Abstract
The utility model relates to an anode board of a square lithium-manganese dioxide battery with the advantages of large capacity, high power and low temperature resistance. The anode board consists of the compound tablets containing an anode active object, a conductive agent and a binding agent as well as a tab. One end of the square or the quadrate netty current collector of the utility model is fixedly provided with the tab; the two sides of the netty current collector are provided with the compound tablets; the compound tablets at the two sides of the netty current collector are closely jointed and cover the surrounding of the netty current collector. The anode board adopts a firmer tinsel hauling net or a punching net as the netty current collector, thus being hard to coil and deform; the adhered compound tablets containing the compound tablets containing the anode active object, the conductive agent and the binding agent are very firm and not chapped or fallen off. The angle of the anode active object can be remarkably increased by the compound tablets and the tablets at the two sides of the netty current collector to pressure jointing. The anode board has the excellent advantages of being convenient for manufacturing the square compound battery cell with high capacity.
Description
Technical field
The utility model belongs to battery structure, particularly relates to a kind of big capacity, high power, low temperature resistant square lithium-manganese dioxide battery positive plate.
Background technology
At present, the navigation mark lamp power generally adopts lead acid accumulator and zinc-air cell both at home and abroad, and China is based on zinc-air cell.Though more than two kinds of batteries can satisfy navigation light substantially to the big capacity of battery supply, high-power requirement, can not be in the particularly normal use under environment ice period of low temperature environment.Its reason is respectively: lead acid accumulator specific energy at low temperatures reduces significantly; Zinc-air cell can not obtain replenish air in ice-bound enclosed cell storehouse.In addition, the large volume of lead acid accumulator, high weight and need the defective of frequent charge also to limit its scope of application.
Lithium-manganese dioxide battery has high voltage, high-energy-density, high-specific-power, low self-discharge rate, storage life is long and the characteristics of serviceability temperature wide ranges (30 ℃-+60 ℃), can be used as the navigation mark lamp power theoretically.
The electric core of existing lithium-manganese dioxide battery generally is a column type, and its positive pole is shaped as bar-shaped, and a kind of formation is that the afflux guipure that will be coated with coated positive pole material is processed into rolled, another kind of constitute be positive electrode is molded into cylindric.Obviously the electric core of the existing lithium-manganese dioxide battery of employing constitutes big capacity, high power navigation light volume of battery specific energy is lower.For the navigation light battery, adopt square electric core can improve its volumetric specific energy greatly, the positive/negative plate of square electric core should have the shape identical with electric core.
Summary of the invention
The utility model is the above-mentioned technical problem that exists for the anodal shape that solves as the lead acid accumulator of navigation light power supply and zinc-air cell and existing lithium-manganese dioxide battery column type core strueture, and big capacity, high power, the low temperature resistant square lithium-manganese dioxide battery positive plate of the square electric core of a kind of suitable manufacturing are provided.
The utility model is to take following technical scheme in order to solve the problems of the technologies described above: this lithium-manganese dioxide battery positive plate is made up of the mixture compressing tablet and the lug that contain positive active material, conductive agent and binder, an end that it is characterized in that square or rectangular reticulated collectors is fixed with lug, the both sides of reticulated collectors are provided with the mixture compressing tablet, and the mixture compressing tablet fluid-tight engagement of reticulated collectors both sides also covers the periphery of reticulated collectors.
The utility model can also be taked following technical measures:
Its thickness range of described positive plate is 2-10mm.
Described square or rectangular reticulated collectors is to be drawn in the net or sheet metal punching net constitutes by metal forming.
Described reticulated collectors and lug welding are fixing.
Described positive plate is fitted with the glass adhesive tape on the compressing tablet surface of corresponding reticulated collectors and lug weld part.
The beneficial effects of the utility model and advantage are: this square positive plate adopt the more strong for example stainless metal forming of metal draw in the net or sheet metal punching net as reticulated collectors, positive plate is difficult for curling and distortion, the mixture compressing tablet that contains positive active material, conductive agent and binding agent that adheres to through evidence is very firm, does not chap, does not come off.The form of employing mixture compressing tablet and reticulated collectors both sides compressing tablet not only help its firm attachment by the fluid-tight engagement of pressure, more importantly be the density that has obviously increased positive active material, thereby the high power capacity of combined electrical core, high power are achieved.The utlity model has the outstanding advantage of being convenient to make high power capacity, high power and the needed square electric core of low temperature resistant lithium-manganese dioxide navigation light battery supply, this square positive plate also can be used for the lithium-manganese dioxide battery with above-mentioned advantage of other purposes.
