Background
The alkaline manganese cell is developed on the basis of alkaline zinc-manganese cell, and is also called as mercury-free alkaline manganese cell because of the application of mercury-free zinc powder and novel additive. The battery has the characteristics that while the discharge characteristic of the primary alkaline battery is not changed, the alkaline manganese battery has the following characteristics: 1. the open circuit voltage is 1.5V;2. the working temperature range is wide between minus 20 ℃ and 60 ℃, and the device is suitable for alpine regions; 3. the capacity of the acid zinc-manganese battery is about 5 times of that of the acid zinc-manganese battery after heavy current continuous discharge; 4. its low-temp discharge performance is also good. The alkaline manganese battery has the advantages of wide application.
The bottom sealing ring of the existing alkaline manganese battery is of a high-molecular structure, is generally nylon or PP, and the material contains certain moisture and has a gap, so that the material is exposed in the air for a long time and is in contact with the air, the moisture can be lost, the anti-explosion pressure of the sealing ring is reduced, the sealing ring is broken to cause battery leakage after a certain degree, even the moisture in the battery can be exchanged with the outside through the gap of the sealing ring, the service life of the battery is shortened, and the use performance is reduced. In addition, the positive electrode and the negative electrode at the bottom of the existing alkaline manganese battery are separated by a certain space gap, and a layer of trademark label is wrapped outside the alkaline manganese battery, so that the trademark label covers the space gap between the positive electrode and the negative electrode to form an isolation protective layer, thereby achieving the effect of insulation protection. However, the label is thin, and the insulation protection effect is not good enough, for example, the hard elastic sheet is easy to scratch the label, so that the anode and the cathode of the alkaline manganese battery are directly connected to form a short circuit, and the phenomena of heating, alkali leakage, liquid leakage and the like can occur.
SUMMERY OF THE UTILITY MODEL
In order to overcome prior art not enough, the utility model aims to provide an alkali-manganese cell with high sealing performance can continue to play the isolation electrolyte effect after the sealing washer became invalid on the one hand, solidification sealing washer resistance to compression explosion-proof performance, on the other hand it can be effectively with the interelectrode clearance packing of alkali-manganese cell positive negative, even the trade mark label still plays good insulation protection when torn by the shell fragment fish tail.
In order to solve the above problem, the utility model discloses the technical scheme who adopts as follows:
an alkaline manganese battery sequentially comprises a negative electrode collector bar, a negative electrode filler cavity, isolation paper, a positive electrode filler cavity, conductive graphite, a steel shell, an outer label and a sealing device positioned at the bottom of the battery from inside to outside, wherein the sealing device comprises a metal spacer positioned at the lower end of the negative electrode filler cavity; a sealing ring is positioned in the steel shell and sleeved on the negative collector bar to seal the negative filler cavity; and a negative electrode bottom cover is arranged below the sealing ring, an annular concave cavity which is sunken towards the inside of the battery is formed in the negative electrode bottom cover, and curing glue is filled in the annular concave cavity.
The negative pole filler cavity be equipped with the negative pole filler.
Anodal packing chamber be equipped with anodal filler.
In the preferred scheme, the sealing washer scribble the negative pole sealing agent with the contact surface of negative pole current collecting rod, scribble the negative pole sealing agent on its and the contact surface of box hat.
In the preferred scheme, the solidification is glued and is glued for ultraviolet curing (UV glues), carries out 360 degrees complete fillings to the annular cavity, can make positive negative pole keep apart completely, the curing time that the UV glued is short moreover, does benefit to the rapid solidification, high temperature resistant accords with the use difference in temperature of alkali-manganese cell, and the positive negative pole insulation protection of utmost point suitable alkali-manganese cell can prevent the alkali-manganese cell more effectively and appear climbing alkali, weeping, circumstances such as short circuit.
Compared with the prior art, the beneficial effects of the utility model reside in that: the utility model discloses a solidification is glued and is filled the interelectrode clearance of positive negative pole of alkali-manganese cell bottom, plays good sealed effect, blocks the inside and external environment contact of battery, prevents moisture and gas exchange, guarantees the sealed effect of battery sealing washer, prevents the weeping, prolongs battery shelf life and performance simultaneously. In addition, the curing adhesive can also prevent short circuit caused by damage (puncture by elastic sheets, springs and the like) of the label paper at the bottom of the battery.
The present invention will be described in further detail with reference to the accompanying drawings and embodiments.
