Sumario:[EN] This Thesis is devoted to study various combinations of new aqueous electrolytes not only in terms of selection and synthesis of salts and solvents but also interaction mechanisms. The so-called aqueous eutectic-in-salt (AEIS), bi-solvent in zwitterionic-based protic ionic liquids (BS-in-ZPIL) and tri-solvent-in-salt (TSIS) have been exhaustively studied and efforts have been taken to demonstrate the formation and evolution of the different concentrated solvation species and electrochemically active hydrogen bond complex structures following by techniques (such as Raman and NMR spectroscopies, and MD simulations) with the aim of developing low cost and excellently functional electrolytes,. Ultimately, this essay is dedicated to present the high attractiveness of designing new and low-cost aqueous electrolytes that offered an improved performance.
