Abstract (en)
[origin: CA3162508A1] Said battery comprises a stack (I) alternating between at least one anode (20) and at least one cathode (50), an encapsulating system which is referred to as the primary encapsulating system (1020) and covers four of the six faces of the stack (I), at least one anode contact member (1040) capable of ensuring electrical contact between the stack and an external conductive element, and at least one cathode contact member (1050) capable of ensuring electrical contact between the stack and an external conductive element. According to the invention, the battery also comprises an encapsulating system referred to as the additional encapsulating system (1030), said additional encapsulating system comprising two front regions (1031, 1032), each of which covers a respective front region (1021, 1022) of the primary encapsulating system, and two side regions (1033, 1035), each of which covers a respective side region (1023, 1025), which is free of any contact member, of the primary encapsulating system, each of the two front regions (1031, 1032) of the additional encapsulating system (1030) also covering the front ends (1041, 1042, 1051, 1052) of the anode contact members and the cathode contact members, respectively, and each of the front regions (1031, 1032) of the additional encapsulating system forming a continuous surface with the side regions (1033, 1035) of the additional encapsulating system.
