Abstract
The utility model relates to the technical field of rechargeable batteries, in particular to a rechargeable battery with the outer shell surface plated with copper alloy, which comprises an outer shell and an electrode component fixed in the outer shell for generating power; and the surface of the outer shell is plated with a copper alloy layer, and the outer shell is an iron cylindrical shell. Because the inner wall and the outer wall of the battery shell are plated with copper alloy layers, the battery has the advantages of little inner resistance, low self-discharge and longer service life.
Description
Technical field
The utility model relates to the rechargeable battery technical field, and especially a kind of case surface is treated to the rechargeable battery of copper-beryllium.
Background technology
Along with developing rapidly of electronics industry, the portions of electronics device has been miniaturized and has developed various portable electronic devices thus.Battery is as the supply of electrical energy of portable electronic device, and wherein can recharge and re-use owing to secondary cell, so secondary cell is more higher than primary cell cost efficiency, therefore, the various secondary cells of the high high power capacity of small size are developed and be widely used.
Existing secondary cell is the battery that rechargeable battery mostly is NI-G, ni-mh, zinc-nickel, lithium ion, its case surface is treated to nickel plating, particularly the zinc-nickel cell case surface is handled shortcomings such as resistive is big in the nickel plating existence, self discharge is big, is easy to make battery to scrap fully.
The utility model content
The technical problems to be solved in the utility model is: shortcoming and deficiency in order to solve above-mentioned existence, a kind of rechargeable battery with copper alloy shell is provided, and its internal resistance is little, self discharge is little, has prolonged the useful life of battery.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of rechargeable battery with copper alloy shell, have shell and be fixed in the electrode assemblie that being used in the shell produces electricity, it is characterized in that: the surface of shell be coated with copper alloy layer, because the effect of case surface copper alloy layer makes that the internal resistance of battery is little, self discharge is little.
Further, in order to save material, improve the functioning efficiency of battery, the shell of battery is iron degree cylindrical shell.
The beneficial effects of the utility model are, of the present utility model have copper alloy askew rechargeable battery, be coated with copper alloy layer on inwall by battery case and the outer wall, make that the internal resistance of battery is little, self discharge is little, prolong the life-span of its use.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the overall structure upward view of Fig. 1.
Among the figure 1, shell, 2, copper alloy layer.
Embodiment
In conjunction with the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
The rechargeable battery with copper layer shell of preferred forms as shown in Figure 1 and Figure 2 has shell 1 and is fixed in the electrode assemblie that being used in the shell 1 produces electricity, the surface of shell 1 be coated with copper alloy layer 2, shell 1 is iron degree cylindrical shell.
Rechargeable battery of the present utility model is made the shell 1 of cylindricality earlier with iron, on each surface of shell 1, plate layer of copper then, carry out manufacturing, the assembling of electrode assemblie etc. then according to the technology of routine, thereby form the rechargeable battery that internal resistance is little, self discharge is little, and the use of this rechargeable battery prolonged greatly than life-span of general nickel plating battery.
