With lithium ion battery continue to develop and application field developing, requirement more and more higher of the heavy-current discharge field to battery.
Cylindrical steel shell battery, soft-package battery, square aluminum-shell battery etc. are divided into according to contour structures difference.Wherein cylindrical battery is commonly positive and negative
Pole insulation spacer only plays insulating effect, battery service life middle and later periods due to the consumption of electrolyte, cycle life decay
Comparatively fast.Used as Vehicular battery, can also be often subject to vibration environment effect.Therefore in order to improve environmental suitability and electrolyte
Consumption problem needs to be improved on battery structure.
The content of the invention
The present invention provides a kind of with the cylindrical lithium ion battery for protecting liquid and vibration proof structure, solves guarantor's liquid of cylindrical lithium battery
And vibration problems.
To achieve the above object, the technical solution adopted in the utility model is：
Volume is spaced apart with the cylindrical lithium ion battery for protecting liquid and vibration proof structure, including positive plate, barrier film and negative plate
The battery core being coiled into, battery core is arranged in cylindrical steel shell, and battery core is set and the gap between box hat is full of electrolyte, and the battery core exists
Top and bottom in box hat are respectively equipped with porous insulation pad, and the center of porous insulation pad is provided with centre bore.
Wherein the porosity of porous insulation pad is 40 ~ 80%.
Porous insulation pad material is porous shaped polyethylene, polypropylene, polyphenylene sulfide or polyethylene terephthalate
One kind in resin.Porous insulation pad material is porous shaped polyethylene.
Electrolyte is the organic solution of lithium hexafluoro phosphate.The positive terminal of box hat is provided with cap sealed, porous insulation pad
One round sides form curved surface and are contacted with box hat inner tight after setting removal part with the edge rib of side face cohesive position.
Advantageous Effects of the present utility model are：
1st, porous insulation pad plays imbibition, protects liquid effect, can be discharged after electrolyte consumption occurs in lithium battery interior
Electrolyte in felt pad hole, can effectively alleviate the loss problem of lithium ion battery electrolyte in cyclic process.Effectively
The battery of raising is service life cycle.
2nd, the porous insulation pad elastic and porous insulation pad certain because its loose structure has is at the two ends of battery core

Specific embodiment
The utility model as shown in figure 1, with the cylindrical lithium ion battery for protecting liquid and vibration proof structure, including positive plate 4, every
Film 5 and negative plate 6 are spaced apart the battery core being wound into, and battery core is arranged in cylindrical steel shell 1, and the gap between battery core and box hat is filled
Full electrolyte 7, top and bottom of the battery core in box hat 1 are respectively equipped with porous insulation pad 3, porous insulation pad 3
Center is provided with centre bore 8.
The porosity of porous insulation pad 3 is 40 ~ 80%.The material of porous insulation pad 3 be porous shaped polyethylene, polypropylene,
One kind in polyphenylene sulfide or pet resin.
The material of porous insulation pad 3 is porous shaped polyethylene.Electrolyte 7 is the organic solution of lithium hexafluoro phosphate, and porous
Insulation spacer 3 does not react..
The positive terminal of box hat 1 is provided with block 2 and seals.One round sides of porous insulation pad 3 and side face cohesive position
Formation curved surface 9 is contacted with box hat inner tight after edge rib sets removal part.
The loose structure more than enough 0.7 ~ 1g of Electolyte-absorptive of energy in porous insulation pad, and store in the porous of felt pad
In, when consumption occurs in electrolyte of the battery in cyclic process, the electrolyte in porous insulation pad can enter battery core and box hat
Between space in, supplement the amount of electrolyte, by the electrolyte retained porous insulation pad, the electric discharge of lithium battery being improved more
Number of times, contributes to the raising of cycle performance.The cycle life of battery is brought up to 2500 times by 2000 times.
Porous felt pad has preferable elasticity in itself, when battery core occurs shaking in inside battery, porous insulation pad
The vibrations of battery core can be buffered, the vibrations potential energy of battery core is absorbed, it is to avoid great amplitude causes battery core to be damaged.
