Pond then cannot be fitted in irregular product, such as when bluetooth earphone is made, it is desirable to battery is loaded into bluetooth ear
In machine, but because bluetooth earphone has certain radian and shape, therefore, the lithium ion battery of rule cannot load irregular
In bluetooth earphone, or allow to lithium ion battery be filled in bluetooth earphone, the volume of lithium ion battery is also restricted,
Its capacity is very little, is the bottleneck of the batch production of this product.
Utility model content
The purpose of this utility model is to provide a kind of crescent soft bag lithium ionic cell, can load irregular bluetooth ear
Inside machine, solve the problems, such as that irregular product cannot install battery or the battery capacity of installation is too small.
To realize above-mentioned technical proposal, the utility model provides a kind of crescent soft bag lithium ionic cell, including battery
Body, the battery body includes aluminum plastic film and battery core bodies, and the aluminum plastic film has a first quarter moon shape, and battery core bodies are arranged on plastic-aluminum
Film inner side, the battery core bodies include multi-disc positive plate and multi-disc negative plate, and every positive plate side is provided with anode ear, per piece
Negative plate side is provided with negative electrode lug, and positive plate and negative plate are alternately arranged, be provided between positive plate and negative plate every
Film.
In above-mentioned technical proposal, by Bag Making Machine hot melting way by two-layer barrier film positive plate bag in centre, then will just
Pole piece and negative plate are successively superimposed, and through hot pressing mode battery core bodies are formed, then weld anode ear and negative electrode lug, form half
Finished product, then semi-finished product are arranged in aluminum plastic film form battery body, then toward the electrolysis that adding ingredient in aluminum plastic film is LiPF6
Liquid, forms battery.Aluminum plastic film is molded when being molded in special-shaped mode, therefore the battery with crescent shape can preferably load tool
In having the bluetooth earphone of certain radian shape, increase the volume of battery, improve battery capacity.
Preferably, the negative plate is wider than positive plate, and barrier film is wider than negative plate, facilitates and is welded after both positive and negative polarity superposition.
Preferably, the anode ear be aluminium-to-nickel band, negative electrode lug is nickel strap, and anode ear is connected with positive plate, negative electrode lug and
Negative plate connects, and anode ear stretches out aluminum plastic film with negative electrode lug, facilitates lug alignment and welding.
Preferably, the barrier film is polystyrene, and thickness is 0.01mm-0.02mm, can be effectively spaced apart positive plate and bear
Pole piece, prevents battery short circuit.
Preferably, the outer arc radius of the battery body are 13.4mm, and the battery with the radian convenient can be filled
In entering irregular bluetooth earphone.
The beneficial effect of a kind of crescent soft bag lithium ionic cell that the utility model is provided is：Its battery body passes through
Positive and negative special-shaped pole piece and abnormity rush shell membrane and form special-shaped crescent shape, can be good at being fitted in irregular bluetooth earphone, and
And due to can be good at being combined into one with irregular bluetooth earphone, do not limited by lithium ion battery volume, therefore relatively
In common battery, its capacity is also bigger, and compared with existing rhombus and column lithium ion battery, the utility model is solved
Irregular product cannot install the too small problem of battery capacity of battery or installation.

Specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clear, complete description, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole
Embodiment.The every other embodiment that this area ordinary person is obtained under the premise of creative work is not made, belongs to
Protection domain of the present utility model.
Embodiment：A kind of crescent soft bag lithium ionic cell.
Referring to figs. 1 to shown in Fig. 3, a kind of crescent soft bag lithium ionic cell, including battery body 8, the battery body 8
