Abstract

We studied here the influence of Li+ ions on the benzene rings of nematic mixture E7, which is electrochemically adsorbed onto gold electrode surface, to highlight the ability of this mixture for the applications in the field of the rechargeable Li+-ion batteries. Raman spectra support the changes observed in electrochemical analyses while contact angle measurements show that wetting properties of E7 layer were modified after deposition of this mixture onto gold support and the doping with Li+ ions.

Graphical abstract

Contact angle of acetonitrile drops and Raman spectrum of the film of E7 nematic mixture are two main properties which show deep modifications into the film by electro chemical deposition
