-down ring 3 should be greater than the inner diameter of rupture pressure disc, the rupture pressure disc tube inwall that makes hold-down ring be pressed into cover plate and Qi Nei becomes and closely cooperates, thereby the hold-down ring and the rupture pressure disc that are placed in the big stepped hole of cover plate can not dropped out from the hole.Below the big stepped hole of cover plate, be provided with aperture and compress annular distance and the rupture pressure disc bottom surface is relative.
Claims (2)
1. the explosion-protection equipment of a lithium ion battery comprises cover plate and rupture pressure disc, it is characterized in that: the bottom surface that is located at the tubular rupture pressure disc in the big stepped hole of cover plate is relative with the aperture of cover plate, and the big step hole wall of an annular hold-down ring and tubular rupture pressure disc and cover plate is a tight fit.
2. the explosion-protection equipment of a kind of lithium ion battery according to claim 1, it is characterized in that: described rupture pressure disc is Copper Foil or aluminium case.
