At zero overpotential, the exchange current density for the two reactions is the same. No net current flows. As the overpotential is made positive or negative, either the reduction or oxidation ...

In practice, an effect known as overpotential slows the electrochemical reactions: the formation and decomposition of insoluble Li 2 O 2 are slow and its conductivity is also very low. In addition ...

The electrochemical test cells produced by the team were highly promising, demonstrating a very low overpotential (0.52 V), high cycle stability over 960 hours, and highly reversible formation ...
