Abstract
The utility model discloses a kind of safety anti-explosive structure of power lithium-ion battery, comprise square housing, it is characterized in that: described housing is provided with several openings, described opening is sealed by explosion-proof aluminium plastic film, and the junction of described explosion-proof aluminium plastic film and housing is provided with plastic material sealant; The width of described sealant is 2 ~ 3mm; Described plastic material is PP glue.The utility model has following beneficial effect: have structure simple, workable, on housing, be provided with opening and use explosion-proof aluminium plastic film to seal opening, make battery when bulge, improve the fail safe of box hat or aluminum-shell battery.
Description
Technical field
The utility model relates to a kind of lithium ion battery, is specifically related to a kind of safety anti-explosive structure of power lithium-ion battery.
Background technology
Lithium ion battery belongs to rechargeable pond, have that operating voltage is high, energy density is high, serviceability temperature wide ranges, have extended cycle life, the outstanding advantages such as self discharge coefficient is little, environmental protection.Be widely used in various mobile digital product, electric tool, electronic toy, notebook computer, electric motor car etc., and in the very large market share of secondary cell market share.
Lithium ion battery, according to external shape, can be divided into square, column type, is divided into box hat, aluminum hull, aluminum plastic film according to housing material.At present, lithium ion battery mainly contains several external structure modes such as square box hat, shell with square aluminum, box hat column type and aluminum plastic film Soft Roll.
And the rectangular lithium ion battery of box hat conventional at present or aluminum hull, because its shell material is relatively hard, battery produces abnormal battery flatulence in production or use procedure, has the danger producing blast during bulge.
Utility model content
Technical problem to be solved in the utility model is to provide the safety anti-explosive structure of a kind of power lithium-ion battery that structure simply, is conveniently produced, security performance is high.
The technical solution realizing the utility model object is: a kind of safety anti-explosive structure of power lithium-ion battery, comprise square housing, it is characterized in that: described housing is provided with several openings, described opening is sealed by explosion-proof aluminium plastic film, and the junction of described explosion-proof aluminium plastic film and housing is provided with plastic material sealant.
The width of described sealant is 2 ~ 3mm.
Described plastic material is PP glue.
The safety anti-explosive structure of a kind of power lithium-ion battery of the utility model has following beneficial effect: have structure simple, workable, on housing, be provided with opening and use explosion-proof aluminium plastic film to seal opening, make battery when bulge, improve the fail safe of box hat or aluminum-shell battery.
Accompanying drawing explanation
Below in conjunction with accompanying drawing and embodiment, the utility model is elaborated;
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation that the utility model removes explosion-proof aluminium plastic film.
Embodiment
As shown in Figure 1 and Figure 2, a kind of safety anti-explosive structure of power lithium-ion battery, comprise housing 1 and cap 2, described cap 2 sealing is assemblied in housing 1 end, described housing 1 is in square, described housing 1 is steel sheel or aluminum enclosure, cap 2 is drawn positive terminal 3 and negative terminal 4, described housing 1 is provided with several openings 5, described opening 5 is sealed by explosion-proof aluminium plastic film 6, described explosion-proof aluminium plastic film 6 is provided with plastic material sealant 7 with the junction of housing 1, and the hot pressing of described explosion-proof aluminium plastic film 6 is fitted on plastic material sealant 7, ensures the sealing of housing.The width of described sealant 7 is 2 ~ 3mm, and described plastic material is PP.
Housing is provided with opening and uses explosion-proof aluminium plastic film to seal opening, and battery, when bulge, when the pressure of housing reaches certain level, is first burst explosion-proof aluminium plastic film, immediately release, then significantly improve the fail safe of the battery that steel sheel and aluminum enclosure are made.
