Abstract: A battery and an electric apparatus are described. The battery includes a firefighting pipe and a plurality of battery cells provided with a pressure relief mechanism. The pressure relief mechanism is configured to be actuated and release internal pressure in a first direction when the internal pressure or temperature of the battery cell reaches a threshold; the firefighting pipe is arranged on a side of the plurality of battery cells that is provided with the pressure relief mechanism, and is disposed in a staggered manner with the pressure relief mechanism; and the firefighting pipe is provided with a drainage opening, where the drainage opening is configured to discharge a firefighting medium toward the pressure relief mechanism when the pressure relief mechanism is actuated, so as to cool the battery cell. The battery allows the firefighting medium to more quickly cool a battery cell, thereby improving safety of the battery.

Abstract: This application discloses a battery cell and a battery pack. The battery cell includes a housing and a bare cell located in an inner cavity of the housing. The bare cell includes at least two opposite extension ends and a middle region located between the two opposite extension ends of the bare cell. The two opposite extension ends of the bare cell are configured to be lower than the middle region of the bare cell in a height direction. The bare cell of this cell forms a structure that is high in the middle and low at edges, and a liquid level height of an electrolyte solution in the housing is below the middle region of the bare cell and above extension ends.

Abstract: An electrode assembly and a manufacturing method therefor, a battery cell, a battery, and a power consuming device are described. The electrode assembly includes: a first electrode plate; a first separator; and a second separator. The second separator and the first separator are located on two opposite sides of the first electrode plate in a thickness direction, and the first separator and the second separator are both turned over and enclose an edge of the first electrode plate that is provided with no tab. On this basis, the safety performance of the battery can be effectively improved.
