N1 - This work was performed under the project "SunStorage - Harvesting and storage of solar energy", with reference POCI-01-0145-FEDER- 016387, funded by the European Regional Development Fund (ERDF), through COMPETE 2020 - Operational Programme for Competitiveness and Internationalisation (OPCI), and by national funds (PTDC/QEQ-QFI/1971/2014), through FCT - Fundacao para a Ciencia e a Tecnologia. H. Cruz and L. C. Branco are thankful for the financial support of FCT/MCTES (Post-Doc grant SFRH/BPD/102705/2014 and IF/0041/2013/CP1161/CT00). The NMR spectrometers are part of the National NMR Facility, supported by FCT/MCTES (RECI/BBB-BQB/0230/2012).

N2 - The development of chloride free Deep Eutectic Solvents (DES) based on lithium acetate, triflate, bistriflimide, and sodium triflate combined with glycerol, ethylene glycol, and polyethylene glycol (PEG400) as suitable electrolytes was successfully applied in electrochromic devices (ECD). Reversible ECD incorporating selected DES as electrolyte and bipyridinium as electrochromic probes displayed a comparable performance to conventional systems, with slower transition times (2.5 times), improving the coloration contrast and efficiency (147.1 cm2. C-1 at 520 nm) and was stable for at least 1250 redox cycles.
