Abstract
The utility model discloses a lithium battery insulation upper gasket with high safety performance. The lithium battery insulation upper gasket is realized through the following technical proposal, and comprises an insulation upper gasket panel. The lithium battery insulation upper gasket is characterized in that a flexible rubber boss is fixed at two ends of the panel and hard rubber side walls are arranged on two sides of the middle part of the panel. Rubber materials are relatively flexible by nature and can be easily compressed, thereby reducing pressure on pole shoes and separators and improving the safety of the battery, and the rubber materials can absorb vibration energy and reduce damage to pole groups. The flexible rubber boss and the hard rubber boss ensure the safety of the battery.
Description
Technical field
The utility model relates to the lithium ion battery field, more particularly, relates to a kind of insulation Upper gasket of lithium ion square battery.
Background technology
Lithium ion battery because have high-energy-density, high working voltage, non-environmental-pollution, advantage such as have extended cycle life, and be widely used in portable communication apparatus and portable electric appts.The security performance of lithium ion battery is paid close attention to by people always, and wherein internal short-circuit is a key factor that influences cell safety, and the insulation Upper gasket plays an important role on the assurance battery security.
The utility model content
Technical problem to be solved in the utility model is, overcomes the deficiencies in the prior art, provides a kind of security performance high lithium-ion electric pool insulation Upper gasket.
The utility model lithium-ion electric pool insulation Upper gasket is achieved by following technical proposals, comprises insulation Upper gasket flat board, it is characterized in that described dull and stereotyped two ends are the soft rubber boss fixedly, and both sides, described dull and stereotyped middle part are provided with the vulcanie sidewall.
Insulation Upper gasket flat board described in the utility model is the soft rubber lamella.
The general employed material of insulation Upper gasket is generally the PP plastics now, it can prevent contacting of negative electrode lug and battery cap, and the effect that prevents utmost point group play in battery case, thereby guarantee the fail safe of battery, but the hardness of plastics is bigger, behind buckle closure pole piece and barrier film is had certain extruding, thereby can produce certain danger, the utility model insulation Upper gasket flat board is set to the soft rubber lamella, can alleviate above-mentioned extruding.Because elastomeric material itself is soft, easily be compressed, thereby alleviate pressure to pole piece and barrier film, improve the fail safe of battery, can absorb simultaneously the vibrational energy in the battery use, minimizing is to the damage of utmost point group, and the soft rubber boss of the utility model setting and soft rubber boss have guaranteed the fail safe of battery.
Description of drawings
Fig. 1 is the utility model cutaway view,
Fig. 2 is that the utility model uses schematic diagram.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further.
As shown in Figure 1, dull and stereotyped 11 two ends of insulation Upper gasket are soft rubber boss 12 fixedly, and both sides, described insulation Upper gasket flat board middle part are provided with vulcanie sidewall 13 respectively, and the Upper gasket that wherein insulate is dull and stereotyped to be the soft rubber lamella.Above-mentioned elastomeric material can adopt ethylene propylene diene rubber, butyl rubber etc.
As shown in Figure 2, battery case 1, battery cover 2, negative electrode lug 3, insulation Upper gasket 4, barrier film 5, pole piece 6.The sidewall of insulation Upper gasket adopts the rubber of hard, makes it can prevent contacting of negative electrode lug 3 and battery shell wall 1 effectively.The flat board and the boss of insulation Upper gasket adopt soft rubber, alleviate the pressure to barrier film 5 and pole piece 6, improve battery security.
Embodiment recited above is described the utility model preferred implementation; be not that design of the present utility model and scope are limited; under the prerequisite that does not break away from the utility model design philosophy; common engineers and technicians make the technical solution of the utility model in this area various distortion and improvement all should belong to protection range of the present utility model.
