Abstract: This application discloses a battery cell, a battery, and an electric apparatus. The battery cell includes an electrode assembly. The electrode assembly includes a positive electrode plate, a negative electrode plate, a separator, an insulation layer, and an adhesive layer. The positive electrode plate, the separator, and the negative electrode plate are stacked and wound, and the electrode assembly has bent regions. At least a portion of the insulation layer and at least a portion of the adhesive layer are disposed in the bent region, and the insulation layer is adhered to the positive electrode plate or the negative electrode plate through the adhesive layer. In a thickness direction of the insulation layer, a projected area of the adhesive layer is smaller than a projected area of the insulation layer.

Abstract: A battery cell includes an electrode assembly, an end cover assembly, and a shielding assembly. The end cover assembly includes an end cover. The end cover has a liquid injection hole. The shielding assembly is disposed at a side of the end cover facing towards the electrode assembly and configured to cover the liquid injection hole.

Abstract: This application discloses a battery cell, a battery, and an electric apparatus. The battery cell includes at least one electrode assembly. The electrode assembly includes a positive electrode plate, a negative electrode plate, a separator, and a porous insulation layer. The positive electrode plate, the separator, and the negative electrode plate are stacked and wound. At least a portion of the porous insulation layer is disposed in a bent region of the electrode assembly, and the porous insulation layer is disposed between the positive electrode plate and the separator or disposed between the negative electrode plate and the separator. Based on the above structure, the service life of the battery cell can correspondingly be prolonged, and the safety of the battery cell can correspondingly be improved.

Abstract: A plurality of pieces of to-be-processed data are obtained, and a plurality of groups corresponding to the plurality of pieces of to-be-processed data are further obtained. Watermarks are added to to-be-processed data in the target group by using the target group as a granularity. Because watermarks are added to the plurality of pieces of to-be-processed data by using the group as the granularity, although the to-be-processed data in the group is modified due to watermark adding, the to-be-processed data changes within a range of a small amount of to-be-processed data included in the target group, and does not change within a range of the to-be-processed data, thereby alleviating a problem that the data is severely distorted after watermark adding. When to-be-processed data with similar semantics is placed in a same group, semantics of the to-be-processed data in the target group has a relatively small change after watermark adding.

Abstract: A data masking method includes: displaying one or more groups of relational data, where the relational data includes a data subject, privacy data, and a relationship that the data subject and the privacy data meet; obtaining selection of a user for target relational data in the one or more groups of relational data; and performing masking processing on the target relational data in a data source.

Abstract: A method for producing a porous nanocrystalline semiconductor layer (100) is provided, including: a) providing a substrate (10) having a substrate surface; b) coating a semiconductor layer (12) on the substrate surface; c) coating a metal containing layer (14) on the semiconductor layer; d) heat treating the semiconductor layer and the metal containing layer at a temperature and for a time period such that the semiconductor and the metal partially interdiffuse and the semiconductor is at least partially crystallized; and e) least partially removing the metal. Further, a porous nanocrystalline semiconductor layer, a use thereof, an anode, and a secondary lithium-ion battery are provided.
