Anode side sealing for battery cells having porous ceramic layers

An anode assembly for a battery cell, comprising:

• a separator layer substantially free of pores;
• an anode layer at least partially disposed on the separator layer and having a first surface facing the separator layer, a second surface facing away from the separator layer, and an outer surface extending from the first surface to the second surface, wherein the anode layer comprises a solid-state electrolyte (SSE) having pores;
• an anode current collector coupled to the second surface of the anode layer;
• and
• a seal at least partially disposed on the outer surface of the anode layer and comprising a sealant material, wherein the seal is substantially impervious to liquid.

A battery cell, comprising:

• a separator layer substantially free of pores and having a front surface, a back surface spaced from the front surface, and an outer surface extending from the front surface to the back surface;
• an anode layer at least partially disposed on the front surface of the separator layer and having a first surface facing the separator layer, a second surface facing away from the separator layer, and an outer surface extending from the first surface to the second surface, wherein the anode layer comprises a solid-state electrolyte (SSE) having pores;
• an anode current collector coupled to the second surface of the anode layer;
• a cathode layer at least partially disposed on the back surface of the separator layer and having a first surface facing the separator layer, a second surface facing away from the separator layer, and an outer surface extending from the first surface to the second surface;
• a cathode current collector coupled to the second surface of the cathode layer;
• and
• a seal at least partially disposed on the outer surface of the anode layer and comprising a sealant material, wherein the seal is substantially impervious to liquid.

A method of forming an anode assembly, comprising:

• (a) providing:
• a separator layer substantially free of pores,
• an anode layer at least partially disposed on the separator layer and having a first surface facing the separator layer, a second surface facing away from the separator layer, and an outer surface extending from the first surface to the second surface, wherein the anode layer comprises a solid-state electrolyte (SSE) having pores, and
• an anode current collector coupled to the second surface of the anode layer;
• and
• (b) forming a seal at least partially on the outer surface of the anode layer, wherein the seal is substantially impervious to liquid.
