Étude des propriétés de liquides ioniques protiques en tant qu'électrolytes pour des supercapacités à base de dioxyde de ruthénium
This thesis on the development of room temperature protic ionic liquids as electrolytes in ruthenium-dioxide based faradaic superpacitors consists of three separate studies. The first one establishes which properties of molten salts need to be optimized for this application by using the data obtained from the analysis of a series of protic ionic liquids composed of trifluoroacetic acid and N-heterocyclic bases. The second study elaborates on the effect of colored impurities on the properties of ionic liquids and also reports practical aspects which need to be accounted for during their synthesis. The third study focuses on important structure–property relationships for a series of protic ionic liquids with pyridinium cations and various anions. Altogether, the results presented in here should allow a more efficient design of ionic liquids with desirable properties for application as electrolytes in the future.
