Description
Technical field
The utility model relates to a kind of storage battery, particularly a kind of new type lithium ion storage battery.
Background technology
Lithium-ions battery has safety, and stability is high, and specific energy is big, memory-less effect, advantages such as quickly-chargeable has extended cycle life, and is pollution-free, be widely used in large-scale and the light-weight electric vehicle, the light-weight electric instrument, the energy storage device of solar energy and wind power generation, aspects such as mobile communication equipment, therefore more and more higher to the performance and the structural requirement of lithium ion battery, be the main direction of current battery circle research and development.
Before the present utility model, the pole quantity of lithium-ions battery generally is one of positive terminal, one of negative terminal, because lithium-ions battery is widely used on the large-scale and light-duty motor vehicle, and vehicle vibrations in the process of moving, quicken or deceleration suddenly, cause the loosening of pole and brace when perhaps colliding easily, even fracture, because of the loose contact meeting causes the battery sparking, because of the pole fracture can cause opening circuit of battery, so all can work the mischief, because the existence of this defective causes us to have certain potential safety hazard in the process of using lithium ion power storage battery to people and vehicle.
Summary of the invention
The purpose of this utility model will overcome above-mentioned defective exactly, design, a kind of new type lithium ion storage battery of development.
The technical solution of the utility model is:
A kind of new type lithium ion storage battery, include battery battery core, its major technique is characterised in that the top of described battery battery core is fixedly connected with pole assembly system, described pole assembly system is furnished with bipolar post, described bipolar post is meant that a pair of positive terminal is fixed together, a pair of negative terminal is fixed together, described positive terminal, negative terminal all is arranged on the aluminium cover plate, positive terminal, last insulation spacer is arranged at top between negative terminal and the aluminium cover plate, metallic gasket, positive terminal, insulation spacer is arranged at the bottom between negative terminal and the aluminium cover plate, insulation board, the negative pole bolt connects negative terminal, insulation board, insulation spacer, aluminium cover plate, last insulation spacer and metallic gasket, positive pole bolt connects positive terminal, insulation board, insulation spacer, aluminium cover plate, last insulation spacer and metallic gasket.
Advantage of the present utility model is to make battery electrode column more reliable with contacting of brace with effect, thereby has guaranteed the serviceability of lithium-ions battery, impels the fail safe of lithium-ions battery that further lifting is arranged, and is of great practical significance.
Other advantages of the present utility model and effect will go on to say below.

Embodiment
As shown in Figure 1, Figure 2, Figure 3 and Figure 4:
The utility model includes battery battery core 1, and the welded top of battery battery core 1 has pole assembly system 2; Pole assembly system 2 is furnished with a pair of positive terminal 3 and a pair of negative terminal 7, a pair of positive terminal 3 closely connects, positive terminal 3 bottoms and electric in-core portion positive plate (do not draw among the figure, omit) be connected, a pair of negative terminal 7 closely connects, negative terminal 7 bottoms and electric in-core portion's negative plate (do not draw among the figure, omit) are connected; Positive terminal 3 and negative terminal 7 are arranged on the aluminium cover plate 6, and top has last insulation spacer 11, metallic gasket 8 to do the insulation protection between positive terminal 3 and negative terminal 7 and the aluminium cover plate 6; The bottom has insulation spacer 5, insulation board 4 to do the insulation protection between positive terminal 3 and negative terminal 7 and the aluminium cover plate 6; Positive terminal 3, insulation board 4, insulation spacer 5, aluminium cover plate 6, last insulation spacer 11 and metallic gasket 8 are connected by positive pole bolt 10, negative terminal 7, insulation board 4, insulation spacer 5, aluminium cover plate 6, last insulation spacer 11 and metallic gasket 8 are connected by negative pole bolt 9, all there is tapped blind hole at positive pole bolt 10, negative pole bolt 9 centers, be connected with external brace (do not draw among the figure, omit).
The explanation of the utility model application process:
Flow when electric current flows to negative pole by positive pole, because a pair of positive terminal 3 and a pair of negative terminal 7 are arranged, even a positive terminal 3 therefore occurs or negative terminal 7 is loosening, another positive terminal 3 or negative terminal 7 are still fastening, thereby avoid going wrong.Particularly,, can produce spark between positive terminal 3 and the negative terminal 7 if become flexible as in the colliery, may explosion caused or fire.
In the concrete practice, the utility model has been cancelled the structure of one pole post in pole assembly system, and adopts bipolar post, promptly a pair of positive terminal 3 and a pair of negative terminal 7, and it is little that so bipolar post has internal resistance, conducts electricity very well antidetonation, anti-loosening characteristics.Positive terminal 3 has two binding posts, and negative terminal 7 also has two binding posts, even it is solid and reliable that connection is stablized; The structure of bipolar post can be guaranteed the rotation that positive terminal 3, negative terminal 7 can be not random simultaneously, thereby has guaranteed the reliable and safety of battery more.
The technical scheme that is provided by above the utility model as seen, make the fail safe of lithium-ions battery that further raising arranged, strengthened the antidetonation of lithium-ions battery, impact resistance and anti-drop, help the safe extensive use of lithium-ions battery, be of great practical significance.
In addition, the utility model is convenient for production, reliable, and technology is simple, and the efficient height.
In sum, compared with prior art, the lithium-ions battery that the utility model provides can be that pole is more solid and reliable with linking of brace, thereby guarantee the safe handling of battery, is of great practical significance.
The above only is an optimal way of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection range of the present utility model.
