Abstract
The utility model relates to a negative electrode of a nickel-hydrogen battery, which belongs to the field of a battery. The utility model is composed of a metallic connecting plate and a negative plate of hydrogen-storing alloy. Two sides of the metallic connecting plate are respectively connected with the negative plate of hydrogen-storing alloy, and the metallic connecting plate is clamped in the middle by the negative plate of hydrogen-storing alloy; the metallic connecting plate and the negative plate of hydrogen-storing alloy are connected into a whole by the method of spot welding. The negative electrode of a nickel-hydrogen battery of the utility model has the advantages of high capacity, good electrical conductivity, low cost, convenient production, and rapid production, and is a negative electrode suitable for producing in mass button nickel-hydrogen batteries.
Description
The negative pole of the utility model Ni-MH battery belongs to field of batteries, particularly a kind of ni-mh button cell that relates to.
The negative pole of present many Ni-MH batteries be adopt perforated steel ribbon or copper mesh or nickel foam etc. as the hydrogen storage alloy negative sheet substrate, then hydrogen bearing alloy, binding agent, water etc. are modulated to cathode size by a certain percentage, through slurry with cathode size be coated on the substrate, again drying, be rolled into certain thickness pole plate, this is a common method of making the negative plates of Ni-MH battery.For the pillar Ni-MH battery, the negative plates of said method production is cut into certain size, positive plate and membrane coil coiled one with certain size become pole piece.For the button Ni-MH battery, the general method that adopts folding pole piece, be about to be cut into negative plate, positive plate and the barrier film of certain size folding after, put into battery case.
The purpose of this utility model is to provide a kind of high power capacity, the nickel-hydrogen battery negative pole that conducts electricity very well, make easy, produce fast, the negative pole that is suitable for button cell is produced in a large number.
The purpose of this utility model reaches by following measure, it is by metal connecting sheet, the hydrogen storage alloy negative sheet is formed, two at metal connecting sheet connect the hydrogen storage alloy negative sheet respectively, the hydrogen storage alloy negative sheet is clipped in the middle metal connecting sheet, adopt the method for spot welding to connect as a whole, the main effect of metal connecting sheet is the conductor that plays between the negative electrode active material, metal connecting sheet adopts metal material, as nickel plated steel strip, nickel plating punching steel band, copper strips, copper mesh, nickel strap, nickel screen etc., thickness for metal connecting sheet does not have special requirement, the thickness range of metal connecting sheet is 0.05-0.2mm, with metal material put the people dash touch in, punching becomes different shape and size, and as 2-4 circular linking to each other, perhaps 2-4 is individual square continuous, perhaps 2-4 ellipse links to each other, perhaps 2-4 rhombus metal connector of linking to each other and waiting, hydrogen storage alloy negative sheet THICKNESS CONTROL in the scope of 0.2-0.4mm, with pole plate put the people dash touch in, punching becomes different shape, can be circular, perhaps square, perhaps oval, perhaps rhombus etc., getting a kind of shape metal connector, 2 negative plates are clamped a shape body of brace, is their spot welding one with the method for spot welding, solder joint number do not have special requirement, get final product with 3-5 solder joint.
Nickel-hydrogen battery negative pole high power capacity of the present utility model, conduct electricity very well, production cost is low, producing easyly, quick, is a kind of negative pole that is suitable for producing in a large number the button Ni-MH battery, especially in the production process of pillar Ni-MH battery, can produce the leftover pieces of many hydrogen storage alloy negative sheets, adopt this method just these leftover pieces punchings can be become the needed shape of button cell cathode, with metal connecting sheet point postwelding, as the negative pole of button cell.
Accompanying drawing 1 is a metal connecting sheet structural representation of the present utility model.
Accompanying drawing 3 is structural representations of the present utility model.
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1, the main effect of metal connecting sheet 1 of the present utility model is the conductor that plays between the negative electrode active material, metal connecting sheet adopts metal material, as nickel plated steel strip, nickel plating punching steel band, copper strips, copper mesh, nickel strap, nickel screens etc. do not have special requirement for the thickness of metal connecting sheet, the thickness range of metal connecting sheet is 0.05-0.2mm, with metal material put the people dash touch in, punching becomes different shape and size, and is circular in this way, perhaps square, perhaps oval, perhaps rhombus etc. also can be circular continuous as 2-4.
As shown in Figure 2, hydrogen storage alloy negative sheet 2 of the present utility model is that hydrogen bearing alloy, binding agent, water etc. are modulated to cathode size by a certain percentage, through slurry with cathode size be coated on the substrate, again drying, be rolled into certain thickness pole plate, THICKNESS CONTROL in the scope of 0.2-0.4mm, with pole plate put the people dash touch in, punching becomes different shape, negative plate is circular, perhaps square, and is perhaps oval, perhaps rhombus etc. is selected circular.
As shown in Figure 3, the present invention is by metal connecting sheet 1, hydrogen storage alloy negative sheet 2 is formed, two at metal connecting sheet 1 connect hydrogen storage alloy negative sheet 2 respectively, the hydrogen storage alloy negative sheet is clipped in the middle metal connecting sheet, adopt the method for spot welding to connect as a whole, the main effect of metal connecting sheet is the conductor that plays between the negative electrode active material, and metal connecting sheet adopts metal material, and punching becomes different shape and size, can be circular, perhaps square, perhaps oval, perhaps rhombus etc., also can be as 2-4 circular linking to each other, perhaps 2-4 square linking to each other, perhaps 2-4 ellipse links to each other, perhaps 2-4 the metal connector that rhombus links to each other and waits, the hydrogen storage alloy negative sheet is that the pole plate punching is become different shape, can be circular, perhaps square, perhaps oval, perhaps rhombus etc., getting a kind of shape metal connector, 2 negative plates are clamped a shape body of brace, is their spot welding one with the method for spot welding.
