Abstract: Embodiments of the present application provide an electrode piece, a battery cell and a battery, where the electrode piece includes a current collector, a first material layer, and an active material layer; the first material layer and the active material layer are provided on a surface of the current collector, and the first material layer and the active material layer extend along a length direction of the current collector and are alternately arranged in a width direction of the current collector; where the first material layer includes a first material, and the first material includes an amphiphilic polymer and a structural conductive polymer. The infiltration effect of the electrolyte can be improved, the aging time is shortened, and an injection amount of electrolyte is reduced.

Abstract: A retractable pen including a first barrel, an ink cartridge, a second barrel, a clamping component and a spring; a main body of the ink cartridge, the spring and the clamping component are all located inside the first barrel and the second barrel, the spring is wound on a portion, close to the nib, of the ink cartridge, and the nib in a portion of the ink cartridge can be extended and exposed out of the first barrel; a mounting portion, muff-coupled to the first barrel, is arranged on the clamping component, and the clamping component is rotatable with respect to the first barrel; when the first barrel is muff-coupled to the second barrel, a polygonal neck is formed on a surface where an outer surface of the clamping component comes into contact with the second barrel.

Abstract: The present invention relates to a lift-pull pen, which includes a pen point tube, an outer tube, a refill and a return spring. The pen point tube and the outer tube are nested to form an outer pen shell. The refill is located in the outer pen shell. The return spring is located in the pen point tube and specifically located between a pen point end of the refill and the pen point tube. The pen point tube extends to be provided with one or a plurality of buckle extension bodies and one or a plurality of fixed extension columns extend from the pen point tube.

Abstract: A retractable pen with a push button includes a top plug, a barrel and a bottom holder. The top plug is partially insertable into the barrel and is axially movable with respect to the barrel, and the bottom holder is in threaded connection with the barrel. A refill is arranged in the top plug, the barrel and the bottom holder. A reset spring is arranged between the refill and the bottom holder. An end of the push button located in the barrel is provided with at least one clamping member configured to clamp the barrel and a push member configured to drive the top plug to axially slide with respect to the barrel. At least one limit piece is fixedly provided on an inner wall of the barrel to hold the clamping member.

Abstract: A detachable and retractable pen includes a holder, a barrel, a cap and a push component. The holder is in threaded connection with a front end of the barrel. The cap is in snap-fit with a rear end of the barrel. A refill is placed inside the barrel and the holder. The push component is configured to drive the axial sliding of the refill in the barrel, so that the pen refill can slide axially by means of the lateral movement of the push component, achieving the exposing and hiding of the pen tip.
