BATTERY

A battery according to some implementations includes a first liquid electrode to undergo a first half reaction, a second liquid electrode to undergo a second half reaction, a hollow frame forming a first electrode reservoir to store the first liquid electrode and a second electrode reservoir to store the second liquid electrode, and a separating membrane coupled to the frame and disposed between the first electrode reservoir and the second electrode reservoir, wherein the frame includes an inter-electrode communication part configured to allow the first electrode reservoir and the second electrode reservoir to be in fluidic communication with each other.
