Development of Redox Mediators for High-Energy-Density and High-Efficiency Lithium-Oxygen Batteries

This thesis addresses the introduction of redox mediator into lithium-oxygen batteries to improve their electrochemical performance especially in terms of practical energy density and round-trip efficiency. In chapter 1, basic electrochemistry regarding lithium-oxygen batteries and redox mediators are introduced. In chapter 2 to 4, comprehensive researches including the discovery of a new redox mediator inspired by biological system, the investigation on kinetic property of redox mediator, and the prevention of shuttle phenomenon are introduced, followed by chapter 5 summarizing the contents. This thesis is targeted to students and researchers interested in electrochemistry and energy storage systems.

Nominated as an outstanding Ph.D. thesis by the Seoul National University, Seoul, South Korea Introduces the working mechanism and impact of redox mediators in improving the performance of lithium-oxygen battery Provides comprehensive studies in developing high-performance redox mediators
