“…The conductivity is 20 ~YU. The Li-activated SnO2:F coated glass was obtained by preloading the electrode as described in Res (14) with -10 mC/cm 2 of Li +in-serted into the SnO2:F electrode under potentiostatic polarization to avoid Li plating onto the electrode. WO3 of 3000 A thickness was vacuum evaporated onto SnO2:Fcoated glass by the same method as previously described (15).…”

The preparation, the electrical and rheological properties as well as the electrochemical behavior of gel electrolytes made of LiClO4‐normalpropylene carbonate (PC) electrolyte mixed with poly(methylmethacrylate) polymer (PMMA) as a stiffener are described. The addition of PMMA in various proportions to LiClO4 (M)‐PC electrolyte considerably increases the viscosity to reach for large amounts of PMMA, a solid rubber‐like material. On the other hand the conductivities at room temperature of these gels decrease very slightly and remain very close to the conductivity of the liquid electrolyte. Moreover, the electrochemical study of these materials shows a stability domain on Pt electrode between −3.55 V and +1 V (vs.Ag/Ag+). They behave like a liquid electrolyte. Differential scanning calorimetric data establish the thermal stability of these gels between −110 and +240°C after heat‐treatment and between −90 and +160°C before heat‐treatment. These results indicate that this type of electrolyte which is transparent in thin films is very promising for the realization of solid‐state electrochromic windows.

“…In addition, much research has revealed that PMeT is a promising electrochromic material [6,7]. Applications of PMeT electrodeposited in nitrobenzene for ECDs have been proposed [8][9][10], and an all-thiophene ECD was reported by Ribeiro et al [11]. PMeT belongs to a class of conjugated polymers with non-degenerated ground state symmetry and is a high-conducting polymer.…”

“…In the case of Li-PC, both counter and reference electrodes were Li foils, and the voltage range was 2.0 to 4.7 V vs Li. The low voltage limit was chosen to avoid irreversible formation of Li 2 O and LiOH [25] as well as electro-activity in ITO [25,26]; the high voltage limit was set to avoid oxidation of PC [27,28].…”

Porous thin films of Ir oxide were prepared by reactive dc magnetron sputtering onto unheated substrates. The crystallite size was ~5 nm, and a small amount of unoxidized Ir was present. The electrochromic performance was studied by optical transmittance measurements and cyclic voltammetry applied to films in aqueous and non-aqueous electrolytes, specifically being 1M propionic acid, 1M potassium hydroxide (KOH), and 1M lithium perchlorate in propylene carbonate (Li-PC). Cyclic voltammetry measurements indicated that the films had a fractal surface structure. Good electrochromism, with mid-luminous transmittance modulation between ~55 and ~90 % in ~100-nm-thick films, was documented in all of the electrolytes.
