A solid-state electrochemical cell is provided including a first electrode connected to a first current collector, a second electrode connected to a second current collector, a separator interconnecting the first electrode and the second electrode, the separator including a solid-state electrolyte, first oriented pores including a first electrode material formed in the first electrode, and second oriented pores including a second electrode material formed in the second electrode, wherein at least one of the first oriented pores and the second oriented pores includes an electronically conducting network extending on sidewall surfaces thereof from a corresponding one of the first and second current collectors to the electrolyte separator. The second electrode includes a filling aperture including a seal configured to isolate the first electrode from cathode material in the second electrode.
