Zhou’s research team has effectively created a high-performing lithium-ion oxygen (Li–O 2) battery by utilizing commercially available silicon (Si) particles as the anode . A robust solid–electrolyte interface (SEI) coating was formed on the surface of the silicon (Si) anode.
Furthermore, as the battery is being discharged, the lithium anode exhibits a remarkably high specific capacity and a comparatively low electrochemical potential (versus the standard hydrogen electrode (SHE) at −3.04 V), ensuring ideal discharge capacity and high operating voltage . 2.1. Basic Principles of Lithium–Oxygen Batteries
Lithium-Air (O 2) batteries are considered one of the next-generation battery technologies, due to their very high specific energy. In parallel, Redox Flow Batteries (RFBs) are getting much attention for energy transition because of their highly flexible design that enables the decoupling of energy and power.
In this study, a redox flow lithium–oxygen battery by using soluble redox catalysts was demonstrated for large-scale energy storage. The new battery configuration enables the reversible formation and decomposition of Li 2 O 2 via redox targeting reactions in a gas diffusion tank.
The practical capacity of lithium-oxygen batteries falls short of their ultra-high theoretical value. Unfortunately, the fundamental understanding and enhanced design remain lacking, as the issue is complicated by the coupling processes between Li 2 O 2 nucleation, growth, and multi-species transport.
