JPS5990367A - Battery having spiral electrode body - Google Patents

Abstract

PURPOSE:To enable a battery having an excellent discharge characteristic to be provided by enabling plate groups to be completely homogeneously wound by winding a positive and a negative plate and separators interposed between these plates around wound cores comprising a pair of asymmetric split take-up pins. CONSTITUTION:Plate groups 1 and 2 are wound around wound cores 4 comprising a pair of asymmetric split take-up pins, so that no stage difference is caused between the plate and a separator 3 at the initial end (A). As a result, a spiral electrode body in which the plate groups 1 and 2 are homogeneously wound can be obtained.

Description

DETAILED DESCRIPTION OF THE INVENTION The present study relates to a t-curve equipped with a spiral conductor, and particularly to the structure of the spiral conductor.

In general, the terminal voltage during discharge of a battery with a spiral '11 rh body is the same as the single contact potential of a flat positive and negative granite plate before being spiralized. The value is lower than the value considering the resistance of the opening. One of the reasons for this is that when the positive and negative plates are spirally wound and the distance between the positive and negative plates becomes uneven, the reaction flow concentrates in some areas, leading to excessive reaction! It can be concluded that as the field becomes larger, the terminal voltage decreases. In order to prevent a drop in terminal voltage during discharge due to winding the positive and negative wires in a spiral, wind them in the opposite direction so that the distance between the wires is not uniform. All you have to do is turn it off once. For that purpose, the state of the beginning of winding of the positive and negative tall becomes baking soda.

This is because the entire winding state of the spiral chamber R is 5-way at the beginning of winding.

Specifically, it is considered that the closer the starting state of winding is to a perfect circle, the more uniform the overall winding state will be.

When winding the base and separator in a spiral,

There is a step in the number and separator, and the state at the beginning of winding is not a perfect circle. Therefore, a tar that winds a group of sheets completely evenly is wound using a round core from a pair of asymmetrical split winding bins. The above-mentioned drawbacks of the conventional method are eliminated by rotating the rotor.

The following is an example of the implementation and its effects.
;-Tro.

When winding the +E, negative negative plate and the separator inserted between these plates in a spiral, the state at the beginning of the winding cannot be perfectly circular. However, by winding the moving plate around the length using a winding core consisting of a pair of asymmetrical split winding bins according to the present invention, the moving plate and the separator begin to have a step at the beginning of winding (A in Figure 2). The state becomes closer to a perfect circle. In other words, using the winding core according to the present invention, it is possible to obtain a spiral electric body that is more uniformly wound than that using a conventional winding core, and the electric body can be improved by λ and IIh. You can expect improvements in battery performance.

The shape of the winding core of the present invention used for uniformly winding the melting plate can be any shape as long as it is composed of a pair of asymmetrical split winding bins, and is limited to a pair of arcuate shapes such as No. 2N. Instead of a single fan, it may be a pair of fan shapes.

Using a nickel-cadmium battery as a battery with a spiral electric body, the effectiveness of the present invention was demonstrated.

From Figure i3, it can be seen that the battery 4 according to the present invention has more discharge type 1 than the conventional battery (uniform type I), and the discharge type 1 has more discharge type 1.

As described above, Akira Kizumi's method of creating a spiral electric body can provide a battery with superior performance compared to conventional methods, and its industrial value is great.
