Configurations for battery cell packaging

A battery comprising:

• a battery cell characterized by an L-shaped body defining an interior corner;
• and
• a pouch folded about the battery cell along a length of the battery cell, wherein the pouch defines a seal where a first section of the pouch is sealed to a second section of the pouch externally to the battery cell about each side of the battery cell but the length along which the pouch is folded;
• tape positioned along a first surface of the seal and extending about an outer edge of the seal to a second surface of the seal opposite the first surface, wherein a first corner tape piece is positioned on one side of the seal at the interior corner, and wherein a second corner tape piece is positioned on an opposite side of the seal as the first corner tape piece;
• and
• adhesive disposed on an exterior surface of the tape along a portion of the tape positioned on the second surface of the seal, wherein the adhesive couples the tape and seal with a section of the pouch contacting the battery cell.

A battery comprising:

• a battery cell comprising a longitudinal body section and a lateral body section extending from and normal to the longitudinal body section, wherein an intersection of the longitudinal body section and the lateral body section defines an interior corner, and wherein the battery cell defines the interior corner as an arcuate shape recessed from a planar intersection of a sidewall of the lateral body section and a sidewall of the longitudinal body section;
• a pouch extending about the battery cell, wherein the pouch defines a seal where a first section of the pouch is sealed to a second section of the pouch externally to the battery cell about a plurality of sides of the battery cell including at the interior corner, and wherein the seal is folded against the pouch and coupled with the pouch along multiple sides of the battery cell;
• and
• tape disposed along and folded over an exterior edge of the seal along each side of the plurality of sides of the battery cell along which the seal is formed, wherein the tape comprises a material layer and an adhesive layer, and wherein the adhesive layer of the tape is maintained in contact with the seal of the pouch without extending to a portion of the pouch in contact with the battery cell.
