Description

A kind of battery formation clamp of lithium ion battery
Technical field
The utility model relates to a kind of aid producing lithium ion battery, especially to a kind of battery formation clamp of lithium ion battery.
Background technology
Changing into is the very crucial together operation of rechargeable battery, lithium ion battery is rechargeable battery, so the index such as the cycle life of craft method to lithium battery, storge quality, capacity performance, security performance that lithium ion battery changes into work step plays important effect.Principle briefly, is exactly to battery first time charging, allows the active material in battery activate, generating a kind of film of densification, so as to protecting whole chemical interface simultaneously at anode surface.The Normal practice that lithium ion battery changes into directly battery is connected charging cabinet, just carries out small area analysis at normal temperatures change into without additional especially fixture.This way technique is simple, easy to operate, not high to equipment requirement, by most factory is adopted.Although this kind of method is simple, change in the absence of stress, the general forming current adopted is between 0.1-0.3CmA, and the time needs 5-10 hour, production efficiency and utilization rate of equipment and installations lower; In addition in the method the evenness of battery and hardness lower, during formation charging, lithium ion pole piece in transfer process there will be concentration polarization, CURRENT DISTRIBUTION is uneven, the blind spot do not reacted is had to exist, impurity composition can be caused to decompose thorough, all have harmful effect to the capacity performance of battery and the cycle life of battery.
Summary of the invention
The purpose of this utility model overcomes the pole piece concentration polarization existed in lithium ion battery formation process in prior art, the problem that formation effect is poor, production efficiency is low, provides that a kind of structure is simple, easy to use, formation effect is good, can enhance productivity and the battery formation clamp of lithium ion battery of utilization rate of equipment and installations.
For realizing above object, technical solution of the present utility model is: a kind of battery formation clamp of lithium ion battery, comprise battery, it is characterized in that: also comprise from top to bottom horizontal four pieces of clamping plate successively, be respectively a plate, No. two plates, No. three plates and No. four plates, screw rod is fixedly linked through a plate and No. two plates, and battery is placed and on No. three plates, is provided with spring between No. three plates and No. four plates.
A described plate is vertical with between No. four plates is connected with guide rod, and guide rod is through No. two plates and No. three plates.
Described clamping plate are steel plate, and thickness is more than 12 millimeters.
The loading of described spring is more than 15 kilograms.
Described screw rod through Overheating Treatment, external diameter more than 12 millimeters.
The beneficial effects of the utility model are:
1, clamping plate, screw rod and spring is utilized to apply larger pressure to change into battery in the design, effectively improve evenness and the hardness of battery, positive/negative plate close contact when can realize changing into, effectively can solve the concentration polarization in lithium ion transfer process, homogeneous current distribution, the impurity of inside battery thoroughly decomposes, and be improved to the storge quality of battery and life-span, formation effect is good.
2, employ clamping plate and spring in the design, be applied with certain pressure when changing into battery, forming current can be increased to 0.3-0.6CmA, and the time of changing into can complete in 0.5-2 hour, substantially increased production efficiency and utilization rate of equipment and installations.
3, in the design, plate is vertical with between No. four plates is connected with guide rod, and guide rod is through No. two plates and No. three plates, and guide rod plays guide effect, and pressure energy is evenly distributed on battery.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: battery 1, clamping plate 2, a plate 21, No. two plates 22, No. three plates 23, No. four plates 24, screw rod 3, spring 4, guide rod 5.
Embodiment
Illustrate below in conjunction with accompanying drawing and with embodiment, the utility model to be described in further detail:
See Fig. 1, a kind of battery formation clamp of lithium ion battery, comprise battery 1, it is characterized in that: also comprise from top to bottom horizontal four pieces of clamping plate 2 successively, be respectively a plate 21, No. two plates 22, No. three plates 23 and No. four plates 24, screw rod 3 is fixedly linked through a plate 21 and No. two plates 22, and battery 1 is placed and on No. three plates 23, is provided with spring 4 between No. three plates 23 and No. four plates 24.
A described plate 21 is vertical with between No. four plates 24 is connected with guide rod 5, and guide rod 5 is through No. two plates 22 and No. three plates 23.
Described clamping plate 2 are steel plate, and thickness is more than 12 millimeters.
The loading of described spring 4 is more than 15 kilograms.
Described screw rod 3 through Overheating Treatment, external diameter more than 12 millimeters.
Clamping plate 2, screw rod 3 and spring 4 pairs of batteries 1 are utilized to apply larger pressure to change in the design, effectively improve evenness and the hardness of battery 1, positive/negative plate close contact when can realize changing into, effectively can solve the concentration polarization in lithium ion transfer process, homogeneous current distribution, the impurity of inside battery thoroughly decomposes, and be improved to the storge quality of battery 1 and life-span, formation effect is good.Employ clamping plate 2 and spring 4 in the design, be applied with certain pressure when changing into battery 1, forming current can be increased to 0.3-0.6CmA, and the time of changing into can complete in 0.5-2 hour, substantially increased production efficiency and utilization rate of equipment and installations.In the design, plate 21 is vertical with between No. four plates 24 is connected with guide rod 5, guide rod 5 is through No. two plates 22 and No. three plates 23, guide rod 5 plays guide effect, and play the effect fixing a plate 21 and No. four plates 24, and under the active force of screw rod 3, No. two plates 22 and No. three plates 23 and battery 1 can be moved, the active force of spring 4 can be evenly distributed on battery 1.
The present invention adopts a device compressed with spring 4, apply certain external force to the battery 1 that will change into compress, and then the positive and negative lug that battery 1 exposes is connected to forming and capacity dividing cashier's office in a shop changes into, clamping plate 2 will have enough intensity, could not deform under impressed pressure, more than 12 millimeters thick steel plates generally will be had just to meet the demands; The pressure of spring 4 will meet certain requirement, and loading, more than 15 kilograms, guarantees there is enough pressure to battery; Whole fixture adopts screw rod 3 to rotate and can apply and pressure relief top board, require that screw rod 3 external diameter is more than 12 millimeters, through Overheating Treatment, to ensure abrasion resistance.The utility model structure is simple, easy to use, formation effect is good, can enhance productivity and utilization rate of equipment and installations.
