Summary of the invention
The utility model solves general core strueture in prior art not have effectively to solve a little less than loaded current ability and the problem of extraction electrode inconvenience, by the combined innovation of battery core main body, positive plate and negative plate, provide a kind of simple in structure, cost is low, production efficiency is high, assembling and extraction electrode are convenient, the battery core reshaping structure that loaded current ability is strong.
In order to solve the technical problem of above-mentioned existence, the utility model is taked following technical proposals: a kind of battery core reshaping structure, comprise aluminium foil and insulation film, it is characterized in that, the middle part of described aluminium foil is provided with carbon dust district, and the size in insulation film and carbon dust district is suitable, the two ends of described aluminium foil are respectively positive terminal and negative pole end, aluminium foil and insulation film are reeled and are formed cylindrical battery core, and described positive terminal is shaped as planar structure, and described negative pole end is shaped as the lug of multiple projections.
In the time making, first carbon dust is coated in to the middle part of aluminium foil, again insulation film is attached on the carbon dust region of aluminium foil, then aluminium foil is reeled together with insulation film, form cylindrical battery core, finally by shaping process, positive terminal is formed to planar structure, negative pole end forms the lug of multiple projections, has just completed.Carbon dust, strengthens the conductive capability of aluminium foil and the surface area of increase aluminium foil, enhances product performance; The planar structure of positive terminal, simple in structure, convenient for production, loaded current ability is strong; The protruding lug of negative pole end, extraction electrode is convenient, is also conducive to electrolyte permeability battery core.
As preferably, described lug is kidney-shaped structure.The lug of kidney-shaped structure, simple in structure, easy to make.
As preferably, the quantity of described lug is 4.Certain many lug quantity, can draw multiple electrodes, is also conducive to electrolyte permeability battery core main body, in the time of battery core and the assembling of battery core shell, plays the effect of location simultaneously, at one stroke multiplex.
As preferably, described positive terminal is punch forming structure.Sheet Metal Forming Technology is simple, facilitates positive plate mass production, and production efficiency is high, and cost is low.
As preferably, described negative pole end is punch forming structure.Facilitate negative plate mass production, production efficiency is high, and cost is low.
As preferably, the edge of described positive terminal and negative pole end is equipped with rounding arc.Positive/negative plate fall arc structure, reduce the diameter at battery core two ends, facilitate the assembling of battery core main body and battery core shell.
Owing to taking above-mentioned technical scheme, a kind of battery core reshaping structure that the utility model provides has such beneficial effect: by the combined innovation of aluminium foil and insulation film and structure thereof, provide a kind of simple in structure, cost is low, production efficiency is high, good product performance, assembling and extraction electrode are convenient, the battery core reshaping structure that loaded current ability is strong.
