Pouch cell and energy consumption device

Abstract

Pouch cell, characterized in that it comprises: an upper housing (1) comprising a first receiving groove (110) and a first crimped edge (120), wherein the first crimped edge (120) is connected to an outer circumference of the first receiving groove (110); a lower housing (2) comprising a second receiving groove (210) and a second crimped edge (220), wherein the second crimped edge (220) is connected to an outer circumference of the second receiving groove (210), wherein the upper housing (1) and the lower housing (2) are joined together such that the first receiving groove (110) and the second receiving groove (210) together enclose a receiving chamber (101); wherein the first crimped edge (120) and the second crimped edge (220) are at least partially opposite each other and are sealed together; a cell (3) arranged in the receiving chamber (101);wherein the upper housing (1) and the lower housing (2) comprise an inner insulating layer, a middle metal layer and an outer protective layer, the inner insulating layer being arranged near the cell (3), the middle metal layer being arranged between the inner insulating layer and the outer protective layer; wherein the first receiving groove (110) has a first main region (111) and a first secondary region (112), the first main region (111) and the first secondary region (112) being arranged at opposite ends of the first receiving groove (110) in a longitudinal direction, the depth of the first main region (111) being H1, while the depth of the first secondary region (112) being h1;wherein the second receiving groove (210) has a second main region (211) and a second secondary region (212), wherein the second main region (211) and the second secondary region (212) are each arranged at two ends of the second receiving groove (210) in the longitudinal direction, wherein a depth of the second main region (211) is H2, while a depth of the second secondary region (212) is h2; where H1, h1, H2 and h2 are specified in millimeters; where |H1-h1| is less than or equal to 0.8 mm; and / or where |H2-h2| is less than or equal to 0.8 mm.;
