cr2032 3v lithium battery

　　A new type of cr2032 3v lithium batterydeveloped abroad is 2 to 3 times more efficient than lithium-ion batteries

　　According to reports, a research team from Florida State University and Cornell University Research found that batteries can be made from cheap and safe components and are more efficient than today's most advanced lithium-ion batteries. 2 to 3 times higher.

　　FAMU-FSU College of Engineering Postdoctoral Research Institute A. Nijamudheen, along with Cornell doctoral student Snehashis Choudhury, and other faculty at both universities, launched an investigation into what are the shortcomings of current cr2032 3v lithium batterydesigns and how they could be improved. "It's not surprising to see cr2032 3v lithium batterycosts rising over time," Choudhury said. "Wide adoption of cr2032 3v lithium batterytechnology requires cost reductions."

　　To reduce costs, the researchers addressed several specific issues related to the electrolyte, a key part of the battery's structure that facilitates the movement of ions from one electrode to another. The research team understood the chemical process by which electrolytes degrade on cr2032 3v lithium batteryelectrodes. The researchers not only discovered the mechanism of electrolyte degradation, but also discovered a variety of solutions. "We found that controlling the ionic properties of the interface (SEI) formed on the negative electrode is key," Nijamudheen said.

　　Using quantum calculations, researchers found that the source of cr2032 3v lithium batterydegradation lies in the way a component in the electrolyte called diethylene glycol polymerizes. Polymerization is a process in which molecules chemically combine to produce a long chain of molecules called a polymer. In the case of batteries, electrolytes often break apart and reform into larger molecules after being in contact with the positive and negative terminals of the cr2032 3v lithium batteryfor an extended period of time. The researchers said: "Although the degradation process itself is harmless, the substances produced by the degradation will prevent ions from entering the cr2032 3v lithium batteryelectrodes, which over time will reduce the energy that the cr2032 3v lithium batterycan store." However, although some of the polymers produced by the degradation process Materials prevent ions from reaching the electrodes, but there is evidence that other types of polymers can effectively extend cr2032 3v lithium batterylife. After performing aggregation calculations, the researchers began investigating other types of electrolytes that would not affect cr2032 3v lithium batteryperformance during the aggregation process.

　　Typically, lithium batteries are made from organic carbonate electrolytes, but these electrolytes are highly flammable, so expensive, cooling thermal regulation components are required to prevent thermal runaway and fire risk. So the researchers tested a non-flammable, stable electrolyte – lithium nitrate electrolyte.

　　Using this electrolyte, researchers began experiments on solid electrolyte SEI membranes. The SEI film is a protective layer formed due to the decomposition of the electrolyte, usually when the cr2032 3v lithium batteryis cycled for the first time.

　　The researchers used sacrificial salts or new molecules introduced through the electrolyte to naturally form a new SEI film in the battery. In addition, the researchers also introduced a chain transfer agent (a string of molecules) that interacts with diethylene glycol to form a shield. layer, protecting the negatively charged electrodes from degradation.
