Abstract
The utility model discloses a column-shaped battery case, which comprises an inner battery case and an outer battery case. The column-shaped battery case is characterized in that the inner battery case and the outer battery case are connected through a connecting post at the bottom parts thereof, the connecting post is arranged at the bottom parts of the inner battery case and the outer battery case, and a heat insulating layer is arranged between the inner battery case and the outer battery case. The inner battery case and the outer battery case are cylindrical bodies made of concentric columnar steel or nick plating steel material. The steel or stainless steel connecting post is arranged at the bottom parts of the inner battery case and the outer battery case, and is integrated therewith through laser welding or spot welding. The heat insulating layer between the inner battery case and the outer battery case is made of asbestos fiber, polyfluoroethylene non-woven fabric or polyvinyl chloride foam. The upper edges of the inner battery case and the outer battery case are welded together. A battery made of the battery case provided by the utility model by adopting the above technical scheme can work normally under extremely high or low ambient temperature conditions.
Description
Technical field
The utility model relates to battery and makes the field, more specifically relates to a kind of cylindrical battery shell, can be used for making various types of once, the secondary circle cylindrical battery.
Background technology
At present, the cylindrical battery shell of existing industry is generally the individual layer battery case of nickel plating steel or stainless steel.Battery by the manufacturing of individual layer battery case, the invar mass shell has good heat-conducting, battery is easy to reach approximate consistent or identical with ambient temperature under high and low temperature environment, thereby make battery operating state under high temperature (being higher than 60 ℃) or low temperature (being lower than-40 ℃) condition extremely unstable, perhaps because the extremely low accident such as can't work fully or blast of ambient temperature owing to temperature is higher.Therefore, existing battery can only be worked under conventional temperature conditions mostly, and can't operate as normal under higher temperature or lower extreme conditions such as temperature, even blasts or lost efficacy.
Summary of the invention
In order to solve the problem that above-mentioned prior art exists, the purpose of this utility model is to be to provide a kind of cylindrical battery shell, and the battery that the utility model battery case is produced can operate as normal under higher (being higher than 120 ℃) or lower extreme ambient temperature conditions such as (being lower than-60 ℃).
The utility model is achieved by following technical proposals: a kind of cylindrical battery shell, described cylindrical battery shell comprise that the joint pin 3 of battery case 2, nickel plating steel or stainless steel of battery inner casing 1, nickel plating steel or stainless steel of nickel plating steel or stainless steel and insulation material layer 4 etc. partly form.
Further, the utility model comprises following content:
Described a kind of cylindrical battery shell, battery inner casing, battery case are formed, it is characterized in that, described battery case is by four parts: battery inner casing, battery case, battery inner casing link to each other with the joint pin of battery case by the bottom, the joint pin of battery inner casing and battery case bottom and be filled between battery inner casing, the battery case heat insulation layer is arranged.
Described a kind of cylindrical battery shell is characterized in that: described battery inner casing, battery case are that concentric column steel or nickel-plated steel material are made the cylinder formation.
Described a kind of cylindrical battery shell, it is characterized in that: described battery inner casing and battery case bottom becomes one by between the joint pin of steel or stainless steel and the inside and outside shell bottom by laser fusion welding or spot welding, and joint pin plays and conducts electricity and supporting role.
Described a kind of cylindrical battery shell is characterized in that: the heat insulation layer between described battery inner casing, the battery case is asbestos fibre, polytetrafluoroethylene nonwoven fabrics or polyvinyl chloride foam.
Described a kind of cylindrical battery shell is characterized in that: described battery inner casing, battery case top edge are welded as a whole.
Adopt the technical solution of the utility model, can obtain following obvious effects: with the battery of a kind of cylindrical battery shell production of technical solutions of the utility model, owing to adopt insulation, bilayer cells shell, bilayer cells shell bottom has one to support conductive pole connection ectonexine battery case, this heat-barrier material is filled at other positions, thereby solves safety problem such as cisco unity malfunction or inefficacy or blast under the battery extreme temperature environmental condition effectively.
The utility model is applicable to the cylindrical battery of all kinds, various models.

Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model patent is described in further detail.
Shown in Figure 3 as Fig. 1, Fig. 2 A, Fig. 2 B, Fig. 2 C, be the profile of a kind of cylindrical battery shell of the utility model specific embodiment.The utility model is a kind of cylindrical battery shell, and this battery case is by four parts: battery inner casing 1 (Fig. 2 a), the joint pin 3 (Fig. 3) of battery case 2 (Fig. 2 b), battery inner casing 1 and battery case 2 bottoms and be filled in the heat insulation layer 4 that has between the inside and outside battery case.Battery inner casing 1, battery case 2 are that concentric column steel or nickel-plated steel material are made the cylinder formation; Battery inner casing 1 and battery case 2 bottoms are by becoming one by spot welding or one-step casting between the joint pin 3 of steel or stainless steel and the inside and outside shell bottom; Heat insulation layer 4 between battery inner casing 1, the battery case 2 is asbestos fibre, polytetrafluoroethylene nonwoven fabrics or polyvinyl chloride foam; It is one that battery inner casing 1, battery case 2 top edge adopt laser welding.
Yet the above is a preferred embodiment of the present utility model only, is not so limits to scope of the present utility model, and equivalences that all utilization the utility model description are carried out change, and all are included in equally in the scope of the present utility model.
