Abstract
Synthesis and electrochemical study of novel trifluorinated diethers, namely, α-methoxy-ω-(2,2,2-trifluoroethoxy)- alkanes, as potential candidates for new-generation electrolyte solvents for lithium-metal batteries are presented. The trifluoro diethers were tested in cell configurations implying cathodes with high nickel content and revealed Coulombic efficiencies exceeding 99.9% and specific discharge capacity retention up to 99% over 55 cycles for potentials up to 4.5 V. This study opens up new prospects in targeted design of organic ether molecules as lithium-metal batteries electrolyte components.
期刊介绍：
Mendeleev Communications is the journal of the Russian Academy of Sciences, launched jointly by the Academy of Sciences of the USSR and the Royal Society of Chemistry (United Kingdom) in 1991. Starting from 1st January 2007, Elsevier is the new publishing partner of Mendeleev Communications.
Mendeleev Communications publishes short communications in chemistry. The journal primarily features papers from the Russian Federation and the other states of the former USSR. However, it also includes papers by authors from other parts of the world. Mendeleev Communications is not a translated journal, but instead is published directly in English. The International Editorial Board is composed of eminent scientists who provide advice on refereeing policy.
