摘要: Abstract Diluents composed of H 2 O and dimethyl sulfoxide (DMSO) were added to 1-ethyl-3-methylimmidazolium dicyanamide (EMI-DCA), yielding an electrolyte system that is potentially applicable for Zn–air batteries. critical enhancing both the conductivity Zn/Zn(II) redox kinetics, but impairs reversibility cyclability. DMSO has ability stabilize from decomposition beneficial maintaining Improved kinetics reversibility, together with good cyclability up 200 cycles, was achieved in EMI-DCA + H O + DMSO a mole ratio 1:1.1:2.3.
