According to the physics website reported that electronic equipment becomes smaller, more powerful, you need faster, smaller, more stable battery, at present, the United States University of Illinois chemist recently developed a solid super-ion conductor, will become a new generation of lithium Battery design basis.
In a recent study published in the journal Nature News, Prashant Jain, a professor of chemistry at the University of Illinois, and SarahWhite and PrognaBanerjee, This material - miniature copper selenide nanoclusters.
"We have witnessed the rapid development of nanoelectronic devices, we need microcells to be placed on the chip, but the use of liquid electrolytes is not achievable. We use nanostructured materials to achieve the core features of lithium-ion battery technology, they have a large number of Heat and mechanical stability, there is no leakage problem, we can make a very thin layer of electrolyte, so we can make the battery miniaturization.
Standard lithium ions and other ion batteries are filled with liquid electrolytes where lithium ions can move through, and when the battery is used, the ions flow in one direction and flow in the opposite direction when the battery is charged. However, there are some shortcomings in the liquid electrolyte: with the battery cycle of the degradation process, the battery needs a larger volume, and easy to leak and a high degree of flammability. This will cause mobile phones, laptops and other electronic devices to explode, but the solid electrolyte is more stable, where the ions move more slowly, greatly reducing the effectiveness of battery applications.
Copper selenide nanoclusters combine the advantages of liquids and solid electrolytes: solid stability, ions can move freely as in liquid electrolytes. Copper selenide is considered to be a superheavy conductor in a high temperature state, but this miniature nanoclusters have been confirmed for the first time that the substance is a super-ion conductor at room temperature.
