Battery cell, battery device, and electric device

Abstract

The application relates to a battery monomer, a battery device and an electric equipment. The battery monomer comprises a shell with an accommodating cavity in the interior, a liquid injection port communicated with the accommodating cavity is arranged on a first wall of the shell along the thickness direction of the first wall; an electrode assembly is arranged in the accommodating cavity; a lower plastic is arranged between the first wall and the electrode assembly; and a flow guide member is arranged between the lower plastic and the electrode assembly along the thickness direction, the flow guide member has a confluence area and at least one outlet area; the confluence area is used for receiving electrolyte injected from the liquid injection port; each outlet area is arranged on the outer periphery of the confluence area along the circumferential direction of the flow guide member and is communicated with the confluence area and the accommodating cavity located on the outer periphery of the electrode assembly. On one hand, the application can reduce the impact of the electrolyte on the electrode assembly, and on the other hand, the electrolyte is always directed to flow into the bottom of the electrode assembly through each opening, then the electrolyte is soaked from the bottom to the top of the electrode assembly, so that the electrode assembly can be more fully soaked, thereby reducing the probability of lithium precipitation.
