1. A flow-through rechargeable electrochemical cell comprising:
a container housing a porous cathode comprising a high-porosity cathode base material coated with a cathode active material to form a cathode active material surface and a porous anode comprising a high porosity anode base material coated with an anode active material to form an anode active material surface;
a closed loop fluidly connected to the container;
a fluid electrolyte in the container and closed loop and comprising a working ion;
a pump configured to cause the fluid electrolyte to flow through the closed loop, the porous cathode, and the porous anode during discharge of the electrochemical cell;
wherein a plurality of pores of the porous cathode comprise straight channels with a single cross-sectional geometric shape and have a length equal to the width of the porous cathode in a direction perpendicular to the cross-sectional plane of the plurality of pores of the porous cathode;
wherein a plurality of pores of the porous anode comprise straight channels with a single cross-sectional geometric shape and have a length equal to the width of the porous anode in a direction perpendicular to the cross-sectional plane of the plurality of pores of the porous anode;
wherein flow of the electrolyte through the plurality of pores of the porous cathode and in contact with an electrode is parallel to the cathode active material surface for a length of the plurality of pores of the porous cathode and
wherein flow of the electrolyte through the plurality of pores of the porous anode and in contact with an electrode is parallel to the anode active material surface for a length of the plurality of pores of the porous anode.
