Metallic Vanadium Activated by an Dissolution-deposition Process for a Superior Aqueous Zinc Ion Battery Cathode

Metallic vanadium is innovatively introduced for a superior aqueous zinc-ion battery cathode material, which is activated through dissolution-deposition transition to amorphous VO·3HO and delivers an excellent capacity of 610 mA h g at 0.1 A g and remarkable capacity retention rate of 80.3% after 1000 cycles at 1 A g.
