Abstract: Provided are a winding shaft, a cell manufacturing apparatus, and a cell manufacturing method. The winding shaft is used for winding plates and includes: a winding shaft body including a first winding surface; an adjustment member configured to be mounted to the winding shaft body and movable simultaneously in an axial direction of the winding shaft and in a radial direction of the winding shaft, where the adjustment member includes a second winding surface, and the first winding surface and the second winding surface are configured to wind the plates jointly; and an actuator configured to drive the adjustment member to move to change a relative position of the second winding surface with respect to the first winding surface, so as to change a winding circumference of the winding shaft. The winding shaft of the present application can reduce the possibility of or the amount of misalignment between the tabs.

Abstract: Provided are an electrode assembly, a battery cell, a battery, and a power consuming device. The electrode assembly includes: a cathode electrode plate, an anode electrode plate, and a separator, the separator being configured to isolate the cathode electrode plate from the anode electrode plate; and an electrolyte adsorption layer configured to be arranged along a surface of at least one of the cathode electrode plate, the anode electrode plate and the separator, wherein the electrolyte adsorption layer is provided with ion exchange channels, which are through holes provided in a thickness direction of the electrolyte adsorption layer. According to the technical solution described above, the electrolyte adsorption layer, which is arranged on the surface of at least one of the cathode electrode plate, the anode electrode plate and the separator, can adsorb and retain an electrolyte.
