後には負極液内に水素発泡がみられた。 This conventional zinc-bromine cell has an electrode area of 1600 cm 2 , a bipolar tank capacity of 900 ml, and a battery for each liquid phase.
Add 796 ml of 3 mol/ZnBr 2 + 1 mol/Q-Br (however, Q-Br is 1 mol of bromine complex), and add 6 with 32A.
Assuming that charging was carried out for an hour, hydrogen bubbling was observed in the negative electrode liquid 5 hours after the start of charging.

The amount of electricity of Zn in 796ml of Q-Br is 0.796×

128Ah, and at 32A, Zn ions in the negative electrode liquid disappear after 4 hours, and when charging is attempted thereafter, hydrogen is generated on the negative electrode. However, in reality, Zn ions in the positive electrode solution diffuse into the negative electrode solution through the diaphragm 4, and this Zn ion supply extends hydrogen bubbling until 5 hours after the start of charging.

ブ１６を操作することにより正極液槽側へ戻す。F Effect In the electrolyte circulation type metal-halogen secondary battery of the present invention shown in FIG. 1 after filling an appropriate amount of electrolyte into the anode solution tank 5 and the cathode solution tank 6, the cathode solution tank 6 is filled when charging. The gist is that the liquid pressure in the positive electrode chamber 3 is made relatively higher than the liquid pressure in the negative electrode chamber 2, and this is done by operating the liquid pump 10 and the valve 14. This is done by In this way, by increasing the pressure of the electrolytic solution on the surface of the diaphragm 4 on the positive electrode chamber 3 side, the electrolytic solution is forced to pass through the diaphragm 4 and move to the negative electrode chamber 2 side.
This allows Zn ions held in the electrolyte in the positive electrode chamber to be sent to the negative electrode chamber, thereby extending the charging time. The increased electrolyte in the negative electrode chamber is returned to the positive electrode tank by operating the valve 16.

極液槽５の電解液量よりも大きくしたこと以外は
第１図と同一である。 In this way, the charging depth becomes high and the energy density is improved. Next, a further example of the configuration of the present invention schematically shown in FIG. 2 will be described. In this configuration, the amount of electrolyte in the positive electrode tank 6 is made larger than the amount of electrolyte in the negative electrode tank 5. is the same as in FIG.
因みに、亜鉛−臭素電池では、充電時に発生し
たBr2が、Ｑ−Br3、Ｑ−Br5等の錯化物の形で正
極液槽中に沈殿し、錯化物にならない正極液中の
Br2の濃度が低い状態に保たれる。また、その錯
化物にならない活性度の高いBr2の濃度は、
比率＝正極液中のBr2量／正極電解液量
（錯化物になつたBr2を含む）
が高くなると、その活性度の高いBr2濃度が高く
なつて負極液側へ隔膜を通して拡散するBr2量が
多くなり、負極面上の析出亜鉛と自己放電を起し
て電気量効率を低下することはよく知られてい
る。また、比率＝正極液中の錯化物／正極電解液
量が高くなると液の電導度が低くなつて電圧効率
を低下させることもよく知られている。 Incidentally, in zinc-bromine batteries, Br 2 generated during charging precipitates in the cathode solution tank in the form of complexes such as Q-Br 3 and Q-Br 5 , and the Br 2 in the cathode solution that does not become complexes.
The concentration of Br2 is kept low. In addition, the concentration of highly active Br 2 that does not form a complex is determined by the ratio = amount of Br 2 in the cathode solution / amount of cathode electrolyte (including Br 2 that becomes a complex). It is well known that as the Br 2 concentration increases, the amount of Br 2 that diffuses through the diaphragm to the negative electrode liquid side increases, causing self-discharge with zinc deposited on the negative electrode surface and reducing the electrical efficiency. It is also well known that when the ratio=complex in the catholyte/amount of cathode electrolyte becomes high, the conductivity of the liquid becomes low and the voltage efficiency is reduced.
このため、隔膜を通つて増加した負極室側の電
解液をバルブ１６を操作することにより正極液槽
側へ戻したり、正極電解液量を負極電解液量より
も増加させたりして、送液管により正極室に送液
される電解液全量を、負極室に送液される電解液
全量よりも多くして、前述の比率を低くすること
によつて電気量効率及び電圧効率の低下を少なく
することが可能である。 Therefore, by operating the valve 16, the electrolyte in the negative electrode chamber that has increased through the diaphragm is returned to the positive electrode tank, or by increasing the amount of positive electrode electrolyte more than the amount of negative electrode electrolyte. By making the total amount of electrolyte sent to the positive electrode chamber by the tube larger than the total amount of electrolyte sent to the negative electrode chamber and lowering the aforementioned ratio, the decrease in electrical quantity efficiency and voltage efficiency can be minimized. It is possible to do so.
