Although these aspects are typically discussed separately, they are deeply interconnected: indeed, a new electrolyte can allow the use of different cathodes with higher energy, lower cost or more pronounced environmental compatibility. In this respect, we focus on an alternative class of electrolyte ...
The promising rate performance and capacity retention demonstrate the importance of proper electrolyte engineering for the K/bilayered￢2O5 batteries, and the good compatibility of highly concentrated glyme‐based electrolytes with positive electrode materials for PIBs.doi:10.1002/batt.202000003...

In this work, the effect of electrolyte composition was evaluated on lithium-oxygen (Li-O-2) battery using carbon cloth air electrode. Seven ether-based solvents were measured for their conductivity, viscosity, contact angle and decomposition temperature. The results were compiled with other physical...
This study demonstrates that the amount of discharge product (Li2O2) precipitated on the separator in a lithium oxygen cell using glyme-based electrolytes depends on the anion. The stability of the discharge intermediate (LiO2) in the electrolyte has been shown to depend on the anionic species,...
The importance of the electrode/electrolyte interface, especially the solid electrolyte interphase (SEI), for achieving reversibility of Li metal anodes has been extensively studied. Herein, we focused on the impact of the Li ion transport properties in oligoether (glyme)‐based electrolytes...
Analysis of Ion Transport in Glyme-based Electrolyte Solutions for Li-air BatteriesTo clarify the relationship between ion transport behavior and Li deposition/dissolution reaction at Li metal negative electrode (NE) for Li-air batteries, 1.0 M of LiSO_3CF_3/tetraglyme(G4) and LiN(SO_2CF_3...
The formation of a stable solid electrolyte interphase (SEI) is a prerogative for functional lithium metal batteries. Herein, the formation and evolution of such SEI in contact with glyme-based electrolytes is investigated under open circuit voltage and several constant current cycles. An important ...
We describe here sodium trifluoromethanesulfonate (NaCF3SO3) electrolyte system based on tetraethylene glycol dimethyl ether (tetraglyme). The ionic conductivity of the electrolytes showed a maximum value of 1.6?mS?cm?1 for 40?mol% of NaCF3SO3 at room temperature and increased up to of 9.5...
