Abstract: Systems, apparatuses, and/or the like are provided. In some embodiments, an electrochemical cell may include a container, a ring-shaped cathode disposed within the container, wherein the ring-shaped cathode defines an open interior, an anode disposed within the open interior of the ring-shaped cathode, a separator disposed between the cathode and the anode, an electrolyte solution, and a current collector electrically connected with a portion of the container, wherein the current collector is positioned at least partially within the anode. For example, current collectors may include a base including a first material that is fixedly attached to the portion of the container and a zinc component composed of a second material and fixedly attached to the base.
