Langdon, Jayse; Cui, Zehao; Manthiram, Arumugam published an article in 2021. The article was titled 《Role of Electrolyte in Overcoming the Challenges of LiNiO2 Cathode in Lithium Batteries》, and you may find the article in ACS Energy Letters.Product Details of 872-36-6 The information in the text is summarized as follows:
LiNiO2 (LNO) is a high-capacity and model cathode first discovered in the 1980s that fell out of favor due to its intrinsic instabilities. However, research activities toward LNO are once again on the rise as the push for higher-energy-d. cells marches on. We demonstrate here that with appropriate modern electrolytes, major performance improvements can be achieved with LNO with no addnl. modifications. Cells with a localized high concentration electrolyte (LHCE) deliver 92% capacity retention after 200 cycles compared with 56% capacity retention in a baseline carbonate electrolyte, maintain 94% capacity after high-voltage storage compared with 77% capacity, and display a higher onset temperature of thermal runaway of 244°C compared with 188°C. These improvements are attributed to the LHCE’s high oxidative stability and its formation of fluorine-rich interphases. Although further characterization of this new class of electrolyte is necessary, this work demonstrates that modern electrolytes can be drop-in enablers of high-capacity, long-cycle-life cells. After reading the article, we found that the author used Vinylene carbonate(cas: 872-36-6Product Details 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.Product Details of 872-36-6
