The decomposition of the LiPF6 in electrolyte can be promoted, and form HF gases, cause cell internal pressure to become big, cell deformation, or even hair
Raw Decrepitation Phenomena；In addition, lithium battery capacity is decayed with the increase of moisture, excess moisture also results in the internal resistance of cell in lithium battery
Increase, when serious, electric discharge can not be charged normal by resulting even in lithium battery, it is impossible to storage of chemical energy.
Existing cylindrical lithium battery is using the blowout disk being arranged in block, to prevent lithium battery from deforming, when
When lithium battery interior pressure is excessive, gas pressure is on blowout disk so that the V-type portion on the blowout disk deforms, lithium
Internal cell volume increases, and air pressure reduces；In addition, in order to control the moisture in lithium battery, lithium battery is complete in drying shed
Into production.But, the effect that existing cylindrical lithium battery completely cuts off moisture under conventional use environment is not good, although using safety diaphragm
Piece prevents cell deformation and explosion, but outside moisture still is able to enter lithium battery interior, causes lithium battery capacity reduction, internal resistance
Increase.
The current packaging technology of cylindrical battery is usually to carry out slot rolling and machinery sealing using PP sealing rings to be sealed, compared with
The cylinder-type power battery of major diameter also completes the sealing of battery in addition to using above method using the method for laser welding
It is close when the electrokinetic cell of major diameter is sealed using PP sealing rings first in place of technique, but the equal Shortcomings of both approaches
Seal effect poor, and the phenomenon of leakage can be produced during high-low temperature resistant cyclic test.Secondly carried out sealedly, first using laser welding
Increase equipment investment, to buy high power CW laser welder, and by welding equipment and can be welded unavoidably in welding
The material influence connect, causes rosin joint or trachoma, once welding causes to be difficult to after defect, battery liquid-filling by Welding Repair, because
This is necessary to propose a kind of cylindrical battery sealing structure of safety low cost.
