In order to solve the problems of the technologies described above, a kind of column lithium ion battery provided by the utility model, comprise shell, positive pole cover plate and negative pole cover plate, described positive pole cover plate and described negative pole cover plate are tightly connected with the two ends of described shell respectively, it is characterized in that, described positive pole cover plate and described negative pole cover plate are respectively arranged with positive pole safety valve and negative pole safety valve.
Wherein in an embodiment, described positive pole safety valve comprises the safe valve opening of positive pole be arranged on described positive pole cover plate and the safe valve block of positive pole sealing the safe valve opening of described positive pole, and the safe valve block of described positive pole welds with described positive pole cover plate.
Wherein in an embodiment, the safe valve block of described positive pole is positive arch safety valve sheet.
Wherein in an embodiment, described positive pole safety valve sheet material is 3003 aluminium alloys.
Wherein in an embodiment, described negative pole safety valve comprise be arranged at the safe valve opening of negative pole on described negative pole cover plate and the safe valve opening of the described negative pole of sealing) the safe valve block of negative pole, the safe valve block of described negative pole welds with described negative pole cover plate.
Wherein in an embodiment, the safe valve block of described negative pole is the safe valve block of antiarch shape.
Wherein in an embodiment, described negative pole safety valve sheet material is 3003 aluminium alloys.
Compared with prior art, the column lithium ion battery that the utility model provides, respectively establishes a safety valve at positive and negative electrode, can effectively improve high capacity cell overcharging, cross the problem of putting, exploding in the situation such as high temperature, improve the security performance of battery, ensure personal safety.
The beneficial effect that the utility model additional technical feature has will be described in this specification embodiment part.

Description of reference numerals: 10, positive pole cover plate; 11, the safe valve opening of positive pole; 20, negative pole cover plate; 21, the safe valve opening of negative pole; 30, shell; 40, the safe valve block of positive pole; 50, the safe valve block of negative pole.
Embodiment
And the utility model is described in detail below with reference to the accompanying drawings in conjunction with the embodiments.It should be noted that, when not conflicting, the feature in following embodiment and embodiment can combine mutually.
As shown in Figure 1, 2, column lithium ion battery in one of them embodiment of the utility model comprises: shell 30, positive pole cover plate 10 and negative pole cover plate 20, described positive pole cover plate 10 and described negative pole cover plate 20 are tightly connected with the two ends of described shell 30 respectively, and described positive pole cover plate 10 and described negative pole cover plate 20 are respectively arranged with positive pole safety valve and negative pole safety valve.Described positive pole safety valve comprises the safe valve opening of positive pole 11 be arranged on described positive pole cover plate 10 and the safe valve block 40 of positive pole sealing the safe valve opening of described positive pole 11, and the safe valve block of described positive pole 40 welds with described positive pole cover plate 10.Described negative pole safety valve comprises the safe valve opening of negative pole 21 be arranged on described negative pole cover plate 20 and the safe valve block 50 of negative pole sealing the safe valve opening of described negative pole 21, and the safe valve block of described negative pole 50 welds with described negative pole cover plate 20.By respectively establishing a safety valve at positive and negative electrode, can effectively improve high capacity cell overcharging, cross the problem of putting, exploding in the situation such as high temperature, improve the security performance of battery, ensure personal safety.
As shown in Figure 3,4, the safe valve block of described positive pole 40 is positive arch safety valve sheet, and the safe valve block of described negative pole 50 is the safe valve block of antiarch shape.Because negative pole end gas production is more than positive terminal, the safe valve block of negative pole adopts antiarch shape safe valve block, and its pressure is high, opens rapidly, puts, can quick-opening safe valve in the situation such as short circuit when overcharging, crossing, and prevents battery explosion; And the safe valve block of positive pole adopts the simple positive arch safety valve sheet of structure, can be cost-saving.
The safe valve block of described positive pole 40 and described negative pole safe valve block 50 material are 3003 aluminium alloys, good welding performance, firm welding.
The above embodiment only have expressed several execution mode of the present utility model, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection range of the present utility model.
