Zinc bromine cell having enclosed electrodes

A zinc bromide electrochemical cell comprising:

• an anode assembly comprising:
• an anode pouch comprising:
• a first insulating microporous membrane, and
• an anode being enclosed in the anode pouch, the anode comprising:
• a first electrically conductive anode plate, and
• a second electrically conductive anode plate opposite the first electrically conductive anode plate, the first electrically conductive anode plate and the second electrically conductive anode plate being configured to be plated with zinc,
• a cathode assembly comprising:
• a cathode pouch comprising:
• a second insulating microporous membrane, and
• a cathode being enclosed in the cathode pouch, the cathode comprising:
• a first electrically conductive cathode plate, and
• a second electrically conductive cathode plate opposite the first electrically conductive cathode plate, the first electrically conductive cathode plate and the second electrically conductive cathode plate being configured to facilitate bromine redox reaction, and
• a container comprising:
• an aqueous electrolyte,
• wherein the anode assembly and the cathode assembly are immersed in the aqueous electrolyte.
