It includes casing and a plurality of core, the sunken a plurality of recess that is formed with in casing upper end, in the core counterpoint embedded Groove, the core includes a plurality of positive pole thin slice and negative pole thin slice, a plurality of positive pole thin slice and negative pole thin slice misplace each other, and the annular is laminated and locate the reservation at the center pin has a space, the separator has been placed between positive pole thin slice and the negative pole thin slice, the lower extreme is provided with the loop seal on the core, the separation interlayer has still been laid to the core periphery, the connection piece is installed to loop seal machinery, the connection piece sets up a plurality of electrode foot. The utility model discloses it has a space to locate to reserve at the core center pin, utilizes the space to increase on the one hand and gives expansion space when positive pole thin slice and the tiny inflation of negative pole thin slice emergence are given to positive pole thin slice and negative pole thin slice and external area of contact, on the other hand, when preventing to free tiny inflation, directly leads to holistic damage.

Description

A kind of electric core structure of lithium battery

Technical field

This utility model relates to cell art, especially a kind of electric core structure of lithium battery.

Background technology

It is known that along with science and technology development, lithium battery has become as the conventional device of power supply. At present, existing lithium battery is when discharge and recharge, because of improper use, easily expands or electrolyte leakage, Once occur, user will be caused life threat.

Utility model content

For above-mentioned the deficiencies in the prior art, the purpose of this utility model is to provide a kind of lithium electricity Pond core strueture.

To achieve these goals, this utility model adopts the following technical scheme that

A kind of electric core structure of lithium battery, it includes housing and several core bodys, described housing upper end concave shape Becoming and have several grooves, described core body para-position embeds in groove, and described core body includes several anode thin slices And cathode sheet, several described anode thin slices and cathode sheet mutual dislocation ring attaching are incorporated in central shaft Place is reserved with a space, is placed with separator, on described core body between described anode thin slice and cathode sheet Lower end is provided with loop seal, and described core body periphery is also equipped with separation interlayer, described loop seal machinery Being provided with connection sheet, described connection sheet arranges several electrode foot.

Preferably, it also includes that electrode top plate, described electrode top plate para-position are fastened on housing, described electricity The upper end of pole top board is provided with several terminals, and described terminal sleeve is connected in corresponding electrode foot.

Preferably, described electrode top plate is further opened with the through hole that quantity is equal with number of recesses, described through hole Connect with groove, in described through hole, be also placed with stopper.

Preferably, the height of described separator is less than anode thin slice and the height of cathode sheet.

Preferably, described housing bottom periphery is additionally provided with for the bonding jumper fixed with external structure.

Owing to have employed such scheme, this utility model realizes the discharge and recharge of many power by multiple core bodys；With Time, it is reserved with a space in central axis, utilizes space on the one hand to increase anode thin slice and cathode sheet Give swollen when giving anode thin slice and cathode sheet generation fine expansive with extraneous contact area, another aspect Swollen space, when preventing from freeing fine expansive, directly results in overall damage, its simple in construction, operation Convenient, there is the strongest practicality.

Detailed description of the invention

Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail, but this utility model can Implement with the multitude of different ways being defined by the claims and covering.

As shown in Figure 1 to Figure 3, a kind of electric core structure of lithium battery that the present embodiment provides, it includes housing 1 With several core bodys 2, housing 1 upper end depression is formed with several grooves 3, and core body 2 para-position embeds groove In 3, core body 2 includes several anode thin slices 21 and cathode sheet 22, several anode thin slice 21 Hes Cathode sheet 22 mutual dislocation ring attaching is incorporated in central axis and is reserved with a space 25, anode thin slice 21 And between cathode sheet 22, it being placed with separator 23, core body 2 upper and lower side is provided with loop seal 4, core body 2 peripheries are also equipped with separation interlayer 24, and loop seal 4 mechanical erection has connection sheet 5, connect sheet 5 and arrange Several electrode foot 6.

Further, it also includes that electrode top plate 10, electrode top plate 10 para-position are fastened on housing 1, electrode The upper end of top board 10 is provided with several terminals 7, and terminal 7 is socketed in corresponding electrode foot 6.

Further, electrode top plate 10 is further opened with the through hole 9 that quantity is equal with groove 3 quantity, through hole 9 Connect with groove 3, in through hole 9, be also placed with stopper 8.

Further, the height of separator 23 is less than anode thin slice 21 and the height of cathode sheet 22.

Further, housing 1 bottom periphery is additionally provided with for the bonding jumper 11 fixed with external structure.

When the present embodiment uses, only stopper 8 need to be taken out, in groove 3, pour electrolyte into, then will Stopper 8 clogs through hole.

The present embodiment uses multiple core bodys 2 to connect, and to promote charge-discharge electric power, strengthens using effect, with Time, Mei Gexin, 2 are reserved with a space 25 in central axis, utilize this space 25 1 aspect to increase sun Wafer thin 21 and cathode sheet 22 and the contact area of electrolyte, another aspect give anode thin slice 21 and the moon Wafer thin 22 occurs to give expansion space during fine expansive, and when preventing from freeing fine expansive, it is right to directly result in Overall damage.For improving the contact area of anode thin slice 21 and cathode sheet 22 and electrolyte further, The height of its separator 23 is less than anode thin slice 21 and the height of cathode sheet 22.

The present embodiment for convenience of arranging in pairs or groups installation the most in use, then housing 1 bottom periphery be additionally provided with for The bonding jumper 11 fixed with external structure.

These are only preferred embodiment of the present utility model, not thereby limit patent model of the present utility model Enclose, every equivalent structure utilizing this utility model description and accompanying drawing content to be made or equivalence flow process conversion, Or directly or indirectly it is used in other relevant technical fields, the most in like manner it is included in patent of the present utility model In protection domain.
