Description
Technical field
This utility model belongs to polymer Li-ion battery manufacturing technology field, particularly relates to a kind of Wind lithium ion
Core.
Background technology
In order to cater to people's pursuit more diversified to shape of product, communication, the profile of digital product the most no longer stick to
The profile of existing Founder, and occur in that more shape.Sometimes for the profile of adaptation product, for depositing the space of battery also
It is not necessarily such as the hexahedral shape such as cuboid or square, it is also possible to there is the polyhedron of spill.For special shape
For battery storing space, if still using common rectangle battery core, the most regular rectangle battery core cannot make full use of reserved
Depositing the space of battery core, cause battery core design capacity low, the device standby time is short.
Utility model content
The purpose of this utility model is to provide a kind of equipment reserved battery storing slot space utilization rate of can improving
Takeup type spill battery core.
To achieve these goals, this utility model takes following technical solution:
A kind of spill battery core, including stacking gradually the anode pole piece of placement, barrier film and cathode pole piece, described anode pole piece,
The coiled material that barrier film and cathode pole piece are formed winds formation core continuously；Have multiple along pole on described anode pole piece and cathode pole piece
The spaced grooving of length direction of sheet, the aligned in position of the grooving on each circle pole piece.
Further, described grooving is arranged along the edge of pole piece.
Further, it is spaced apart L between described n-th grooving and its previous groovingn=L0+ (n-2) × l, n >=2.
From above technical scheme, this utility model cuts out multiple grooving by the length set on pole piece, at volume
Around time make the grooving on each circle pole piece align, the grooving that overlaps forms the recess in core, thus prepares spill
Battery core, the battery core being coincide with battery core parking space shape by preparation, is improved parking space utilization rate, thus improves equipment
Battery core capacity and device standby time, solve because being limited the device standby time caused short problem by battery capacity.

Detailed description of the invention
In order to above and other purpose of the present utility model, feature and advantage can be become apparent from, cited below particularly practicality is new
Type embodiment, and coordinate appended diagram, it is described below in detail.
The purpose of this utility model is to provide a kind of spill battery core, the concave structure of this battery core at least one end, such as electricity
Core arranges the concave structure in end or the end relative with lug or this both ends of lug, in order to can better adapt to set
Standby reserved battery storing space, improves the design capacity of battery core.
The preparation method of spill battery core of the present utility model is as follows:
Common process is used to prepare pole piece: to make anode pole piece soldering polar ear at plus plate current-collecting body overlying active substance,
Negative current collector coats active substance and makes cathode pole piece soldering polar ear；
Line on the basis of painting line (being i.e. coated with the initiating terminal sideline in active substance region) is played, along pole piece by the painting cream of pole piece
Length direction interval initial cut distance L1Cut out first grooving a, then at interval of a cutting gap length Ln, just exist
Cut out an identical grooving a of size on pole piece, thus obtain the pole piece (Fig. 1) with multiple grooving a spaced apart；This
The grooving of embodiment is positioned at a limit at the edge of pole piece, i.e. grooving and overlaps with the long limit of pole piece, is thus formed at pole piece edge
Multiple groovings；Cut cutting gap length L during the n-th groovingn=L0+ (n-2) × l, n >=2, wherein, L0Between cutting for standard
Every length, the length increment of each circle (folding) pole piece circle (folding) pole piece the most thereon when l is winding, such as the 2nd circle pole piece
The length value that relative 1st circle pole piece increases, initial cut gap length L1, standard cutting gap length L0, grooving a size with
And the length increment l of each circle pole piece is that the size of the size according to battery and parking space is configured；Can use sharp
Light cutting or alternate manner carry out grooving, when the residue length of pole piece is less than LnTime stop cutting；Cut cutting during the 2nd grooving
Gap length L2=L0, the cutting gap length L of the present embodimentnFor the distance between adjacent two grooving geometric centers, but between cutting
Can also be the spacing between two groovings every length；
Anode pole piece, barrier film, cathode pole piece stack formation coiled material successively be wound, during winding on each circle pole piece
Grooving aligned in position, the grooving on the most each circle pole piece overlaps, thus can make the concave shape of core (Fig. 2)；
Barrier film is punched out, uses common process to press the shape molding putamina of battery core, and it is packaged, the most right
Aluminum plastic film unnecessary in groove is punched out, thus prepares spill finished product battery core (Fig. 3).
Spill battery of the present utility model contrasts with existing rectangle battery core, may be used for the equipment of particular design structure
In, thus improve the space availability ratio of device battery groove, the beneficially battery core capacity of raising equipment and the raising device standby time.
As an optimal technical scheme of the present utility model, the step making pole piece is as follows:
The white space of soldering polar ear is remained for the most in advance when coating active substance (painting cream) on a current collector, but at afflux
Coat active substance in the whole region of body, make active substance that pole piece is completely covered, such that it is able to improve the flatness on battery core surface
With battery core energy density, thus improve the cycle performance of battery core；Then the activity in soldering polar ear region on collector is disposed
Material, finally at this region soldering polar ear, and rubberizing protection.It is furthermore preferred that use the mode of laser cleaning to remove soldering polar ear
The active substance in region but it also may use the alternate manner such as vacuum removing or rubberizing removing to remove the work in soldering polar ear region
Property material.In the present embodiment, the position of soldering polar ear is at the head of pole piece, but the position of soldering polar ear can also be in pole piece
Portion or afterbody.
The battery core groove formed by the grooving of multiple overlaps may be located in the middle of two lugs of battery core, it is also possible to is positioned at the two poles of the earth
The side of ear, or battery core edge.In previous embodiment, grooving is positioned at the edge of pole piece, when grooving is not located at pole piece edge,
And be in other positions, such as when being positioned in the middle of pole piece, after winding, also can form the core that side is concave.
Described above to the disclosed embodiments, makes professional and technical personnel in the field be capable of or uses this practicality new
Type.Multiple amendment to these embodiments will be apparent from for those skilled in the art, is determined herein
The General Principle of justice can realize in the case of without departing from spirit or scope of the present utility model in other embodiments.Cause
This, this utility model is not intended to be limited to embodiment illustrated herein, and is to fit to and principles disclosed herein and new
The widest range that grain husk feature is consistent.
