"4H/fcc Ir nanostructures created through phase engineering are more favorable for the reversible formation of amorphous/low-crystalline discharge products (Figure 2), thereby lowering the overpotential and promoting the cycling stability of electrochemical redox reactions. The unusual phase 4H/fcc Ir nanostructures performed much better than common fcc Ir, and achieved outstanding charge potential and energy efficiency compared to other reported metal-based catalysts used in aprotic Li-CO2 batteries"
