Description
Technical field
The utility model relates to battery manufacture field, particularly a kind of lithium manganese pin type battery.
Background technology
First lithium-manganese cell is succeeded in developing in Japan for 1975, has developed into the lithium battery that existing market is most widely used, output is maximum, is the battery kind that in lithium series primary cell, price is minimum, fail safe is best.Current known lithium-manganese cell is the primary cell of the charge types such as cylindrical, button, flexible package.
Demand to lithium-manganese cell on market increases increasingly, and the assembling of existing lithium-manganese cell is by manual manufacture, because the volume of lithium manganese pin type battery is little, and pure manual production, quite difficulty of current technological operation, efficiency is low; And the capacity of this lithium manganese pin type battery is also quite little, want to increase its capacity, need to increase the content of positive and negative electrode active material (MnO2 & Li), but the content of existing technique positive active material MnO2 is difficult to increase, if increase positive plate density or reduce polytetrafluoroethylene additives ratio, operator all easily ftractures in the time of bundle volume positive plate, causes producing.In addition, the equal defectiveness in the aspect such as anti-leakage and storge quality of existing lithium manganese pin type battery.
Utility model content
The purpose of this utility model is the above-mentioned defect for prior art, and a kind of simple in structure, easy to assembly, production cost is low, battery capacity is large lithium manganese pin type battery is provided.
For solving the above-mentioned defect of prior art, technical scheme to be solved in the utility model is: a kind of lithium manganese pin type battery, comprise a cylindrical cell external case and negative pole contact rod, one end of described battery case is provided with an opening, in the cavity of described battery case, be provided with at least one positive powder ring, one end of described negative pole contact rod is stretched to by described opening in the cavity of described battery case, and volume has one deck lithium lamella, outer surface volume at described lithium lamella has one deck membrane layer, in the cavity of described battery case, be marked with electrolyte, described opening part is provided with a leakage proof rubber plug, the upper end of described battery case is provided with a draw-in groove.
One as the utility model lithium manganese pin type battery is improved, and described positive powder ring is made up of manganese dioxide, graphite, acetylene black, polytetrafluoroethylene.
Compared with prior art, the utility model has the advantages that: the utility model is directly pressed into the positive powder ring preparing in battery case, this positive pole assembly process need to not carry out under the dry environments such as glove box, in dry environment, only the negative pole contact rod of rolling up negative pole and barrier film need be inserted in positive powder ring; The operation that is pressed into powder ring is pressed in batches by work piece holder, once can assemble more than 100, simple, convenient, has avoided the drawback of traditional positive plate employing winding method, greatly improves the production efficiency of lithium manganese pin type battery; Because adopting powder ring, positive pole enters anode cover, but not positive plate coiling form, positive powder ring density can increase substantially, and the consumption of polytetrafluoroethylene can greatly reduce, and increases positive active material manganese dioxide, thereby increases the capacitance of battery.The present invention is simple to operate, be not subject to personnel and environmental limit, and greatly having improved production efficiency and battery capacity increases.The utility model is mainly used in the luminous energy of buoy on fishing rod, also can be for the power supply function of lighting rod, golf, luminescent and acoustic device, toy, small-sized light-emitting device etc.
