Description
Technical field
The low-pressure injection molding polymer battery that the present invention relates to a kind of polymer battery low-pressure injection molding method for packing and produce with this method.
Background technology
Development along with the lithium-ion electric pool technology, and lithium ion battery is extensively universal, feasible security performance to lithium ion battery more and more comes into one's own, yet the electric core of normal lithium ion aluminum hull still has the explosion potential of minimum probability, because of the shortcoming of itself structure can not be solved, make the higher lighium polymer electricity core of security performance more and more receive publicity.But the encapsulation of lighium polymer electricity core will accomplish that the effective energy volume is big and encapsulate and low price is the difficult problem of each producer's tackling key problem always.
It is six faces with the softer electrostrictive polymer core of six (upper bottom surface, bottom surface, forward and backward a, left side and right flanks) all will will be lived with the encapsulated by structures of plastic cement or similar plastic rubber surface intensity that existing lithium polymer battery packaging technology requires, to strengthen the intensity of electrostrictive polymer core, reach practical requirement.Present a kind of mode is to adopt to go up to carry out ultrasonic technology after lower casing wraps up electric core.Usually upper bottom surface and bottom surface are common plastic rubber surfaces, though it is simple, its thickness is between 0.4 to 0.6mm.The thickness of two-layer sum is just 0.8 to 1.2mm.It is just very difficult that the thickness of plastic rubber surface drops to its injection moulding of 0.4mm from 0.6mm, and in the case, the cell thickness of making battery upper bottom surface and bottom surface with plastic rubber surface will increase 0.8mm at least.Adopt thickness 0.1 to arrive the steel disc of 0.2mm so the technology of upgrading is upper bottom surface and bottom surface, two-layer thickness sum is just between 0.2 to 0.4mm, relatively rationally.But its shortcoming is to have increased baroque two steel discs.And in the time of upper casing and lower casing injection mo(u)lding, before each moulding, in mould, add steel disc.It has not only increased material cost greatly, and has increased the moulding process cost.
Existing a kind of special battery, as Chinese patent application number 200810198733.5 disclosed battery components, its electric core encapsulation is by the electric core guard assembly of reeling at electric core outer surface, battery head assembly, rail unit and battery protective unit are formed the battery profile, fix to the method for inside battery encapsulating again.This battery is because electric core guard assembly wants precision to be fitted on the electric core, and in the process of fitting, be not subjected to the assembling that movable battery head assembly that limits and battery rail unit are also wanted simultaneously and electric core protective unit definitely fits tightly just can reach the conventional tolerance+0.1mm of battery, first: this battery requires also that every single product dimensional accuracy is very high to remedy the preceding rigging error of injection moulding, second: guarantee that battery is controlled in the minimum rigging error.The 3rd: the electric core protective unit winding process of band glue will guarantee that its moulding profile and size also are difficult for.The material cost of battery and processing cost can increase like this.
No matter be that lower casing wraps up and carries out ultrasonic technology behind the electric core and by the electric core guard assembly method of reeling at electric core outer surface in the above-mentioned employing, can not be further reduced at the height that is exactly battery, the profile that is exactly the lithium polymer battery that comes out of made is all unstable, also nonstandard.And all there is the high problem of complex process cost in two kinds of packaging technologies.
