Abstract
The utility model discloses a column type battery, which comprises a shell body, a cover body, an electric core, electrolyte and a supporting sleeve. The shell body is in a column shape; the supporting sleeve is in a truncated cone shape with an opening arranged at the top. A containing cavity is formed between the supporting sleeve and the shell body. The electric core and the electrolyte are positioned in the containing cavity. The cover body is arranged at the upper part of the supporting sleeve. The utility model causes the processing technique of the column type battery to be simpler through utilizing the supporting sleeve. The step of manufacturing an annular groove is omitted and the cost is reduced. In addition, through the plane support of the supporting sleeve, the seal of the column type battery cover body of the utility model is more convenient and reliable, and the security performance is better. Moreover, the effective utilizing space of the battery containing cavity is increased, and the ratio of the volume to the capacitance is higher.
Description
Technical field
The utility model relates to and is used for directly changing the device that chemical energy is an electric energy, particularly a kind of cylindrical battery.
Background technology
Cylindrical battery is a kind of common battery, all is widely used at primary cell and secondary cell field.At present common cylindrical battery needs for sealing, all needs at the prefabricated annular ditch groove in battery container edge.It is very high to manufacturing technique requirent to make annular ditch groove, and then has improved battery cost, and this ring-like groove has also taken the intracavity space of battery simultaneously, makes battery volume and capacity ratio step-down, and this is more obvious in the small size cylindrical battery.
Summary of the invention
The utility model is exactly in order to overcome above deficiency, and it is low and can improve the cylindrical battery that the battery intracavity space utilizes to have proposed a kind of cost.
Technical problem of the present utility model is solved by following technical scheme: a kind of cylindrical battery, comprise housing, lid, electric core, electrolyte, described housing is cylindrical, also comprise support set, described support set is round table-like, and its top is provided with opening, is formed with host cavity between described support set and the housing, described electric core and electrolyte level are in described host cavity, and described lid is positioned at the support set top.
Preferably, the external diameter of described support set is identical with described housing internal diameter.
Also comprise the insulated ring between lid and housing.
Described cylindrical battery satisfies following formula: h1+h2=h3, and h1 is the height of described support set in the formula, and h2 is the thickness of described insulated ring, and h3 is the height of described housing.
Described electric core comprises positive pole ear and negative lug, and described positive pole ear and lid connect, and described negative lug and housing connect.
Described electric core comprises positive pole, barrier film and negative pole, and described positive pole, barrier film and negative pole are through reeling or being stacked to cross section shape adapting with described housing and lid.
The beneficial effect that the utility model is compared with the prior art is:
Cylindrical battery of the present utility model is compared with existing cylindrical battery, and is simpler by the production technology that can make cylindrical battery of using support set, saved the step of making annular ditch groove, reduced cost.Cylindrical battery lid of the present utility model in addition is by the planar support of support set, make driving fit more convenient reliable, security performance is better, and the space that effectively utilizes in battery container chamber is increased, volume and capacity ratio is higher, and these beneficial effects are especially obvious in the small size cylindrical battery.
Description of drawings
Fig. 1 is a cylindrical batteries schematic diagram of the present utility model;
Fig. 2 is the structural representation of support set of the present utility model;
