Guidance tape is completed.
Meanwhile earliest anode directly utilizes nickel foam, gas distribution, cathode adds one layer of air flue flase floor silver-colored on the net, utilizes gas
Road gas distribution.Till now, the metal of air flue flase floor and battery support outline border is combined together to form air flue plate, anode gas distribution
It is small in the contact area of contact bubble pond piece as cathode gas distribution.Cathode is the reticular structure of double silver net, gas and cell piece
Contact area it is uncertain, but because the metal profile of silver-colored net foam nickel adds air flue, utilize air flue gas distribution.It meanwhile being battery
The air flue of piece gas distribution uses straight air flue on air flue plate, and on pile supporter, battery electricity-taking is completed by nickel foam.
But this structure has many shortcoming, in this one side of cell piece anode, cell piece and air flue are separated by nickel foam,
Anode gas will not directly contact cell piece, further, since air flue is straight air flue, air flue is small in size, the dislocation in the hole of gas and electricity.
Knowing in double silver net has a large amount of meshes to misplace, and is plugged, so the contact surface of gas and cell piece is equally little.But silver net is originally
Body belongs to harder structure.Also, in order to make silver-colored net be connected with cell piece cathode, and need to apply certain external force.As a result,
Battery gas distribution unevenness problem is resulted in, electrode and cell piece contact firmly.
In view of the above shortcomings, the designer, is actively subject to research and innovation, to found a kind of one with air flue

Ontology disconnects.
Further, above-mentioned a kind of integral electrode with air flue, wherein be distributed copper on the electrode body and apply
Layer or nickel coating or silvering or platinum coating.
Further, above-mentioned a kind of integral electrode with air flue, wherein the air flue plate is L-shaped, is provided with
Circular arc bending.
Further, above-mentioned a kind of integral electrode with air flue, wherein the contact surface is plane, described
Plane is parallel with horizontal plane benchmark.
Further, above-mentioned a kind of integral electrode with air flue, wherein the edge of the electrode body is arranged
There is circular arc chamfering.
Still further, a kind of above-mentioned integral electrode with air flue, wherein the air flue plate is in the consistent side of opening
Formula arrangement；Or in opening relative mode arrangement；Or it is dislocatedly distributed in opening an angle of 90 degrees.
According to the above aspect of the present invention, the present invention has at least the following advantages:
1, air flue plate uses stamping, does not need to reuse etching and processing convenient for batch machining, and manufacturing cost is low, adds
Work is high-efficient.
