Accordingly, the LLZO@EmimFSI@PEO derived hybrid solid electrolyte provides an ionic conductivity of 1.0脳10-4 S cm-1 at 40oC and electrochemical stability window above 5.0 V vs. Li/Li+. Furthermore, the symmetric cell of Li/hybrid solid electrolyte/Li exhibits flat voltage profiles and ...
The highest room temperature ionic conductivity and Li+ transference number are observed for PEO + 20 wt% LiTFSI + 10 wt% EMIMFSI. These prepared gel polymer electrolytes (GPEs) are thermally and electrochemically stable enough for battery application. Two different cells with graphene oxide-doped...
Introduction of EMImFSI results in the occurrence of a SEI that hinders the plating except for the 10% EMImFSI-NaFSI based electrolyte. Electrochemical cycling of a hard carbon electrode reveals that FSI- anion, mainly coming from the added ionic liquid, can introduce new peaks in the cyclic ...
Physicochemical properties of the electrolytes prepared with NaClO4, NaPF6 and NaFSI are differently influenced by the EMImFSI additive, which contributes with ionic species to the electrolyte ionic conductivity but increases its viscosity. Extension of the sodium plating/stripping is higher for more ...
[EMIm][FSI](x)[BF4]((1-x)) and [EMIm][TFSI](x)[BF4]((1-x)), respectively. For the formulations showing solely a glass transition, considered to be prospective low-temperature electrolytes, the density, viscosity and conductivity values were determined in a wide temperature range. The ...
