In 2022,Wu, Li-Na; Wang, Zheng-Rong; Dai, Peng; Xie, Yu-Xiang; Hou, Cheng; Zheng, Wei-Chen; Han, Fa-Ming; Huang, Ling; Chen, Wei; Sun, Shi-Gang published an article in Chemical Science. The title of the article was 《A novel high-energy-density lithium-free anode dual-ion battery and in situ revealing the interface structure evolution》.Recommanded Product: 872-36-6 The author mentioned the following in the article:
Lithium-free anode dual-ion batteries have attracted extensive studies due to their simple configuration, reduced cost, high safety and enhanced energy d. For the first time, a novel Li-free DIB based on a carbon paper anode (Li-free CGDIB) is reported in this paper. Carbon paper anodes usually have limited application in DIBs due to their poor electrochem. performance. Herein, by using a lithium bis(fluorosulfonyl)imide (LiFSI)-containing electrolyte, the battery shows outstanding electrochem. performance with a capacity retention of 96% after 300 cycles at 2C with a stable 98% coulombic efficiency and 89% capacity retention after 500 cycles at 5C with a stable coulombic efficiency of 98.5%. Moreover, the electrochem. properties of the CGDIB were investigated with a variety of in situ characterization techniques, such as in situ EIS, XRD and online differential electrochem. mass spectrometry (OEMS). The multifunctional effect of the LiFSI additive on the electrochem. properties of the Li-free CGDIB was also systematically analyzed, including generating a LiF-rich interfacial film, prohibiting Li dendrite growth effectively and forming a defective structure of graphite layers. This design strategy and fundamental anal. show great potential and lay a theor. foundation for facilitating the further development of DIBs with high energy d. After reading the article, we found that the author used Vinylene carbonate(cas: 872-36-6Recommanded Product: 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.Recommanded Product: 872-36-6
