6results about How to "Good structural support" patented technology

This utility model discloses a mica sheet mass production stacking device, relating to the field of mica sheet production technology. It includes a base assembly and a support column assembly. Support column assemblies are vertically installed on the left and right sides of the base assembly, and a combined column assembly is vertically connected to the upper end of each support column assembly. Stacking components are connected to the surface of the combined column assembly. This mica sheet mass production stacking device, by symmetrically installing support column assemblies at both ends of the base assembly, provides good structural support and auxiliary stability to the combined column assembly. Furthermore, the structure allows for easy separation of the support column assembly and the combined column assembly, facilitating flexible adjustment of the number of stacking components to meet different processing needs. This also facilitates structural assistance in the mass production of mica sheets, resulting in a structure that combines both structural flexibility and stability.

This utility model discloses a bend-resistant copper-clad laminate, including a bend-resistant copper-clad laminate. By incorporating the bend-resistant copper-clad laminate, during assembly, the top and bottom reinforcing frames are first flipped open in opposite directions via an elastic connection. Then, the copper-clad laminate body is placed on the top surface of the bottom reinforcing frame. During this process, the copper-clad laminate body is fitted onto the outside of the connecting post through the assembly hole. Subsequently, the top reinforcing frame is covered and fitted onto the edge of the top surface of the copper-clad laminate body, allowing the top reinforcing frame to be nested into the assembly hole and fitted onto the outside of the connecting post, thus completing the assembly of the bend-resistant copper-clad laminate. The top and bottom reinforcing frames provide good structural support for the copper-clad laminate body, preventing bending deformation caused by uneven stress.

This disclosure provides a silicon-carbon anode sheet, its preparation method, and a soft-pack lithium battery. The preparation method of the silicon-carbon anode sheet involves: dissolving water-soluble conductive polyaniline in an organic solvent, mixing it with CMC adhesive, and then mixing it with silicon-carbon slurry and a multifunctional organophosphonic acid crosslinking agent (mixing temperature: 15℃-25℃) to obtain an anode slurry; coating the anode slurry onto a negative current collector to obtain a silicon-carbon anode sheet semi-finished product; and sequentially subjecting the silicon-carbon anode sheet semi-finished product to pre-baking (90℃-120℃) and vacuum drying (70℃-90℃, time: 2h-5h) to obtain the silicon-carbon anode sheet. This method, by adding multifunctional organophosphonic acid crosslinking agents and water-soluble conductive polyaniline, facilitates the formation of a three-dimensional conductive suppression network with high conductivity, uniform and continuous conductivity, strong toughness and strong self-healing ability. This enhances the constraint on the negative electrode slurry, reduces the volume expansion rate to <15%, inhibits silicon-carbon cracking, and improves the self-healing ability of the three-dimensional conductive suppression network, thus broadening the application of high-capacity silicon-carbon negative electrode sheets in soft-pack lithium batteries.
