A Honeycomb-like Ammonium-Ion Fiber Battery with High and Stable Performance for Wearable Energy Storage.

ABSTRACT: Aqueous ammonium-ion batteries have attracted intense interest lately as promising energy storage systems due to the price advantage and fast charge/discharge capability of ammonium-ion redox reactions. However, the research on the strength and energy storage characteristics of ammonium-ion fiber batteries is still limited. In this study, an ammonium-ion fiber battery with excellent mechanical strength, flexibility, high specific capacity, and long cycle-life has been developed with a robust honeycomb-like ammonium vanadate@carbon nanotube (NH₄V₄O₁₀@CNT) cathode. The fiber electrode delivers a steady specific capacity of 241.06 mAh cm^-3 at a current of 0.2 mA. Moreover, a fiber full cell consisting of an NH₄V₄O₁₀@
