Abstract: A lithium strip that can be used in lithium supplementation equipment is described. The lithium strip has a first surface, and a thinned area is formed at the edge of the first surface along the width direction of the lithium strip to form a space for accommodating a release agent at the thinned area. The thinned area is designed to enable the lithium strip to pick up more release agent when it is applied to a coating device, and the release agent can remain in the above thinned area. The presence of the thinned area in the lithium strip can reduce the lithium load per unit width, so that during the calendering process of the lithium strip, there will be no calendering exceeding the preset width, so that the lithium strip will not stick to the roller after calendering.

Abstract: The present disclosure provides a two-dimensional scalable superconducting qubit structure and a method for controlling a cavity mode thereof. The two-dimensional scalable superconducting qubit structure includes: a superconducting qubit chip comprising a plurality of two-dimensionally distributed and scalable qubits; a capacitor part of each of the qubits has at least five arms distributed two-dimensionally, two of the at least five arms in each qubit are respectively connected with a read coupling circuit and a control circuit, and the other at least three arms are coupled with adjacent qubits through a coupling cavity.

Abstract: Disclosed are a packaging tray structure and a substrate packaging structure. The packaging tray structure comprises a first tray including a first surface and a recess formed on the first surface for placing a to-be-packaged object; a second tray stacked on the first surface and cooperating with the first tray; a protective gasket disposed between the first tray and the second tray; and a limiting portion provided on at least one of the first tray and the second tray for limiting shift of a protective gasket. The limiting portion supports the protective gasket in such a manner that a gap is maintained between the protective gasket and the to-be-packaged object.

Abstract: A backlight module, a display panel and a display device. The backlight module includes a first light transmission substrate arranged on a light-emitting face. A projection of the first light transmission substrate on the light-emitting face coincides with the light-emitting face. A first reflection mirror and a second reflection mirror are also arranged on the first light transmission substrate. The first and second reflection mirrors are spaced apart and facing each other, and the second reflection mirror is arranged in such a way as to enable vertical emergent light on the light-emitting face to be incident to the first reflection mirror after undergoing a total reflection. The first reflection mirror is arranged in such a way as to enable light reflected by the second reflection mirror to exit after undergoing a total reflection. A plurality of light transmission holes are evenly distributed on the second reflection mirror.
