British researchers in the latest issue of “Nature Materials” magazine has written that they have found a simple and accurate method to monitor lithium batteries in the ongoing chemical reaction, early detection and quantification of the dendritic easily lead to fires crystal formation. The researchers said the new approach will help large-scale commercial application of lithium battery.
Currently, lithium is widely used in portable computers and mobile phones, it is also the development of next-generation electric vehicles the “engine.” However, there is a major lithium defects: in a few charge and discharge cycles, in particular, are fast charging lithium batteries, the carbon anode of lithium appears small fibers (dendrite crystal) of these dendritic crystals lead to short-circuit, cause the battery to overheat or even rapid fire explosions.
Through the use of theoretical models, optical microscopy and scanning electron microscopy to study the formation of dendritic crystals, the researchers found a way to quantify the shape of the dendritic crystals has been the number of methods and the use of magnetic resonance imaging spectroscopy observations of a 1 cm long battery the chemical reactions that occur when a new authentication method.
