Description
Technical field
The utility model belongs to lithium-ion-power cell, is specifically related to a kind of battery-operated motor cycle that is applied to, the uncharged high-power lithium ion electrokinetic cell of the box hat housing of vehicle using motor and automobile.
Background technology
The most lead-acid batteries that adopt of present battery-operated motor cycle and vehicle using motor are as electrical source of power, automobile start also to adopt lead-acid battery, problems such as lead-acid battery ubiquity specific energy is low, cycle life is short, and in battery is scrapped, also can produce than serious environmental and pollute.These are all limiting the electric motor car of increase day by day and the development of automobile market.Lithium ion battery specific energy height, and have extended cycle life, environmental pollution is little, belongs to green energy resource, so lithium ion battery adapts to market demands, develop rapidly.But traditional box hat high-power lithium ion electrokinetic cell, its outer casing electrification is negative pole, in the process that moves, is easy to contact with anodal, causes short circuit; And the short circuit meeting causes bigger influence to battery, and the little battery moment no-voltage that then makes greatly then causes battery explosion.
Summary of the invention
The purpose of this utility model be to overcome the deficiencies in the prior art and provide a kind of simple in structure, have extended cycle life, thereby specific energy is high and the not charged uncharged high-power lithium ion electrokinetic cell of box hat housing that makes the lithium ion battery stable performance of battery container.
The purpose of this utility model is achieved in that and comprises positive pole and negative pole, and positive pole is welded in the anode collection circle, and the anode collection circle is connected with the explosion-proof assembly of loam cake by the anodal aluminium strip that connects, and the explosion-proof assembly of Positive Poles and loam cake passes through bolt; Negative pole is welded in the negative pole currect collecting circle, and the negative pole currect collecting circle directly links to each other with the negative pole pole, is provided with insulation spacer between negative pole currect collecting circle and box hat housing, and the negative pole pole passes insulation spacer and box hat housing, and electric core is cylindrical monomer electricity core; Between described negative pole pole and the box hat housing fluid sealant is arranged, described negative pole pole does not link to each other with the box hat housing.Described electric core comprises positive plate and negative plate, and anodal uncoated extension is arranged on the positive plate, and the uncoated extension of described positive pole is an anode ear, and the uncoated extension of negative pole is arranged on the negative plate, and the uncoated extension of described negative pole is a negative electrode lug.Be provided with positive electrical core pad between described electric core and the anode collection circle; Be provided with negative electricity core pad between described electric core and the negative pole currect collecting circle.
The utlity model has following advantage:
1, the utility model simple in structure, have extended cycle life the specific energy height.
2, negative pole currect collecting circle of the present utility model does not directly link to each other with box hat, but directly link to each other with the negative pole pole, between negative pole currect collecting circle and battery container, insulation spacer is arranged, with fluid sealant negative pole pole and battery container are separated equally in the battery case outside, make the battery steel shell housing not charged, thereby guarantee that battery is difficult for causing short circuit in moving process, help the safety of battery performance.
