Abstract (en)

[origin: CA3173247A1] A battery (1000) comprising at least one elementary cell (100) formed by an anode (20), an electrolyte (30) and a cathode (50), defining a stack (I), said stack (I) and said battery having six faces, specifically - two mutually opposing front faces (F1, F2), - two mutually opposing side faces (F3, F5), - and two mutually opposing longitudinal faces (F4, F6), it being understood that the first longitudinal face (F6) of the battery comprises at least one anode connection region (1002) and that a second longitudinal face (F4) of the battery comprises at least one cathode connection region (1006), said anode connection region (1002) and cathode connection region (1006) being laterally opposed, characterized in that - in a first longitudinal direction (XX') of the battery, each anode current collector substrate (10) projects simultaneously from each anode layer (20), from each electrolyte material layer (30) or separator layer impregnated with an electrolyte (31), from each cathode layer (50) and from each cathode current collector substrate layer (40) and - in a second longitudinal direction (XX'') of the battery, opposite said first longitudinal direction (XX'), each cathode current collector substrate (40) projects simultaneously from each anode layer (20), from each electrolyte material layer (30) or separator layer impregnated with an electrolyte (31), from each cathode layer (50) and from each anode current collector substrate layer (10).
