Abstract
The invention discloses an inline collector of a power battery module, comprising sealed plastic (1) and an inline collecting metalwork (2). The inline collecting metalwork (2) is composed of two metal plates and an electrical conductor connecting the two metal plates, wherein the inline collecting metalwork (2) is wholly sealed and included in the sealed plastic (1) except the metal plate surfaces at both sides. The invention not only can avoid the direct welding of adjacent battery units of the power battery module to realize fine collection of positive and negative electrode plates of a monomer battery but also can realize the interior bonding of adjacent monomer batteries and separated inline collector.
Description
Technical field
The invention belongs to field of batteries, be specifically related to a kind of inner-union current collector of power battery module.
Background technology
In recent years, propose " pole type afflux structure " (seeing accompanying drawing 1 for details), " end face weldering collector " multiple afflux structures such as (seeing accompanying drawing 2 for details), improved the power-performance of battery, had bigger development and breakthrough.
In some such battery, in order to realize the modularization of battery, often linking to each other by connection sheet outer type or binding post inner Join between the adjacent monomer forms.Adopt the mode of outer type to carry out modular combination, space availability ratio is lower; Adopt the mode of inner Join to carry out modular combination, structure is more compact, and space availability ratio is higher.Utilize the positive collector plate and the negative collector plate of binding post inner Join adjacent monomer battery, binding post is connected by welding manner with positive and negative collector plate, cause adjacent cells electrolyte string lattice, collector plate stress to concentrate instability problems such as tearing welding position easily easily.
Summary of the invention
The purpose of this invention is to provide a kind of adjacent cell of power battery module of can avoiding and directly weld, can realize the good afflux of cell positive-negative electrode plate, can realize the inner Join of adjacent monomer battery and the inner-union current collector of separation again.
Technical scheme of the present invention is:
A kind of inner-union current collector of power battery module, comprise sealing plastic cement 1 and inline afflux metalwork 2, described inline afflux metalwork 2 is made up of with the electric conductor that is connected two metallic plates two metallic plates, and wherein inline afflux metalwork 2 whole sealed packets except that the metallic plate face of both sides are combined in the sealing plastic cement 1.
Wherein said electric conductor communicates between two parallel metallic plates and with them, it is the structure that two metallic plates and the electric conductor that is connected two metallic plates of inline afflux metalwork 2 constitutes H type structure or similar H type, (concrete as the electric conductor between two metallic plates as a among Fig. 3 greater than having the cavity of various type shapes, electric conductor to be " ten " word shape or " worker " word shape etc. in 1, electric conductor, b, c, d, e, f, structures such as g).The metallic plate face of inline afflux metalwork 2 both sides links to each other with negative pole with the positive pole of electric core respectively.
Sealing plastic cement 1 is ABS, PP (polypropylene), PA (nylon), PPO (polyphenylene oxide) or its modification doped and compounded material, and inline afflux metalwork 2 is nickel, stainless steel, mild steel, copper, aluminium or its two or more composite material.
Sealing plastic cement and inline afflux metalwork can carry out combination by injection moulding, hot melt or machine riveting mode respectively.The left and right sides metal covering of inner-union current collector connects the positive electrode plate and the negative electrode plate of adjacent cells electricity core respectively, and connected mode is laser welding, electron beam welding, plasma welding or resistance welded.Contain some positive electrode plates, barrier film and negative electrode plate in each unit electricity core in the battery module, it stacks order is negative pole, barrier film, positive pole, barrier film, negative pole.Anodal unified being welded on the inner-union current collector, negative pole is then unified to be welded on another inner-union current collector, thereby constitute single electric core, linking to each other before and after the electric core constitutes electric core group (as shown in Figure 5), and welding manner can be respectively laser welding, electron beam welding, plasma welding or resistance welded.Isolation in the battery module between the single electric core realizes by this inner-union current collector, is coated with plastic cement around this inner-union current collector, can realize encapsulation by the mode and the battery module main casing of ultrasonic, heat-sealing, machine riveting or adhesive bond respectively.
The present invention has adopted more reliable afflux structure body, thereby has improved the power-performance and the stable and consistent of battery module.

Embodiment
The present invention is further illustrated below in conjunction with drawings and Examples.
As shown in Figure 4, thereby two metallic plates constitute H type structure with the electric conductor that is connected two metallic plates and form inline afflux metalwork 2 (material can be nickel, stainless steel, mild steel, copper, aluminium or its composite material), with ABS, PP, PA, PPO or the inline afflux metalwork 2 of its modification doped and compounded material seal inclusion, only reserve the outer plate surface of two metallic plates of both sides, constitute inner-union current collector J.
As shown in Figure 5, the positive plate and the negative plate that scribble active material are respectively isolated by barrier film, alternately be superimposed and form the pole plate bundle, the positive pole unification of this pole plate bundle is welded on the inner-union current collector of pole plate Shu Yiduan, thereby negative pole is then unified to be welded on another inner-union current collector of the pole plate bundle other end and to constitute single electric core, and linking to each other before and after a plurality of electric cores constitutes electric core group.A plurality of electric core groups finally constitute battery by series, parallel or connection in series-parallel.The present invention can apply to metal hydride-ickel accumulator, also can be used for the making of other secondary battery module (as: lead-acid battery, lithium-ions battery, nickel-zinc battery, fuel cell etc.).
Two metallic plate faces of inner-union current collector can be realized the good afflux of positive-negative electrode plate, sealing plastic cement all around can be separated adjacent electric core mutually, thereby also can fix electric core group by the mode and the encapsulation of battery module main casing of ultrasonic, heat-sealing, machine riveting or adhesive bond respectively simultaneously.
