正極電解液を正極室２に導くようにしている。 The positive electrode electrolyte storage tank 14 is equipped with a bypass pipe 26 for branching the positive electrode electrolyte from near the electrolyte inflow side and guiding it to the positive electrode chamber 2. The positive electrode electrolyte is introduced into the positive electrode chamber 2 through a valve 28 in the connected pipe 18 and a valve 30 in the bypass pipe 26 .
このような構成からなる電池においては、充電
時には、以下に示すような電池反応を行つてい
る。 In a battery having such a configuration, the following battery reactions occur during charging.
正極：2Br-→Br2＋2e-
負極：Zn2+＋2e-→Zn
また、正極で発生した臭素は電解液中の臭化錯

The two pumps 22 and 24 are respectively driven to supply the bromide complex generated in the positive electrode plate 10 to the positive electrode electrolyte storage tank 14. At the time of discharge, the valve 28 is opened and the pumps are driven to supply the bromide complex generated in the positive electrode plate 10 to the positive electrode electrolyte storage tank 14. The complex stored in the positive electrode electrolyte storage tank 14 is supplied.

配管内を電解液は流れるが錯化物は流れず電池性
能が低下するという問題が生じた。 The bromine complex generated along with the bromine generated during charging has a specific gravity of 3.0, which is larger than that of an aqueous zinc bromide solution of 1.6. Therefore, when an electrolyte containing a bromine complex is supplied from the cathode electrolyte storage tank 14 into the cathode chamber 6, if the flow rate in the piping is low, the bromine complex will settle and will not be supplied to the electrode plate. . In other words, when the flow rate in the piping was reduced, the electrolytic solution flowed in the positive electrode piping, but the complex did not flow, resulting in a problem that the battery performance deteriorated.

である。E Means for Solving the Problems In the present invention, in order to achieve the above-mentioned object, the inside of the positive electrode chamber and the negative electrode chamber are divided into a positive electrode chamber containing a precise electrode and a negative electrode chamber containing a negative electrode by a microporous membrane. An electrolyte circulating zinc-bromine secondary battery in which a zinc-bromine electrolyte containing a quaternary ammonium salt of bromine as a bromine complexing agent is circulated, and the system further includes an upward passage through which the electrolyte flows upward.

By maintaining the flow velocity at a vertical velocity component exceeding 70 cm/sec, the bromine complex does not settle in the middle of the vertical piping, and is stably supplied to the positive electrode plate along with the flow of the electrolyte. Also, 150cm/
By maintaining the flow rate below sec, the power consumption of the feed pump is reduced.

In the conventional device shown in FIG. 3, a bypass pipe 36 equipped with a flow rate regulating valve 34 was attached to the positive electrode liquid circulation pipe 18. Additionally, a current meter 38 was attached to enable monitoring of the flow rate.

給するようになつている。 In addition, in the figure, the positive electrode liquid circulation pipe 18 is
In order to change the direction of electrolytic solution inflow into the positive electrode chamber 6, a four-way pot 32 is provided in the middle thereof. This is because the bromine complexes generated with the bromine generated during charging are
Since the specific gravity is 3.0, which is larger than 1.6 of the zinc bromide aqueous solution, when filling the positive electrode chamber 6 with electrolyte, it flows from the bottom to the top, and during charging and discharging, it flows into the positive electrode chamber 6 from the top to the bottom. The direction of the flow is switched by a four-way tap 32 at the same time, so that the bromine complex generated during charging is quickly discharged from the positive electrode chamber 6, and the bromine complex is evenly supplied to the positive electrode chamber 6 during discharging. .
装置において、電極面積は800cm2、配管パイプ

直方向距離１ｍ、他の配管内径はφ8mmとした。

級アンモニウム塩を正極、負極各々15とした。 In the apparatus, the electrode area was 800 cm 2 , the inner diameter of the piping 18 was φ20 mm at the positive electrode flow rate measurement piping section, the vertical distance was 1 m, and the other piping inner diameters were φ8 mm.
The electrolyte contained 3 mol/ZnBr 2 and 1 mol/bromine of a quaternary ammonium salt for the positive electrode and the negative electrode, respectively.
臭素の四級アンモニウム塩は、メチルエチルピ
ロリジウムブロマイド、メチルエチルモルホリニ
ウムブロマイドの等モル混合物とした。 The quaternary ammonium salt of bromine was an equimolar mixture of methylethylpyrrolidium bromide and methylethylmorpholinium bromide.

率を算出した。 After charging for 8 hours at a charging/discharging current of 16A, the flow velocity in the vertical direction of the positive electrode pipe was adjusted to 50, 60, 70, 80, 90, respectively using the flow velocity control valve 34 of the bypass pipe.
100, 125, 150cm/sec, discharge end voltage 1V
The discharge time was measured, and the coulombic efficiency was calculated.

れを汲上げるようにした。 In addition, if there is an interval of more than a certain period of time (e.g. 8 hours) after charging until discharging, if the battery is filled with electrolyte while being charged, Br 2 will pass through the microporous membrane separator and reach the negative electrode. It diffuses into the chamber, reacts with deposited metal Zn, and self-discharges. To prevent this, all the electrolyte in the stacked battery (stack of unit batteries) is returned to the tank below after charging, and it is removed during discharge. I tried to pump it up.
第２図にその結果を示した。図に示したよう
に、70cm／sec以下はクーロン効率が30％程度に
対して、70cm／secを越えるとクーロン効果が急
に高くなり、80cm／sec以上では80％以上に上が
つている。 Figure 2 shows the results. As shown in the figure, the Coulombic efficiency is about 30% below 70cm/sec, but the Coulombic effect suddenly increases when it exceeds 70cm/sec, and rises to over 80% above 80cm/sec.
これは、比重の大きい臭素錯化物が、正極電解
液貯蔵タンクから正極室に電解液を汲上げる場
合、70cm／secより大きな流速がなければ、縦方
向配管の途中より沈降し正極室に充分に供給され
ないためである。 This is because when pumping the electrolyte from the cathode electrolyte storage tank to the cathode chamber, bromine complexes with high specific gravity will settle from the middle of the vertical piping and will not reach the cathode chamber sufficiently unless the flow rate is greater than 70 cm/sec. This is because they are not supplied.
従つて、臭素錯化物を電池本体に安定供給する
のに必要な流速は垂直上方成分が70cm／secを越
える流速である。 Therefore, the flow rate required to stably supply the bromine complex to the battery body is a flow rate at which the vertically upward component exceeds 70 cm/sec.
しかし、電池装置全体のエネルギー効率を考え
た場合、ポンプの消費電力が大きくなるほど電池
装置自体のエネルギー効率は低くなるのでむやみ
に流速を速めるのは得策ではなく、70cm／secを
越え、しかも過剰でない流速、つまり第２図によ
ると垂直上方成分流速が100cm／sec程度となる流
速が最も望ましい。 However, when considering the energy efficiency of the entire battery device, the greater the power consumption of the pump, the lower the energy efficiency of the battery device itself, so it is not a good idea to increase the flow rate unnecessarily. The most desirable flow velocity, that is, the flow velocity at which the vertical upward component flow velocity is about 100 cm/sec according to FIG.
この結果に基づき、正極電解液循環ポンプの必
要最小限に選ぶなどの方法で、ポンプの消費電力
を抑えつつ、電池のエネルギー効率を最高にする
ことが期待できる。 Based on these results, it is expected that by selecting the minimum number of cathode electrolyte circulation pumps required, it is possible to maximize the energy efficiency of the battery while minimizing the power consumption of the pumps.

エネルギー効率が高まる。H. Effects of the Invention As described above, according to the present invention, when an electrolyte is supplied from the positive plate tank to the battery body during discharge, the flow velocity in the passage is controlled by its vertically upward component.
Since the flow rate is maintained at a flow rate exceeding 70 cm/sec, supply shortages due to sedimentation of bromine complexes in the upward flow path are eliminated, and a stable discharge effect can be obtained. In addition, by maintaining the flow rate below 150 cm/sec, the power consumption of the supply pump is suppressed and the energy efficiency of the entire battery is increased.
