Abstract
This invention relates to a soft package liquid Li-ion battery characterizing that the battery case is a soft package made of A1 plastic composite film and a solid fixed frame for fixing the cells inside the wall in which the fixed frame is a porous frame made of metal material or nonmetal, the case is a solid fixed frame and the inner cone is a soft package encapsulating cells.
Description
Technical field
The present invention relates to a kind of flexible package liquid lithium ion accumulator, belong to energy technology field.
Background of invention
General liquid lithium ion accumulator all adopts metal shell, on cover plate or shell, explosion-protection equipment is housed, weak point is shell and cover plate processed complex, cost height, heavier, and battery is made also that processing technology complexity, equipment have high input, the battery rate of finished products is low, sometimes may be because of the explosion-protection equipment shortcoming such as have an accident that lost efficacy.For this reason, present liquid lithium ion accumulator also has and adopts flexible package, promptly replaces metal shell with aluminum-plastic composite membrane.But simply replace metal shell and do not make the effect that other change can not be played other people's satisfaction with flexible packing material, because the intensity of flexible packing material is limited, battery in charge and discharge process because the variation of electrode material lattice, make electrode the breathing phenomenon occur, therefore distance can change between cathode-anode plate, if this variation surpasses certain limit, then battery performance rapid deterioration, even cisco unity malfunction.Therefore, need to guarantee that distance between battery pole plates is in a little and very narrow excursion.And flexible packing material can not play such effect.The flexible package liquid lithium ion technology of Holland Philips company is to add polymeric rivet perpendicular to the pole plate direction between battery lead plate, makes polar plate spacing from remaining on certain limit, the outside batteries flexible package.The position that adds the polymer latex fixed polar plate between the both positive and negative polarity of liquid lithium ion accumulator in flexible package of some companies of Japan.Shortcomings such as there is complex process in the liquid lithium ion accumulator of above-mentioned two kinds of method manufacturings, and rate of finished products is low, and equipment investment is big.
Summary of the invention
The objective of the invention is shortcoming and deficiency, and provide a kind of manufacture method simple flexible package liquid lithium ion accumulator, thereby improved properties of product, also improved rate of finished products, reduced cost in order to overcome above-mentioned prior art.
The objective of the invention is to realize by following technical proposal:
The flexible package liquid lithium ion accumulator, comprise positive pole (1), negative pole (2), barrier film (3), electrolyte and shell (4), the shell that it is characterized in that storage battery is the flexible package body with plastic-aluminum combined film production, adjacent flexible package inwall be the hard fixed mount (5) of self-contained battery utmost point group, hard fixed mount is the porous framework shape that metal material or nonmetallic materials are made.
The shell of storage battery also can be the hard fixed mount of the porous framework shape of metal material or nonmetallic materials making, and internal layer is the flexible package body with the packaged battery utmost point group of plastic-aluminum combined film production; The hole shape of hard fixed mount can be circular hole, rectangular opening, polygonal hole and irregularly shaped; Hard fixed mount can be regular hexahedron, cylinder, arc hexahedron; Described metal material is aluminium, aluminium alloy, stainless steel, nickel or copper; Described nonmetallic materials are polypropylene, polyethylene, the polytetrafluoroethylene of rigid plastics; Described hard fixed mount also can be the atresia frame shape.
Owing to adopt technique scheme, make the technology of the present invention compared with the prior art, advantage and effect such as have that manufacture method is simple, finished product rate height, cost are low, stable performance, fail safe are good.
Description of drawings:
Fig. 1 is a flexible package liquid lithium ion accumulator structural representation of the present invention.
Embodiment
The flexible package liquid lithium ion accumulator, as shown in Figure 1, it comprises positive pole (1), negative pole (2), barrier film (3), electrolyte (not shown) and shell (4), the shell of storage battery is the flexible package body of plastic-aluminum combined film production, it can improve battery weight specific energy and fail safe, and hot pressing is shaped simultaneously, the effect of play sealing, isolating, its technology is simple, and equipment investment is few.The hard fixed mount (5) that adjacent flexible package inwalls are self-contained battery utmost point group, hard fixed mount is a porous framework shape, it promptly plays self-contained battery utmost point group, keep the positive and negative distance between plates of battery from effect, can reduce simultaneously the weight of storage battery again, and hard fixed mount add can adopt existing porous plate folding shape man-hour after welding procedure be shaped, saved laser welding process commonly used, reduce production costs.Hard fixed mount available metal material is aluminium, aluminium alloy, stainless steel, nickel and copper etc., polypropylene, polyethylene, polytetrafluoroethylene that also available nonmetallic materials are rigid plastics.
The hole shape of the hard fixed mount of porous can be circular hole, rectangular opening, polygonal hole and irregular hole.Fixed frame also can be an atresia frame shape (not shown).The space that hard fixed mount surrounds can be regular hexahedron, cylinder, arc hexahedron and other shape that needs, and makes product variation more.
Flexible package liquid lithium ion accumulator of the present invention, the hard fixed mount (not shown) of porous framework shape that its shell is also made of metal material or nonmetallic materials, internal layer can reduce weight equally with plastic-aluminum combined film production flexible package sealed cell utmost point group, process easy, safe and reliable.
In a word, the shell of two kinds of structures, promptly hard fixed mount be at skin, and flexible package is at internal layer, or flexible package is at skin, and flexible package is at internal layer, and not only manufacture method is more flexible, and has increased kind.
Claims (6)
1. flexible package liquid lithium ion accumulator, comprise positive pole (1), negative pole (2), barrier film (3), electrolyte and shell (4), the shell that it is characterized in that storage battery is the flexible package body with plastic-aluminum combined film production, adjacent flexible package inwall be the hard fixed mount (5) of self-contained battery utmost point group, hard fixed mount is the porous framework shape that metal material or nonmetallic materials are made.
