American scientists develop cell phone batteries that will not detonate

Smartphones have come a long way since their inception, offering powerful performance and advanced features in the age of smart technology. However, while the devices themselves have evolved rapidly, battery technology has struggled to keep up. One of the most persistent issues remains battery life, but more importantly, there's an ongoing concern about safety. Although the number of reported incidents involving exploding phone batteries is relatively low, each one sparks widespread fear and concern among users. In response to these challenges, researchers at the University of North Carolina at Chapel Hill are exploring new materials that could make batteries safer and more reliable. Their recent breakthrough involves a material known as perfluoropolyether (PFPE), which is commonly used in industrial applications like mechanical lubrication and marine anti-fouling. Surprisingly, PFPE shares a similar chemical structure with traditional lithium battery electrolytes. Inspired by this discovery, the research team decided to test PFPE as a replacement for conventional electrolytes. The results were promising—batteries using PFPE showed exceptional stability, with nearly zero risk of combustion or explosion. Importantly, they maintained normal internal chemical reactions, ensuring that the battery functioned as expected. Looking ahead, the researchers plan to refine their approach further, aiming to improve the efficiency of energy storage and release within the battery. They also believe that PFPE’s excellent low-temperature resistance makes it ideal for use in extreme environments, such as deep-sea exploration or aviation equipment. This innovation could mark a major step forward in making our everyday devices safer, more efficient, and more versatile than ever before.

6x36 Stainless Steel Wire Rope

The phosphating-Coated Steel Wire Rope produced by the patented technology is preferably manganese-based or zinc-manganese-based phosphating. Compared with the production process of the smooth steel wire rope, only the final wear-resistant phosphating treatment process is added. The corrosion resistance is greatly improved, and the phosphating steel wire is used to directly twist the steel wire rope. The current fatigue test data show that the fatigue life of the phosphating-coated steel wire rope is about 3-4 times that of the smooth wire rope with the same structure (under comparable conditions in the laboratory). sex.
