Several IL based electrolytes with an imidazolium cation (EMI) have been investigated trying to elucidate a possible beneficial effect of mixing FSI and TFSI anions in terms of physico-chemical properties and especially Li(+) solvation. All electrolytes were evaluated in terms of phase transitions, densities and viscosities, thermal stabilities, ionic conductivities and local structure, i.e.

- The study explores the conformal coating of a polymer electrolyte called P(MePEGMA) on titania nanotubes (TiO2nts) using electropolymerization via cyclic voltammetry.
- Characterization methods such as (1)H NMR and size-exclusion chromatography reveal the formation of short polymer chains, primarily trimers, while X-ray photoelectron spectroscopy confirms the presence of both the polymer and lithium salt (LiTFSI).
- The galvanostatic tests indicate a 33% improvement in the performance of the half cell when TiO2nts are coated with the polymer electrolyte compared to using metallic Li foil alone.
In this work, self-organized titania nanotubes are sulfidated by an annealing treatment to produce TiOxSy nanotubes. Morphological, structural and electrochemical analyses show that this 3D nanostructured electrode is a potential cathode material for Li-ion microbatteries.

The morphological analysis carried out by scanning electron microscopy and transmission electron microscopy evidenced the formation of a 3D nanostructure consisting of a copolymer-embedded TiO2nt. The thickness of the copolymer layer can be accurately controlled by monitoring the electropolymerization parameters.
