Description
SPECIFICATION
Elliptical column type non-aqueous electrolyte battery
The present invention is concerned with an elliptical column type, non-aqueous electrolyte battery provided with an elliptical column type spiral electrode assembly.
Recently, with rapid technical progress in various kinds of electronic equipment and appliances, batteries have been employed as their power sources. Among these equipment and appliances, comparatively high current has been especially required in the fields of, for example, radio receivers, tape recorders and cameras. In spite of small appliances, for example, two or four cylindrical type alkaline manganese batteries (battery voltage: 1.5 V) have been used as a 3 V- or 6 V-battery by connecting them in series with one another.
As shown by way of example in Fig. 5 of the accompanying drawings, two alkaline manganese batteries (20) are arranged in parallel so that positive and negative terminals (21) and (22) are positioned at one end surface and are placed in a space for batteries in an appliance (30), which includes positive and negative contact strips (31) and (32), respectively.
Recently, lithium non-aqueous electrolyte batteries, which include a negative-active material of lithium and a positive-active material of, for example, manganese dioxide, carbon fluoride or silver chromate, have been used in practice. Such batteries have attracted attention because the battery voltage is 3 V, which is about twice as high as that of the usual alkaline manganese batteries or manganese dry batteries and because such batteries have a high energy density.
We have found the described features of the non-aqueous electrolyte battery and have disclosed the non-aqueous electrolyte battery in our copending Japanese Patent Application
No. 49665/1981, which is used instead of arranging two cylindrical type alkaline manganese batteries or manganese dry batteries in parallel. The battery is one which includes an elliptically cylindrical casing which accommodates an elliptical column type spiral electrode assembly formed by winding positive and negative electrode plates through a separator.
The elliptical column type serial electrode assembly is especially provided by winding the electrode group around a plate-shaped core.
The present invention further improves the elliptical column type, non-aqueous battery described above and the object of the present invention is to improve the battery characteristics by lowering the internal resistance.
Thus, according to the present invention, there is provided an elliptical column type, non-aqueous electrolyte battery, comprising an elliptical column type spiral electrode assembly formed by winding positive and negative electrode plates through a separator and a resilient member positioned in the centre of the electrode assembly and normally expanding the electrode assembly from the centre in outward directions of larger and smaller radius portions.
According to the present invention, one battery is not used instead of obtaining high current by employing two cylindrical batteries arranged in parallel as shown in known manner but also the adhesion of the positive electrode plate to the negative electrode plate through the separator is increased by the resilient member located at the centre of the electrode assembly. As a result, the internal resistance is reduced to improve the battery characteristics.
For a better understanding of the present invention, reference is made to the accompanying drawings, in which:
Figure 1 is a vertical sectional view of a battery according to one embodiment of the present invention;
Figure 2 is a cross-sectional view of the battery taken along the line A-A' in Fig. 1;
Figure 3 is a perspective view of the resilient member (11) in Figs. 1 and 2;
Figure 4 is a perspective view of another resilient member (11'); and
Figure 5 is a view showing two cylindrical type conventional batteries arranged in parallel and located in a space for batteries in an electronic appliance.
The electrode assembly used for the nonaqueous electrolyte battery according to the present invention includes an elliptical column type electrode assembly which is provided by spirally winding belt-shaped negative and positive electrode plates through a belt-shaped separator. The larger radius portion is about twice as large in size as the smaller radius portion.
The resilient member used for the nonaqueous electrolyte battery according to the present invention is made of, for example, a conductive metal plate, such as stainless steel, and is positioned at the centre of the elliptical column type electrode assembly to expand it from the centre in directions of larger and smaller radius portions. The structure of the elliptical resilient member is as follows: 1 ) a gap continuous from one open end to the other is provided in the side walls, as shown in Fig. 3 and 2) one end, cut from one open end to the other, is bent so as to give a Ushaped recessed portion, the other end being engaged with the U-shaped recessed portion, as shown in Fig. 4.
The present invention will now be described, by way of example, with reference to the illustrated embodiments.
In Figs. 1 and 2, (1) is a stainless steel casing, which is elliptical in cross-section, an
insulating sheet (2) being provided at the bottom. In this case, the elliptical type cylindrical casing is designed in such a manner that the larger radius portion is about twice as large as the smaller radius portion and corresponds approximately to the size obtained when arranging two conventional 1.5 V-cylindrical-type batteries in parallel. (3) is a stainless steel cover plate for enclosing the open portion of the casing (1), the periphery of which is fixed to the open end of the casing by using, for example, laser welding. (4) is a
T-shaped terminal pin, a part of which is inserted through an insulator (5) into a perforation provided in the cover plate (3), the end of which is crimped and secured to a metal ring (6).A negative external terminal plate (7) is secured to the upper surface of a metal ring (6). (8) is an insulating ring for preventing electrical connection between the negative external terminal plate (7) and the cover plate (3). (9) is a positive external terminal cap attached to the cover plate (3) opposite the negative external terminal plate (7). (10) is the elliptical column type spiral electrode assembly which is constituted by spot welding a negative collector net (12'), exposed from one end of a lithium negative electrode plate (12), to an elliptical type conductive resilient member (11) of cylindrical form used as a winding core, superposing a positive electrode plate (14) of manganese dioxide on the negative electrode plate (12) through a separator (13) and winding them around the resilient member.For carrying out the winding, a shaft of a take-up jig is inserted into the centre of the resilient member (11). In this case, the positive electrode plate (14) is positioned at the outermost side of the electrode assembly and the positive collector net (14'), exposed from the positive electrode plate (14), is contacted to the inner surface of the casing (1) so as to be electrically connected. (15) is an insulating sheet arranged on the upper surface of the electrode assembly (10).
In this embodiment, the resilient member (11) located in the central space of the spiral electrode assembly (10) is used as both the winding core in producing the electrode assembly and as the negative collector. One end of a negative lead plate (16), which is secured to the resilient member (11) by spot welding, is fixed to the lower end of the negative terminal pin (4) and is electrically connected thereto. Fig. 4 shows another embodiment of the resilient member (11').
According to the non-aqueous electrolyte battery of the present invention, since the battery is provided with the elliptical column type spiral electrode assembly and the appearance of the shape is of the elliptical column type, the following advantages will be obtained when the battery is used instead of the power supply batteries of electronic equipment and appliances which employ two conventional cylindrical batteries with a battery voltage of 1.5 V arranged in parallel and connected in series with each other as described initially:
a) Since the appearance of the shape is of the elliptical column type, the battery is similar in shape to that of two cylindrical type batteries arranged in parallel and it is thus possible to employ the battery in existing electronic equipment and appliances.In addition, because the battery has a structure such that the electrode assembly can be placed in the space required for two cylindrical type batteries arranged in parallel, the volume efficiency is improved.
b) Although previously care had to be taken that two cylindrical type batteries were arranged in given directions, insertion is simplified in the case of the non-aqueous electrolyte battery of the present invention because it can be used instead of two cylindrical type batteries.
Furthermore, the resilient member is positioned in the central space of the elliptical column type spiral electrode assembly and the electrode assembly (10) is usually expanded outwardly from the centre due to the force of restitution of the resilient member (11), as shown in Fig. 2. Consequently, a good adhesion of the positive electrode plate to the negative electrode plate is obtained and the internal resistance is reduced, thereby improving the battery characteristics.
