Abstract
The utility model relates to an electrode which provides a new bipolar-plate electrode structure. The utility model is formed by the method that a positive plate and a negative plate are integrated into a whole, and has the advantage of convenient operation. The utility model is used as a battery, for a nickel-hydrogen battery and a nickel-cadmium battery, the discharge platform voltage of the single-body battery is the integer multiple of 1.2 volt, and for a lithium ion battery, the discharge platform voltage of the single-body battery is the integer multiple of 3.6V. The utility model is a bipolar-plate electrode composed of positive materials, negative materials and an afflux plate; the bipolar-plate electrode has three layers, wherein one layer is provided with the positive materials, one layer is provided with the negative materials, and an interlayer is provided with the afflux plate. The afflux plate is a plate-shaped object, wherein both the upper and the lower edges of the plate-shaped object are provided with a circle of lug boss, and the section face of the plate-shaped object is a plate-shaped object in an H shape; furthermore, the edge of the circumference of the afflux plate is molded into a sealing ring by insulating polymer materials, and the lug boss is sealed and insulated; the positive materials and the negative materials are respectively coated in sealing rings at both sides of the afflux plate.
Description
Technical field
The utility model belongs to a kind of electrode, particularly a kind of bipolar sheets electrode.
Background technology
Present battery all is to adopt the one pole sheet, and both positive plate and negative plate were made separately and be used in combination.As: the basic manufacturing process of the positive pole of battery is that nickel foam etc. is as collector, then nickel hydroxide, binding agent, water etc. are modulated to anode sizing agent by a certain percentage, through slurry or coating with anode sizing agent embed in the collector, again drying, be rolled into certain thickness pole plate, this is a common method of making the anode plate of Ni-MH battery.
The basic manufacturing process of negative pole be with perforated steel ribbon or copper mesh or the collector as the hydrogen storage alloy negative sheet such as nickel foam, then hydrogen bearing alloy, binding agent, water etc. are modulated to cathode size by a certain percentage, through slurry or coating with cathode size be coated on the collector, 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 and put into battery case, manufacture pillar ni-mh cell.For the button Ni-MH battery, the general method that adopts folding pole piece is about to be cut into negative plate, positive plate and the barrier film of certain size and puts into battery case after folding, manufactures button ni-mh cell.For the square Ni-MH battery, the general method that adopts is put into battery case after negative plate, positive plate and the barrier film that is about to be cut into certain size stacks, and manufactures the square cell.
Summary of the invention
The utility model provides a kind of structure of brand-new bipolar sheets electrode.
Structure of the present utility model is as follows:
A kind of electrode, he is by positive electrode, the bipolar sheets electrode that negative material and flow collection sheet are formed; The bipolar sheets electrode is three layers, one deck is a positive electrode, one deck is a negative material, the intermediate layer is a flow collection sheet, flow collection sheet be last lower limb one circle boss, section all arranged is I-shaped tablet, in the edge of flow collection sheet, be injection molded into a sealing ring with the macromolecular material that insulate again, with the boss insulated enclosure, positive electrode and negative material are coated in respectively in the sealing ring of both sides of flow collection sheet.
The shape of flow collection sheet can be designed to circle, square, oval, rhombus etc. as required, and the height of the sealing ring of formation is the bipolar sheets height, the preferred 0.05-1mm of flow collection sheet thickness range.
In the battery manufacture process, at the positive electrode of the both sides of flow collection sheet and negative material respectively and be lower than the height at sealing ring edge, both reserved the size of putting into barrier film when making battery.
Flow collection sheet of the present utility model can be metal materials such as nickel plated steel strip or nickel strap; Positive electrode and negative material are employed materials in the prior art, and promptly positive electrode can be the positive electrodes that battery adopted such as Ni-MH battery, ickel-cadmium cell, lithium ion battery; The material of negative pole is the negative materials that battery adopted such as Ni-MH battery, ickel-cadmium cell, lithium ion battery; Encapsulant is that battery generally uses encapsulant as the insulation macromolecular material in the prior art.
The utility model collection positive plate and negative plate are one, easy to use, when using as battery, for Ni-MH battery, ickel-cadmium cell, the discharge platform voltage of monomer whose battery all is 1.2 volts integral multiple, for lithium ion battery, the discharge platform voltage of monomer whose battery all is 3.6 volts integral multiple.
