This application relates to the field of electrocatalytic carbon dioxide reduction and discloses a method for preparing a nickel hollow fiber membrane, comprising the following steps: S1, preparation of casting solution; S2, spinning and film formation: the casting solution is extruded into a tap water bath at a certain speed through spinning extrusion molding, while water is injected into the hollow fiber at a constant speed with gas, causing a phase change between the extruded fiber and water, and then the extruded fiber is soaked in tap water overnight; S3, sintering: oxygen or air is first introduced into a tube furnace for oxidation, and then reduction is carried out under a hydrogen atmosphere to obtain a complete metal hollow fiber membrane. By applying pure nickel hollow fiber to the field of electrocatalytic carbon dioxide reduction, compared with other gas diffusion electrodes, nickel hollow fiber, as a self-supporting gas diffusion electrode, does not require the use of binders such as Nafion solution, and compared with precious metals such as gold, silver, and copper, which are excellent for carbon dioxide reduction, nickel is inexpensive and suitable for large-scale use.

The invention discloses an automatic random breakpoint running and breakpoint continuous playing method without industry selection, and relates to the technical field of SaaS knowledge learning in the vertical industry. A unique industry identifier is preset through the system, and a user can directly enter a breakthrough process by clicking a single entrance without selecting an industry, a level or difficulty; automatically and randomly extracting questions from a corresponding industry question bank by the system, recording the number of answered questions in the current round of the user, and ensuring that the questions in the single round of breakthrough breaking are not repeated; meanwhile, the breakpoint breakpoint breaking state of the user is recorded, and the user can directly recover the progress to continue breaking after exiting; and users are supported to enter infinitely and randomly refresh questions, so that the knowledge breakthrough with light weight, high efficiency and high experience is realized. According to the invention, the problems of tedious operation, repeated questions, incapability of continuous playing and complicated process of a traditional breakthrough-making platform are solved, and the method is suitable for a SaaS drainage and knowledge training system in the vertical industry.

The application belongs to the technical field of lithium ion batteries, and provides a multilayer ceramic electrode tab and a preparation method thereof. The method comprises the following steps: sequentially coating a binder layer and an active composition layer on the surface of a current collector, and then performing heat treatment to obtain a composite; depositing a ceramic layer on the surface of the active composition layer of the composite to obtain an intermediate; and repeating the above steps to obtain the multilayer ceramic electrode tab. The application adopts a laminated mode, and can further improve the utilization rate of the battery; the active composition layer is prepared by a dry method, and the ceramic layer is deposited by an ALD deposition mode, so that the use of a solvent is avoided, and the swelling phenomenon is reduced. The application adopts a multilayer ceramic deposition mode, improves the energy density and safety of the battery, and effectively prevents lithium dendrites from directly piercing through the multilayer ceramic layer. The multilayer ceramic electrode tab provided by the application greatly improves the safety of the battery while ensuring the performance of the battery, and is suitable for large-scale use.
