Description
Technical field
The present invention relates to the Ni-MH secondary battery technical field.
Background technology
Along with the direction of various electrical equipments towards miniaturization, portability develops, battery has obtained application more and more widely.Battery can be divided into primary cell and secondary cell, and primary cell can't recharge after having put electricity, can only discard.Secondary cell is called rechargeable battery again, after having put electricity, can charge again, recycles.So, in electric tool, electronic toy, generally adopt secondary cell.
Nickel-cadmium cell is a kind of secondary cell that uses morely traditionally, but nickel-cadmium cell has had more and more countries that the use of nickel-cadmium cell is limited because used the noxious substance cadmium in the negative pole.Solution is exactly to seek the substitute of nickel-cadmium cell.Ni-MH battery is wherein a kind of, but the cost of Ni-MH battery is higher.In addition, nickel-zinc cell enters people's the visual field gradually, and the negative pole in the nickel-zinc cell uses zinc, has replaced the cadmium that in the past used, and zinc is nontoxic, and is environmentally friendly.And, produce the production equipment that nickel-zinc cell can use nickel-cadmium cell to a great extent, reduce and produce input cost.
The electric core of nickel-zinc cell is made up of anodal, negative pole and the insulation diaphragm that is between the both positive and negative polarity.Positive pole is to be coated with coated positive pole material to make on carrying object.The effect of carrying object mainly is two aspects, and an aspect has provided the carrier that positive electrode depends on, and another aspect is the electric current that produces when collecting positive electrode generation electrochemical reaction, plays the effect of conduction.In traditional production technology, anodal carrying object is selected foaming nickel for use.Foaming nickel is made having on the plastic foam of a large amount of holes plating nickel, has good porosity and conductivity, but along with the rise of nickel valency, the price of foaming nickel also rises thereupon, causes battery cost constantly to increase.In addition, nickel belongs to heavy metal, be diffused in the environment after, also can produce harmful effect to environment.In addition, in traditional manufacturing process, the binding agent that uses in the cell positive material adopts polytetrafluoroethylene to be main sodium carboxymethylcellulose, polyvinyl alcohol or the Sodium Polyacrylate of being equipped with mostly, the shortcoming of using this binding agent to exist is: it is higher that the consumption of binding agent accounts for the ratio of positive electrode, stronger chemical inertness influences the useful life of battery, and also not ideal enough with the bond effect of carrying object.In the process of electric core winding, the phenomenon that the powder of positive electrode comes off easily.
Summary of the invention
Technology of the present invention is dealt with problems and is: overcome and use the weak point of foaming nickel as anode carrying object and employed binding agent in the prior art, a kind of positive pole of novel nickel zincium battery is provided.
Technical solution of the present invention is: nickle zinc secondary battery anode, constitute by carrying object and the positive electrode that is coated on the carrying object, carrying object is a sheet metal with holes, positive electrode is made up of active material, electric conducting material, additive, binding agent, the composition of binding agent and weight percentage are: acrylic acid 1%～5%, acrylate 80%～90%, self-cross linking monomer 5%～15%, divinylbenzene 1%～10%.
The perforated metal sheet is made by steel or by nickel-plated steel, and thickness is 0.1mm～0.5mm, and the hole is a circular port or for square opening or for diamond hole or for non-regular shape hole.
The perforated metal sheet can also draw wire netting for folded-edge cutting.
Positive electrode comprises active material 60%～80% by weight percentage, electric conducting material 15%～25%, additive 3%～10%, binding agent 1%～5%.Wherein, active material is a nickel hydroxide, and electric conducting material is one or more compositions in graphite, carbon black, carbon dust, carbon fiber, nickel powder, metal dust or the metallic fiber.Additive is one or more combinations of following several raw materials: the oxide of the compound of cobalt or cobalt, zinc or zinc, rare earth element and compound thereof.
Described acrylate is a methyl acrylate or for ethyl acrylate or for butyl acrylate or for Isooctyl acrylate monomer.
Described self-cross linking monomer is a kind of in n-methylolacrylamide, hydroxy-ethyl acrylate, hydroxypropyl acrylate, phthalic acid divinyl ester, the diallyl phthalate or is the mixture of more than one materials.
The present invention's beneficial effect compared with prior art is: use the perforated metal sheet of being made by steel or nickel-plated steel or cut and draw the carrying object of wire netting as anode, and use contains the binding agent of the binding agent of self-cross linking monomer as positive electrode, the cross-linking reaction of self-cross linking monomer takes place in the process of oven dry, make the binding agent molecule form the network of an integral body, bond positive electrode and anodal carrying object tightr.The present invention has overcome the weak point of the nickel of use foaming in the past as anode carrying object traditional method, can reduce the use amount of foaming nickel greatly, thereby reduce cost greatly, and can improve the charge and discharge circulation life of battery.
