Low-Crystalline Ag1.2V3O8: A Zinc-Ion Storage Cathode With an Ultrahigh Capacity of 525 mAh g-1 Enabled by Oxygen-Vacancy-Rich Coordination Environments.
Conventional vanadium-based cathodes are limited by sluggish Zn2+ transport, poor electronic conductivity, and incomplete utilization of redox-active sites. Here, redox-active Ag serves as a regulator of local coordination chemistry in a short-range-ordered low-crystalline vanadate. Ag incorporation reconstructs the lo...
