Abstract
The utility model discloses a lithium ion battery belongs to lithium ion battery technical field. The utility model discloses a following technical scheme realizes: in lithium ion battery, electric core arrange the aluminum hull of indent in, aluminum hull a week protrusion a week and the heat -seal of plastic -aluminum membrane, the hot -blast edge of aluminum hull and plastic -aluminum membrane covers and has PP to glue, and the two poles of the earth ear of electric core stretches out the seal that aluminum hull and plastic -aluminum membrane are constituteed. This novel rectangular cell simple structure prepares with low costsly, and the plastic -aluminum membrane does not receive mechanical drawing, and the battery extranal packing is fast reliable, and this novel square lithium ion battery is fit for the large -scale production.
Description
Technical field
The utility model discloses a kind of lithium ion battery, belong to technical field of lithium ion.
Background technology
Lithium ion battery energy density is large, and good rate capability and safety, environmental protection, become current mankind's main energy sources product.Soft bag lithium ionic cell security performance is relatively better, but housing material requires that housing processing is harsh, the inner aluminium lamination of aluminum plastic film stretches can not be too large, thickness of shell is restricted, this also constrains the development of soft-package battery, and soft-package battery to rush the required precision of shell Mould Machining high, die cost is higher, and soft bag lithium ionic cell is remodeled costly.
Summary of the invention
For the problems referred to above, the utility model provides a kind of lithium ion battery, and this square lithium ion battery structure is simple, and preparation cost is low, lithium ion battery long service life, is applicable to scale application.
To achieve these goals, the utility model adopts following technical scheme to realize:
Lithium ion battery, battery core is placed in the aluminum hull of indent, and aluminum hull one week protrudes one week and aluminum plastic film seals, and the hot blast edge of aluminum hull and aluminum plastic film is covered with PP glue, and two lugs of battery core stretch out the seal that aluminum hull and aluminum plastic film form.
As preferably, described anode ear and negative electrode lug stretch out seal in the same side of battery core.
As preferably, described anode ear and negative electrode lug stretch out seal at the opposite side of battery core.
As preferably, described aluminum hull is square.
This Novel square battery structure is simple, and preparation cost is low, and aluminum plastic film is not by mechanical stretching, and battery external packing is reliably solid, and this Novel lithium ion cell in square is applicable to large-scale production.
Accompanying drawing explanation
Fig. 1 is the utility model plan structure schematic diagram;
Fig. 2 is the left TV structure schematic diagram of the utility model;
Fig. 3 is slicing structural representation in the middle part of the utility model;
Reference numeral: 1, battery core, 2, aluminum hull, 3, aluminum plastic film, 101, lug, 201, pp glue.
specific implementation method
Also by reference to the accompanying drawings the technical solution of the utility model is further described below by embodiment.
As depicted in figs. 1 and 2, lithium ion battery, this rectangular lithium ion battery is by inner battery core 1, and aluminum hull 2 and aluminum plastic film 3 form.Aluminum hull is square, and the inside of aluminum hull forms depression and puts into described battery core 1, and battery core shape is also square.
Battery core adopts one to bring out lug 101 form or lug is stretched out in two pairs of sides, and surrounding seal district, aluminum hull edge is stained with one deck PP glue 201, and battery core 1 is positioned in the middle of aluminum hull 2 and aluminum plastic film 3, aluminum hull 2 and the heat-sealing of aluminum plastic film 3 surrounding.
This Novel square battery structure is simple, and preparation cost is low, and aluminum plastic film is not by mechanical stretching, and battery external packing is reliably solid, and this Novel lithium ion cell in square is applicable to large-scale production.
