2results about How to "Play a security role" patented technology

This invention relates to the field of safety protection technology for industrial lifting slings used in factory lifting and logistics transportation. Existing industrial lifting slings are frequently cut or severed by components, posing significant safety hazards and wasting resources. This invention is simple, convenient, and low-cost to manufacture, allowing for mass production and widespread marketability. The invention involves embedding appropriately sized strong magnets into a 90-degree angle steel of a suitable length. During use, the magnets adhere to the component, protecting the lifting sling and greatly ensuring safety while reducing wear and tear. This invention can be used in manufacturing industries and truck transportation industries that consume large quantities of lifting slings.

The present disclosure provides a safe conductive coating slurry, a composite current collector and a preparation method thereof, and a battery, and belongs to the field of battery materials. The safe conductive coating slurry for the composite current collector comprises, in terms of mass fraction, 15-30 parts of a main material, the main material comprising microcrystalline glass; 10-30 parts of a binder; 10-20 parts of a solvent; 0.5-2 parts of a dispersing agent; 0.5-1 part of a wetting agent; and 0.5-1 part of a leveling agent. The coating slurry of the present disclosure comprises microcrystalline glass, which can simultaneously play the roles of a conductive coating and a safe coating by only coating one layer of coating, thereby simplifying the preparation process and the coating process; when combined with an electrode active material, the coating slurry does not cause the electrode active material to fall off; and the safe conductive coating has no cracking phenomenon. The technical problems of the prior art, such as the complexity of the slurry preparation process and the coating process when the two-layer structure of the conductive coating and the safe coating is coated on the composite current collector, the easy falling off of the electrode active material when combined with the electrode active material, and the easy cracking of the conductive coating, are avoided.
