Application of 872-36-6 And the article was included in Journal of the Electrochemical Society in 2020. The article conveys some information:
With the urgent demand for higher energy d. storage system, much attention has been focused on the Li metal based batteries. During the exploration of new strategy for the Li metal protection, numerous researches are based on Li/Li symmetry cell for galvanostatic cycling tests. Here, the relationship between some exptl. parameters (size of Li foil, thickness of separator and electrolyte amount) and Li/Li symmetry cell cycling performance are systematically explored. It was found that the cycling stability of Li/Li symmetry cell has been significantly improved when the size of Li foil decreases or the thickness of separator increases. In the designed experiments, it can be seen that the failure of most of cells is attributed to the decrease in ions transport ability due to continuous consumption of the electrolyte and continuous increase of dead Li. At last, the investigation of electrolyte amounts reveals that Li/Li symmetry cell exhibits lower Li deposition overpotential and longer cycling life as adding more electrolytes. Therefore, the work suggests that research on the protection of electrolyte is very important issue in promoting the commercialization of Li metal batteries. Standardizing exptl. parameters during the experiment can make more efficient comparison of different literature results achieved. The results came from multiple reactions, including the reaction of Vinylene carbonate(cas: 872-36-6Application of 872-36-6)
Vinylene carbonate(cas: 872-36-6) belongs to esters. Alkyl carbonates find applications as solvents for lithium ion battery electrolytes and the use of high quality battery grade electrolytes having extremely low water (<10 ppm) and acid (<10 ppm) contents are critical for achieving high electrochemical performance.Application of 872-36-6
