Description

A kind of battery pole piece infuser device

Technical field

The utility model relates to cell manufacturing techniques fields, and in particular to a kind of battery pole piece infuser device.

Background technique

With the development of new energy technology, battery using more and more extensive, wherein the most universal with lithium ion battery.Lithium Ion battery needs pole piece impregnating electrolyte in the production process, and for common batteries or large-sized battery, pole piece is past First impregnated toward being, then cut in flakes, the lithium as disclosed in the Chinese utility model that Authorization Notice No. is CN204966620U from Sub- battery pole piece mends lithium device, which is brought into the pole piece of the winding on let off roll in electrolytic bath by reversing roller and is carried out It impregnates, but for minicell, such as button cell, generally only drips upper electrolyte on pole piece in the pre-assembly.? 12-15 hours are stood after the assembly is completed so that internal fluid injection is sufficiently infiltrated with pole piece.But due to button cell reservoir quantity is less, Assembling pressure is larger, though room temperature stand after, in electrolyte and pole piece infiltrate still be not enough.Therefore, existing to have In such a way that the pole piece of button type battery in the pre-assembly impregnate to improve effect of impregnation, shorten time of repose, but It is a kind of existing not very applicable infuser device.

Utility model content

The purpose of this utility model is to provide a kind of structure is simple, battery pole piece infuser device easy to use.

The battery pole piece infuser device of the utility model includes opening up box body, is equipped in box body multiple opening up Soaking compartment, soaking compartment is vertically extending and pole piece is enable vertically to place.Using the utility model infuser device when, will cut out Good pole piece is vertically placed in slot, and electrolyte is perfused into slot and is impregnated, and after immersion, takes out pole piece.

Further, soaking compartment is arranged in matrix form and at least a row or column soaking compartment is interconnected.It is convenient in this way Electrolyte is perfused into same a line or same row.

Further, two adjacent in same row soaking compartment pass through the notch connection being arranged on the cell wall being separated by, and same One column soaking compartment can guarantee that the electrolyte in each soaking compartment of same row quickly fills by the S-shaped connection of notch in this way It is full.

Further, each column soaking compartment is interconnected, adjacent two column soaking compartment pass through between partition on be arranged it is logical Realize connection in hole.

The infuser device further includes box cover of the spiral-lock on box body, and box cover can guarantee to avoid falling into soaking process dirty Object.

When forming soaking compartment, the partition arranged in length and breadth can be set in the bottom surface of box cavity, the partition constitutes each The cell wall of a soaking compartment.

The sidewall upper face of the box body is high outside and low outside inclined-plane, and the marginal position of the downside of box cover has and box body The inclined surface of inclined-plane cooperation on sidewall upper face.Make that placement can be stablized when box cover is fastened on box body in this way.

The upper top surface of partition is lower than the side wall of box body.It can either guarantee that pole piece is in box body in this way, guarantee sealing, again Part pole piece can be made to expose soaking compartment, convenient for taking out pole piece from soaking compartment.

Further, the side wall of box body is equipped with the gap for pouring out electrolyte, convenient for toppling over for electrolyte.It is more square Just, the corner that adjacent two sidewalls connect can be arranged in the gap.

Specific embodiment

The embodiments of the present invention is described further with reference to the accompanying drawing.

The specific embodiment of the battery pole piece infuser device of the utility model, as shown in Figure 1 to Figure 3, including it is opening up Box body 1, multiple soaking compartments 11 are equipped in box body 1, soaking compartment 11 is vertically arranged and battery pole piece can be made vertically to be placed on slot It is interior, more pole pieces can be impregnated in the box body of certain volume in this way.Since the infuser device is suitable for button cell mostly The pole piece diameter of the immersion of pole piece, button cell is φ 12mm, and with a thickness of 60 μm, therefore, the depth of each soaking compartment 11 can be 10mm, i.e., slightly below the height of pole piece and expose the upper part of pole piece, length can be 15mm, width can be 3mm.When So, if when the pole piece to conventional lithium-ion battery or large-sized battery impregnates, the volume of soaking compartment can be changed therewith.

The intracavity bottom of box body 1 is equipped with the partition of transverse and longitudinal setting, and partition constitutes the cell wall of soaking compartment 11 and surrounds each leaching Slot is steeped, the partition of transverse and longitudinal setting arranges that soaking compartment in matrix form, wherein each column soaking compartment is interconnected.It is once soaking in this way The pole piece quantity of bubble be not more than a column soaking compartment slot number when, can only in a column soaking compartment be perfused electrolyte, using compared with It is flexible.

In the present embodiment, the soaking compartment of same row is by the lateral partitions 12 that are arranged between two neighboring soaking compartment Notch 13 realize connection, notch 13 is staggeredly located in two adjacent lateral partitions 12 in the soaking compartment of same row, whole Make same row soaking compartment by the S-shaped connection of notch on body, which can be clear that from Fig. 2, in this way can be Make the S-shaped flowing of electrolyte when electrolyte being perfused into same row soaking compartment, can quickly make the electrolysis in each soaking compartment Liquid filling is uniform.

It is separated between the soaking compartment of adjacent two column by same longitudinal baffle 15, certainly in other embodiments, such as together When the soaking compartment of a line is connected, notch or through-hole can be set in the longitudinal baffle 15；Or all soaking compartments are when being all connected to, Notch or through-hole are respectively set in lateral partitions and longitudinal baffle.

In addition, the infuser device further includes box cover 2, box cover 2 is buckled in cassette upper end opening, can be in pole piece soaking process Middle guarantee box body sealing.Preferably, the sidewall upper face of box body 1 can be set to high outside and low outside inclined-plane, the downside of box cover 2 Marginal position have on 1 sidewall upper face of box body inclined-plane cooperation inclined surface.Make to be fastened on box body in box cover in this way It is more stable when upper.

The side wall of box body 1 is equipped with the gap 14 for pouring out electrolyte, it is, of course, preferable to ground, gap 14 is arranged adjacent The corner that two sidewalls connect is convenient for toppling over the electrolyte in soaking compartment in this way.

Certainly, the battery pole piece infuser device of the utility model is not limited in above-described embodiment, in other embodiments In, the intracavity bottom of box body can be arranged in grid, and each grid constitutes soaking compartment, and the lattice wall for constituting grid connects equipped with through-hole Lead to each soaking compartment；Downward surrounding edge can be set in the outer edge of box cover, and the area that the four sides surrounding edge of box cover is enclosed is equal to box body Top surface area, box cover are buckled on box body and are surrounded the four sides side wall of box body by four sides surrounding edge.The shape of box body simultaneously not only limits In rectangular, or round or oval or other polygons.
