Abstract: Provided are an electrode assembly, a battery cell, a battery, and an electrical device. The electrode assembly includes first electrode plates and a second electrode plate that are of opposite polarities. The second electrode plate and two first electrode plates are stacked and wound to form the electrode assembly. The second electrode plate is located between the two first electrode plates. Each of the first electrode plates includes a first composite current collector and a first active material layer. The first active material layer is disposed on a surface that is of the first composite current collector and that is oriented back from the second electrode plate. The first composite current collector is configured to dielectrically isolate the first active material layer from the second electrode plate and allow passage of ions transmitted between the first active material layer and the second electrode plate.

Abstract: An electrode plate, an electrode assembly, and a secondary battery are provided. The electrode plate includes a current collector, an active material layer arranged on one surface of the current collector, and an electrical connection member electrically connected to the current collector. The active material layer is arranged on a main body portion of the current collector, the electrical connection member and the current collector are connected to each other by welding at an edge of the current collector, the welding connection region is referred to as a transfer welding region, and the current collector includes a support layer and an electrically conductive layer arranged on one surface of the support layer. The electrode plate further includes a first insulation layer arranged on a further surface of the current collector and covering at least the entirety of the transfer welding region when viewed in a thickness direction of the electrode plate.

Abstract: As feature sizes of semiconductor chips shrink there is a need for tighter overlay between layers in a lithography process. This means more advanced and larger overlay corrections may be necessary to ensure that die are properly manufactured into chips, especially in reconstituted substrates where the die can shift in the process of creating the substrate. Systems and methods for correcting these overlay errors in a lithographic process are provided. Additional rotation (theta) and projected image size (mag) corrections can be made to correct overlay errors present in reconstituted substrates by adjusting the stage and the reticle. Furthermore, these adjustments can be made allowing site-by-site or zone-by-zone corrections instead of a one-time adjustment of the reticle chuck as has been done in the past. These corrections can alleviate some of the issues associated with fan-out wafer-level packaging (FOWLP) and fan-out panel-level packaging (FOPLP).

The method comprises: acquiring first data of the master device and the slave device, respectively, each first data comprising a data file of a checkpoint and a log file; recovering data according to received first data of the master device and the slave device respectively to acquire second data of the master device and the slave device, each second data being data recovered according to data file of the checkpoint and the log file; generating third data of the master device and the slave device according to the second data of the master device and the slave device, each third data comprising second data and primary keys and characteristic values of second data; comparing third data of the master device with third data of the slave device; and outputting verification results.

Abstract: The present invention relates to a method and an apparatus for 3-D display based on random constructive interference. It produces a number of discrete secondary light sources by using an amplitude-phase-modulator-array, which helps to create 3-D images by means of constructive interference. Next it employs a random-secondary-light-source-generator-array to shift the position of each secondary light source to a random place, eliminating multiple images due to high order diffraction. It could be constructed with low resolution liquid crystal screens to realize large size real-time color 3-D display, which could widely be applied to 3-D computer or TV screens, 3-D human-machine interaction, machine vision, and so on.
