Claim 0:
1. A battery, comprising:
a plurality of first battery cells, each first battery cell being provided with a first pressure relief mechanism configured to be actuated when internal pressure or temperature of the first battery cell reaches a threshold, to release the internal pressure of the first battery cell;
a plurality of second battery cells, each second battery cell being provided with a second pressure relief mechanism configured to be actuated when internal pressure or temperature of the second battery cell reaches a threshold, to release the internal pressure of the second battery cell, the plurality of first battery cells and the plurality of second battery cells being arranged alternately along a first direction;
a first discharge channel in a bottom wall of the battery and extending along the first direction, the first discharge channel being closer to a first side of the bottom wall than to a second side of the bottom wall that is opposite to the first side, and the plurality of first pressure relief mechanisms being disposed facing the first discharge channel in a second direction perpendicular to the first direction; and
a second discharge channel in the bottom wall of the battery and extending along the first direction, the second discharge channel being closer to the second side of the bottom wall than to the first side of the bottom wall, and the plurality of second pressure relief mechanisms being disposed facing the second discharge channel in the second direction;
wherein
an energy density of the first battery cell is greater than an energy density of the second battery cell, and an area of the first pressure relief mechanism is greater than an area of the second pressure relief mechanism; and
the first discharge channel is not connected to the second discharge channel.
