This paper reports the synthesis and characterization of hydrated vanadium oxide (VOH) and chemically preintercalated polyanilines in VOH as the cathode material for aqueous zinc-ion batteries. The synthesized PAVO-H has a high surface area and rod-shaped morphology. PAVO-H offers high specific capacities and a high capacity retention rate over 3000 cycles.
Thispaper reports the synthesis and characterization of hydratedvanadium oxide (VOH) and chemically preintercalated polyanilines inVOH, labeled as PAVO-H as the cathode material for aqueous zinc-ionbatteries. Synthesized PAVO-H has a high surface area and rod-shapedmorphology. PAVO-H has an increased interlayer distance of 13.36 & ANGS;.PAVO-H offers high specific capacities of 330 and 225 mAh g(-1) at 50 mA g(-1) and 4 A g(-1) ofcurrent densities, respectively, with a 92% capacity retention rateof over 3000 cycles. The preintercalation of polyaniline is likelyto catalyze the redox reaction and facilitate and simplify transportkinetics. It is also possible that the preintercalation of polyanilinepermits the insertion of large hydrated Zn ions and reduces the formationof zinc basic salts.
