The zinc-silver cell has simple structure, is easy to be processed and manufactured, has low cost and is a thin zinc-silver cell sealed by a metal-plastic compound packaging membrane and suitable for the power source of a portable electronic product.
Description
Technical field
The present invention relates to a kind of chemical power source.
Background technology
At present, common zinc-silver oxide cell all is to be encapsulated in can or the plastic casing on the market, draws the positive and negative electrode binding post above lid, and vent plug is installed, and structure is comparatively complicated.Produce such zinc-silver oxide cell, required investment of production equipment is bigger, and technology is loaded down with trivial details, the cost height.And, adopt metal or plastic casing can not satisfy requirement on the electronic product size along with the increase of portable type electronic product miniaturization and lightness demand.Therefore, the shell mechanism and the technology of zinc-silver oxide cell are developed and improved, adopt a kind of novel plastic and metal aluminum foil composite material shell, make battery can satisfy the requirement of slimming as zinc-silver oxide cell.Up to the present, on market, do not see the zinc-silver oxide cell of slim, plastics and metal aluminum foil composite material encapsulation as yet.
Summary of the invention
The purpose of this invention is to provide a kind of new type superthin pocket type zinc-silver oxide cell, this battery structure is simple, be easy to processing and manufacturing, slim, to overcome the deficiency that prior art exists.
Zinc-silver oxide cell of the present invention is the zinc-silver oxide cell of metallo-plastic composite package film encapsulation, it comprises insulating tape, barrier film, negative electrode, positive electrode, constitute electric core by positive electrode, barrier film, negative electrode, electricity core and electrolyte are encapsulated in the encapsulation bag, negative electrode, positive electrode are connected with negative collector bar, positive collector bar respectively, on negative collector bar, positive collector bar insulating tape are arranged.
Positive electrode, negative electrode adopt the method that is coated with on metal forming to make, or make at wire netting by roll-in system mould.
Barrier film adopts laminar or coiling form to constitute electric core between negative electrode and positive electrode.
The material of described encapsulation bag is the metallo-plastic composite package film that plastics and metallic aluminium are composited.
Described metallo-plastic composite package film is through compression molding.
Described metallo-plastic composite package film forms the battery case that has the outside with heat sealing machine heat seal edge sealing.
In the direction of positive collector bar of encapsulation and negative collector bar, the edge sealing place and the insulating tape of metallo-plastic composite package film are overlapping.
Described barrier film is a regenerated cellulose film, or non-braiding synthetic fibers nylon, or one or more combinations of polypropylene and non-braiding staple fibre felt.
The invention has the beneficial effects as follows: (1) is simple in structure, processing technology is easy, be easy to manufacturing, during only the electric core that need will prepare is packed the encapsulation bag into, seals behind the filling electrolyte again, promptly can be made into; (2) can realize that battery slimming, shape change arbitrarily; (3) cost is lower; (4) equipment investment is few.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Embodiment
The invention will be further described below in conjunction with accompanying drawing.
In the drawings, zinc-silver oxide cell mainly is made of negative collector bar 1, positive collector bar 2, insulating tape 3, barrier film 4, negative electrode 5, electrolyte 6, positive electrode 7, encapsulation bag 8 etc.
The active material of described positive electrode 7 is a silver oxide, and the active material of negative electrode 5 is a metallic zinc.Positive electrode 7, negative electrode 5 can adopt the method that is coated with or be pressed in wire netting then by roll-in system film and make on metal forming.Positive electrode 7 can not directly contact with negative electrode 5, separate with barrier film 4, and adopt laminar or coiling form to constitute electric core.The positive terminal of electricity core is drawn by positive collector bar 2, and negative pole end is drawn by negative collector bar 1, can pass through melt process fixed insulation adhesive tape 3 on positive collector bar 2, negative collector bar 1.
Described barrier film 4 can be one or more combinations of regenerated cellulose film or non-braiding synthetic fibers nylon or polypropylene and non-braiding staple fibre felt.The height of barrier film 4 will exceed positive electrode 7 and negative electrode 5.
Described electrolyte 6 is potassium hydroxide aqueous solution, and the filling of electrolyte 6 will be carried out after electric core is packed encapsulation bag 8 into.
The material of described encapsulation bag 8 is the metallo-plastic composite package film that plastics and metallic aluminium are composited, and this film needs through compression molding, and compact dimensions is decided according to electric core size.Zinc-silver oxide cell electricity core is placed between two measure-alike formed package films, with heat sealing machine heat seal edge sealing, forms the battery case that has the outside, promptly the encapsulation bag 8, and is overlapping with insulating tape 3 at the edge sealing place of positive collector bar 2 and negative collector bar 1.
