Description
Technical field
This utility model is related to lithium ion battery, especially a kind of ultra-thin Soft Roll parallel connection Li-ion batteries piles.
Background technology
With the improvement of people's living standards and the emergence of post-PC era, smart mobile phone, panel computer, super basis are accelerated
Etc. the market demand of hand-held portable devices；Particularly smart mobile phone, updates very fast, frivolous to become that the market competition is important to sell
Point, is increasingly becoming the market mainstream.As smart machine does thinner and thinner, must require that its component is also more and more frivolous.Battery is
The requisite significant components of smart machine, smart machine more and more thinner mean also less and less to the space of battery assembling,
This requires that cell stack designs need space-efficient as far as possible, and then lifts battery capacity, increases equipment cruising time, and this is right
The design requirement of set of cells also more and more higher.
The content of the invention
Technical problem to be solved in the utility model is to provide a kind of ultra-thin Soft Roll parallel connection Li-ion batteries piles, lifts electricity
Pond group integral space utilization ratio, and then lift set of cells whole volume.
To solve above-mentioned technical problem, the technical solution of the utility model is：A kind of ultra-thin Soft Roll parallel connection lithium ion battery
Group, including the plural battery core being arranged side by side, are connected by insulating tape between adjacent battery core；The head of the battery core
Portion is provided with edge sealing, and edge sealing is arranged on one side position of head of battery core, forms enclosed slot in the opposite side of battery core head；The battery core
The head of group is provided with protection board in enclosed slot, and on protection board, the battery core passes through protection board simultaneously to the tab welding of battery
Connection；One end of the protection board is provided with connection sheet.In this utility model, set of cells has battery core Side by side groupings to form, solid without housing
Fixed, directly by insulating tape adhesion, save space effectively reduces the thickness of set of cells to two battery cores；Ingenious utilization battery core edge sealing
The enclosed slot that structure is formed, protection circuit plate is folded in battery core enclosed slot, and THICKNESS CONTROL gives each battery core within 2.5mm
Save length dimension at least 8mm.
Used as improvement, the connection sheet includes fixed part, connecting portion and contact site, and the fixed part is vertical with connecting portion,
Connecting portion is vertical with contact site, and contact site is connected with fixed part by connecting portion；The fixed part is welded on the welding of protection board
At region.Connection sheet is welded to connect by the fixed part with certain area and protection board, and bonding area is big, the reliability of welding
It is higher.
As improvement, insulating tape is provided with by protection board together with the edge sealing colligation of battery core.Protection board circuit board is first rolled over
Entering the interior bag exterior insulation adhesive tape again of battery core enclosed slot can prevent protection circuit plate from tilting impact set of cells thickness.
The beneficial effect brought compared with prior art by this utility model is：
Set of cells has battery core Side by side groupings to form, and fixes without housing, and two battery cores save empty directly by insulating tape adhesion
Between, effectively reduce the thickness of set of cells；Protection circuit plate is folded into battery core by the enclosed slot that ingenious utilization battery core edge sealing structure is formed
In enclosed slot, the width and length of set of cells are controlled；Protection board circuit board first folds into the interior bag exterior insulation glue again of battery core enclosed slot
Band can prevent protection circuit plate from tilting affects set of cells thickness.
Description of the drawings
Fig. 1 is this utility model lateral plan.
Fig. 2 is this utility model front view.
Specific embodiment
With reference to Figure of description, the utility model is described in further detail.
As shown in Figure 1, 2, a kind of ultra-thin Soft Roll parallel connection Li-ion batteries piles 1, including the plural electricity being arranged side by side
Core 11, is connected by insulating tape 7 between adjacent battery core 11, and set of cells has 11 Side by side groupings of battery core to form, solid without housing
Fixed, directly by insulating tape adhesion, save space effectively reduces the thickness of set of cells, set of cells maximum gauge to two battery cores 11
2.5mm.The present embodiment is provided with two thickness 2.4mm altogether, and the battery core 11 of wide 97mm, long 94mm is spliced side by side.The battery core 11
Head is provided with edge sealing 2 and lug 5, and edge sealing 2 is arranged on one side position of head of battery core 11, is formed in the opposite side of 11 head of battery core
Enclosed slot 3.The head that 11 groups of the battery core is provided with protection board 4 in enclosed slot 3, and the size of protection board 4 is thickness 1.6mm, wide
Protection circuit plate invagination battery core 11 is sealed by 3.8mm, long 186mm, the enclosed slot 3 that ingenious 11 edge sealing of utilization battery core, 2 structure is formed
In groove 3, THICKNESS CONTROL saves length dimension at least 8mm to each battery core 11 within 2.5mm.Protection board 4 first passes through insulating cement
Band is connected with edge sealing 2, is then folded in 11 enclosed slot 3 of battery core of two, makes 1 THICKNESS CONTROL of set of cells within 2.5mm.Protect
