| Description |
The choice of electrolyte solvent is expected to play a key role in influencing the lithium-oxygen battery
performance. The electrochemical performances of three electrolytes composed of lithium bis (trifluoromethane
sulfonyl) imide (LiTFSI) salt and different solvents namely, ethylene carbonate/propylene
carbonate (EC/PC), tetra ethylene glycol dimethyl ether (TEGDME) and dimethyl sulfoxide (DMSO) are
investigated by assembling lithium oxygen cells. The electrolyte composition significantly varied the
specific capacity of the battery. The choice of electrolyte also influences the overpotential, cycle life, and
rechargeability of the battery. Electrochemical impedance spectra, cyclic voltammetry, and chronoamperometry
were utilized to determine the reversible reactions associated with the air cathode
