Abstract: A stacking device may include a negative delivery structure, a separator delivery structure, a first heater and a positive delivery structure. The negative delivery structure may be configured to deliver a negative electrode sheet. The separator delivery structure may be configured to deliver separators to two sides of the negative electrode sheet such that the separators are attached to the negative electrode sheet. The first heater may be arranged downstream of the separator delivery structure and configured to heat the negative electrode sheet and the separators. The positive delivery structure may be arranged downstream of the first heater and configured to deliver positive electrode sheets to the two sides of the negative electrode sheet such that the positive electrode sheets are attached to the separators.

Abstract: A method of making an integrated circuit includes steps of selecting a first cell and a second cell for an integrated circuit layout from a cell library in an electronic design automation (EDA) system, the first and second cells each having a cell active area, a cell gate electrode, at least one fin of a first set of fins, and a cell border region, each cell also having the active area at an exposed side, and placing the first exposed side against the second exposed side at a cell border. The method also includes operations of aligning at least one fin of the first set of fins with at least one fin of the second set of fins across a cell border.

Abstract: Provided are an electrode assembly, a battery cell, a battery and an electrical device, belonging to the technical field of battery manufacturing. The electrode assembly comprises: a first electrode sheet, comprising a plurality of bending segments and a plurality of stacking segments arranged in layers, wherein each bending segment is configured to connect two adjacent stacking segments, the first electrode sheet has a first broken seam, and the first broken seam extends in the width direction of the first electrode sheet to break the first electrode sheet; and a plurality of second electrode sheets, wherein the polarity of the second electrode sheet is opposite to the polarity of the first electrode sheet, and each second electrode sheet is arranged between two adjacent stacking segments in the stacking direction of the plurality of stacking segments.

Abstract: The disclosure relates to an electrode assembly and its forming method and a manufacturing system, a secondary battery, a battery module and a device. The electrode assembly includes: a first electrode plate including a plurality of bending sections and a plurality of stacked first stacking sections, each bending section being configured to connect two adjacent first stacking sections, herein the bending section includes a guiding portion for guiding the bending section to be bent during production; and a second electrode plate with a polarity opposite to that of the first electrode plate, the second electrode plate including a plurality of second stacking sections, and each second stacking section being disposed between two adjacent first stacking sections.

Abstract: A cigarette paper additive having harm reduction function and application thereof are provided. The additive contains alkali metal salts of butane tetracarboxylic acid or cyclobutane tetracarboxylic acid which are prepared by reacting the butane tetracarboxylic acid or cyclobutane tetracarboxylic acid with alkali. The application thereof is evenly adding the aqueous additive solution at different concentrations to cigarette paper by a metering rod-type film transfer sizing machine in a sizing section of the cigarette paper production, and the produced cigarette paper is used for cigarette production that can effectively reduce release of CO, phenol and tar in the mainstream smoke, and has better effects of harm reduction and tar reduction. The method of the invention is easy, does not need to alter the existing cigarette paper production process, and has low cost and higher industrial application value.
