High energy lithium–oxygen batteries – transport barriers and thermodynamics

Author affiliations

Abstract

We show that it is possible to achieve higher energy density lithium–oxygen batteries by simultaneously lowering the discharge overpotential and increasing the discharge capacity via thermodynamic variables alone. By assessing the relative effects of temperature and pressure on the cell discharge profiles, we characterize and diagnose the critical roles played by multiple dynamic processes that have hindered implementation of the lithium–oxygen battery.
