Fluorinated ether based electrolyte for high-energy lithium-sulfur batteries

To address the challenges associated with applying high-voltage cathodes in lithium metal batteries (LMBs) there is a need for new electrolytes enabling stable interphases at both electrodes. Here we attack this by using a dioxolane-derived cyclic fluorinated ether, 2,2-bis(trifluoromethyl)-1,3-diox ...

Today, Li-ion batteries are the ultimate rechargeable energy storage systems; however, after decades of improvements, the technology might reach its energy-density limits. Ca batteries represent a promising electrochemical systems alternative to Li-ion one. The abundance of Ca, its low redox potenti ...

The lithium transport number (t$_{Li^+}$) determination of fluorinated ether (1,2-(1,1,2,2-tetrafluoroethoxy) ethane, TFEE)-based localized highly concentrated electrolytes (LHCEs) with 1,2-dioxolane (DOL) and dimethoxyethane (DME) as solvents has been explored using molecular dynamics simulations, ...
