The application belongs to the technical field of lithium batteries, and relates to a preparation method of a double-coated silicon-carbon composite material, an electrode and a lithium battery.The method comprises the following steps: placing a lithium dopant and a MOF material in a first organic solvent, adding a template agent and a catalyst, reacting, filtering, freeze-drying and obtaining a gel composite; in an inert atmosphere, the gel composite is heated to a first preset temperature, carbon dioxide is introduced at a preset flow rate, the temperature is lowered, the gel composite is soaked in mixed acid, pickling is performed, vacuum drying is performed, and a porous carbon composite material is obtained; liquid silane, a phosphine derivative, a dispersing agent, the porous carbon composite material and a silane coupling agent are added to a second organic solvent, spray drying is performed, primary carbonization is performed, and a silicon-carbon precursor material is obtained; resin is dissolved in a third organic solvent, a fast ion conductor and the silicon-carbon precursor material are added, secondary carbonization is performed, the temperature is lowered to a second preset temperature, a reducing gas is introduced, and a double-coated silicon-carbon composite material is obtained; the conductivity is improved, the interface stability is improved, and the full charge swelling is reduced.

The utility model discloses a battery cell depression bar for a battery module, which relates to the technical field of battery cell depression bars and comprises a depression bar frame with a rectangular structure, a bottom plate tightly attached to the battery module is arranged at the lower end of the depression bar frame, the depression bar frame and the bottom plate are enclosed to form a wire harness accommodating chamber, and a wire inlet communicated with the wire harness accommodating chamber is arranged on the depression bar frame. A wire arranging window is further formed in the upper end of the pressing strip frame, and after the wire harness enters the wire harness containing cavity from the wire inlet, an operator arranges the wire harness through the wire arranging window; and a wire harness pressing plate is arranged on the bottom plate and can be deformed to press the wire harness. The wiring harness pressing plate is used for pressing the wiring harness, so that the arrangement of the battery core wiring harness is completed simply and quickly, the wiring harness can be stored in order without spending too much time, the efficiency is improved, the cost is reduced, the production requirement is met, and the bottom sheet and the pressing strip frame are fixedly connected through a welding process, so that a closed structure is integrally enclosed. And the overall strength of the battery cell pressing strip can be greatly improved.

This invention provides a high-satiety chicken small molecule peptide and its application in chicken meal replacement powder. First, a gastric self-expanding microsphere is prepared, with yeast β-glucan and hydroxypropyl methylcellulose as the wall material and modified chicken small molecule peptide as the core material. The microsphere absorbs water and expands in the acidic environment of the stomach, generating a feeling of fullness. In the intestinal environment, it slowly releases the modified chicken small molecule peptide, promoting absorption and regulating intestinal health. Furthermore, solid-state fermentation of mixed grain powder using Aspergillus oryzae is used to prepare the chicken meal replacement powder. The addition of the gastric self-expanding microsphere and fermented mixed grain powder further enhances satiety, meeting the market demand for healthy meal replacement foods.
