Abstract
The utility model discloses a cylinder lithium-ion battery cover seal ring for improving the battery cover sealability of the cylinder lithium-ion battery. The cylinder lithium-ion battery cover seal ring of the utility model is characterized in that the sealed ring periphery is provided with a sealant coating. Because the utility model sets up a sealant coating on the battery cover seal ring, the battery sealability is improved, the battery can endure more internal pressure without leakage, and further the safety is improved.
Description
Technical field
The present invention relates to the cell sealing apparatus field, more particularly, relate to a kind of cylindrical lithium ion battery battery cover joint.
Background technology
At present, lithium ion battery is advantage such as high and in light weight because of environmental protection, specific energy, and range of application is more and more widely almost all used the energy type lithium ion battery on notebook computer, in the existing trend that replaces NI-G and ni-mh of field of power tools comprehensively.Along with the development of technology and the raising of customer demand, battery sealing-performance also becomes the important indicator of estimating battery quality.
The utility model content
Technical problem to be solved in the utility model is that a kind of cylindrical lithium ion battery battery cover joint that improves cylindrical lithium ion battery battery cover sealing is provided.
The utility model cylindrical lithium ion battery battery cover joint is characterized in that, described sealing ring outer peripheral face is provided with the fluid sealant coating.
The utility model fluid sealant kind is not limit, as long as can play sealing function, but can not react with the battery electrolyte inside.The fluid sealant material is dissolved in organic solvent by raw materials such as polyisobutene, rubber, pitches and constitutes.
The beneficial effects of the utility model are:
1, because of adopting battery cover joint that the fluid sealant coating is set, the sealing of battery has been strengthened, battery can bear bigger internal pressure and not leak, and has improved the sealing of battery, has further improved fail safe.
2, because of adopting battery cover joint that the fluid sealant coating is set, the problem of battery sepage when falling, overcharging test is improved.
3, because of adopting battery cover joint that the fluid sealant coating is set, reduced because of the battery sepage by the risk of customer complaint.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
Details are as follows to the utility model below in conjunction with accompanying drawing:
As shown in Figure 1, the utility model cylindrical lithium ion battery battery cover joint 1 outer peripheral face is provided with fluid sealant coating 2.Whole sealing ring border all is provided with the fluid sealant coating to reach the effect of sealing.
The fluid sealant kind is not limit, as long as can play sealing function, but can not react with the battery electrolyte inside.The utility model fluid sealant material is dissolved in organic solvent by raw materials such as polyisobutene, rubber, pitches and constitutes.
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.
Claims (2)
