いた。[Problems to be Solved by the Invention] As described above, in this battery, the electrolyte is normally circulated through the heating heat exchanger during discharging, so a dedicated pump for this purpose is required, or a pump as shown in Fig. 4 is required. Even when the electrolyte pump (17) is used for the same purpose, the power consumption is large, reducing the overall battery efficiency.

However, even in such a case, the storage capacity of chlorine in the storage tank (3) can be made sufficiently large, and it is possible to configure one storage tank (3) to cover a plurality of battery units. Therefore, 1 in storage tank (3)
Measures are taken to improve heat exchange efficiency by circulating electrolyte from the plurality of electrolyte tanks (1) to the heating heat exchanger (26) of the stand. However, when the electrolytes of multiple electrodes come into contact and mix in this way, the potentials of these electrolytes differ slightly, causing liquid junctions to occur between each electrode, resulting in a decrease in battery capacity. There were also problems.
（課題を解決するための手段）
本発明はこれに鑑み種々検討した結果上記問題をすべて
解決した亜鉛−塩化物電池を開発したものである。(Means for Solving the Problems) In view of this, the present invention has developed a zinc-chloride battery that solves all of the above problems as a result of various studies.

In a battery, chlorine is absorbed into a cooled chlorine-absorbing solvent and stored in a chlorine storage tank, and during discharge, chlorine is generated from the heated chlorine-absorbing solvent and dissolved in the electrolyte in the circulation system. A heat exchanger is installed inside the chlorine-absorbing solvent circulation system, and each heat exchanger is connected with a pipe, and a highly electrically insulating heat medium is sealed inside. The chlorine-absorbing solvent is sometimes heated by circulating a heat medium between these heat exchangers through the pipes.

It is effective to do so.

の経路は省略した。[Function] As shown in Figure 1, an electrolyte tank heat exchanger (hereinafter referred to as the tank heat exchanger) (2) is provided in the electrolyte tank (1), and a circulation system for the chlorine absorption solvent (3) is installed. For example, an internal heat exchanger (5) is provided in the storage tank (4), and these are connected to the pipe (6) (6°
), and a highly electrically insulating heat medium, such as Freon, is sealed inside the tube, and these heat exchangers (2) (
5) The reason why the heat medium circulates between the two is that during discharge, the heat medium is evaporated by the heat of the electrolyte in the tank heat exchanger (2), and passed through one pipe (6°). The internal heat exchanger (5) releases heat to the low-temperature solvent (3), liquefies it, and transfers it to the pipe (6) for use.
This is because the action of heating the solvent (3) is achieved by repeating the process of returning to the tank internal heat exchanger (2) to receive heat and then dissipating the heat in the internal heat exchanger (5). In Figure 1, the refrigerant path for cooling the solvent (3) during charging is omitted.
このとき熱媒体としてはフレオンＲ−２２のような低沸
点の流体を用いるのが良く、ざらに電解液温度である２
５℃以下の沸点をもつものが望ましい。At this time, it is best to use a fluid with a low boiling point such as Freon R-22 as the heat medium, which is approximately the temperature of the electrolyte 2.
It is desirable to have a boiling point of 5°C or less.
また熱媒体としては電気的に絶縁物を用いることにより

熱用の熱交換器（第１図では内部熱交換器（５）を指す
）との間の管路同士を連結すれば良い。In addition, by using an electrically insulating material as a heat medium, there is no problem of electrolytic corrosion of heat exchangers and conduits, and even when multiple battery units are connected in parallel, there is a gap between each electrode unit. No liquid junction occurs through the heat medium. In this case, when metal materials are used for the heat exchanger, conduits, etc., the heat exchanger in each electrolyte tank due to the potential difference between the heat exchanger materials in each tank will be affected as shown in Figure 1. The material of the pipe line (6) (6°) immediately after the exchanger (2) is electrically insulated pipe (8) (
8'), and the pipes between the pipes (8) (8') and a heat exchanger for heating the solvent (internal heat exchanger (5) is shown in FIG. 1) may be connected to each other.
また熱交換器の材質としては特に塩素に対して耐食性の
高いものが望ましく、例えばチタン。The material for the heat exchanger is preferably one that has high corrosion resistance against chlorine, such as titanium.
タンタル又はテフロン等のフッ素樹脂等を使用するのが

器に入り液化する動作を繰り返す利点がある。Furthermore, if the above-mentioned heat medium is used in a closed circulation system and the heat exchanger in the storage tank is installed at a higher location than the heat exchanger in the electrolyte tank, external power can be added to circulate the heat medium. At the very least, the heat medium liquid liquefied in the heat exchanger in the storage tank naturally flows down to the heat exchanger in the electrolyte tank with low potential energy, evaporates, gasifies again, and returns to the heat exchanger in the storage tank. It has the advantage of repeating the action of entering and liquefying.

交換器の位置関係は自由に選択できる特徴がある。Furthermore, by installing a pump in the pipeline, the positional relationship of each heat exchanger can be freely selected.

３）を加熱して塩素を発生させた。Example (2) As shown in Fig. 3, a heat medium circulation pump (24) is installed in the pipe line (6) (6°) connecting the internal heat exchanger (2) and the external heat exchanger (11). A zinc-chloride battery was fabricated with the same mounting () and other configurations as in Example (1). When operating this battery and discharging, close the refrigerant switching valves (15) (15').
Fully open the heat medium switching valve (16) (16°),
Freon R-2 is operated by operating the heat medium circulation pump (24).
2 is forcibly circulated, and the solvent (
3) was heated to generate chlorine.
一方充電時には熱媒体切換バルブ（１６） （１Ｂ°）
を全開、冷媒切換バルブ（１５）（１５°）を全開とし
、熱媒体循環ポンプ（２４）を停止し、冷凍機（１３）

て塩素を吸収させた。この場合熱媒体循環ポンプ（２４
）を使用しているので両前交換器（２）（１１）の位置
関係は自由である。On the other hand, when charging, the heat medium switching valve (16) (1B°)
fully open, refrigerant switching valve (15) (15°) fully open, heat medium circulation pump (24) stopped, and refrigerator (13)
was operated to cool the solvent (3) in the external heat exchanger (11) and absorb chlorine. In this case, the heat medium circulation pump (24
), the positional relationship between both front exchangers (2) and (11) is free.
上記実施例（１）及び実施例（２）のいずれの場合にお
いても放電時に外部熱交換器（１１）により溶剤（３）
を効果的に加熱できるので該溶剤からの塩素ガスの発生
が効率良く行なわれた。In both of the above embodiments (1) and (2), the solvent (3) is removed by the external heat exchanger (11) during discharge.
Since the solvent can be heated effectively, chlorine gas can be efficiently generated from the solvent.
なお上記いずれの場合も管路（６）（６°）には−部に
フッ素樹脂絶縁管（１２）（１２°）を用いているので
電池部を複数設ける場合にも各槽内熱交換器は互いに電
気的に絶縁されるので、液絡の問題は発生しない。In any of the above cases, the fluororesin insulated tube (12) (12°) is used at the negative part of the pipe line (6) (6°), so even when multiple battery sections are provided, each tank heat exchanger are electrically isolated from each other, so no liquid junction problem occurs.
このように本発明によれば補機消費動力が小ざくなり、
ざらに液絡の発生もないので電池効率が向上し、また構
成部材の電食による損傷もない等顕著な効果を秦するも
のである。In this way, according to the present invention, the power consumption of auxiliary equipment is reduced,
Since there is no occurrence of liquid junctions, the battery efficiency is improved, and there is no damage to the structural members due to electrolytic corrosion.
