O2/o2- reduction potential
Weband standard reduction potential for the O 2 /H 2 O couple is 1.23 V (vs NHE). Therefore what exact potential (-1.23V or +1.23 V) we need for water oxidation? WebWhen lithium-oxygen batteries discharge, O2 is reduced at the cathode to form solid Li2O2. Understanding the fundamental mechanism of O2 reduction in aprotic solvents is therefore essential to realizing their technological potential. Two different models have been proposed for Li2O2 formation, invol …
