Abstract: This application provides a secondary battery, including a negative electrode plate. The negative electrode plate includes a negative current collector and a negative film layer disposed on at least one surface of the negative current collector. The negative film layer contains a nitrate. The secondary battery of this application can avoid generation of lithium dendrites during cycling. This application further provides an electrical device containing the secondary battery.

Abstract: Methods and systems are disclosed for determining a plan to optimize key performance indicators (KPIs) of an industrial process. Such a plan is determined based on generating a query for information associated with the KPIs and based on receiving user-provided object information corresponding to the KPIs. The method includes receiving, at a user interface, one or more KPIs associated with an industrial process. The method includes generating, based on the one or more KPIs, at least one query for information associated with the KPI. The method includes receiving, at the user interface, a response to the at least one query. The method includes determining, by an artificial intelligence agent, a plan for optimizing the KPI.

Abstract: A negative electrode plate includes a negative electrode current collector and a negative electrode film layer on at least one surface of the negative electrode current collector. The negative electrode film layer includes a negative electrode active material, a metal hydride, a conductive agent and a binder. The negative electrode active material includes a silicon-based negative electrode active material.

Abstract: A positive electrode material plate includes: an electrode plate substrate and a coating layer arranged on a surface of the electrode plate substrate. The electrode plate substrate includes a compound of formula I: LiNixCoyM1-x-yO2 (formula I), where 0.6?x<1, 0?y?0.2, and M is at least one of Mn, Al, Ti, Zr, Mg, W, and Mo; and the coating layer is a three-dimensional network lithium phosphate layer with a thickness of 12 nm to 13 nm, and a percentage of lithium phosphate is 20% to 30%.

Abstract: A separator and a preparation method thereof, a secondary battery, a battery module, a battery pack, and an electric apparatus.
