Randomized trial demonstrates excellent cycling stability in zinc-ion batteries, suggesting improved commercialization potential.

To develop a cathode material for aqueous zinc-ion batteries that combines good rate performance and long cycle life.
Developed Zn0.52V2O5−a·1.8H2O cathode via in situ phase transformation from Zn3V3O8.
Evaluated structural stability during phase transformation and zinc mobility.
Conducted theoretical calculations and experimental evidence to assess properties.
ZVOH achieved a reversible capacity of 286.2 mAh g−1 at 0.2 A g−1 and 161.5 mAh g−1 at 20 A g−1.
Maintained a cycling retention of 95.4% over 18,000 cycles.
Structural self-optimization showed positive effects on Zn2+ mobility.

Liang et al. (2022) studied this question.
