Fig. 6.11 Cyclic voltammetry curves of 1-methyl-3-ethylimidazolium bis (trifluoromethyl)
(EMITFSI) solutions containing different salts, with a concentration of 0.025 M and a sweep speed
of 100 mV s −1 [67]
clearly detect the oxygen-reduced intermediates in the organic electrolyte containing
Li
+ , and then form the bond with the surface of the metal catalyst (Fig. 6.12).
It can be seen that the oxygen reduction reaction process of secondary lithium-air
batteries is very complicated: (1) the electrochemical process of the battery contains
more than one elementary reaction; (2) the electrolyte, electrode materials, and
oxygen partial pressure all affect the reaction process (3) the discharge product is
a solid substance that is insoluble in the electrolyte, increasing the complexity of

reaction on the surface of the gold electrode [68]
