Mesoporous NH(4)NiPO(4)·H(2)O for High-Performance Flexible All-Solid-State Asymmetric Supercapacitors

Nowadays, wearable energy storage devices have been growing rapidly, but flexible systems with both excellent cycling stability and decent flexibility are still challenging. In this work, a flexible all-solid-state NH(4)NiPO(4)·H(2)O//graphene supercapacitor with remarkable performance was successfu...

description Nowadays, wearable energy storage devices have been growing rapidly, but flexible systems with both excellent cycling stability and decent flexibility are still challenging. In this work, a flexible all-solid-state NH(4)NiPO(4)·H(2)O//graphene supercapacitor with remarkable performance was successfully assembled. When cycled at a current density of 5 mA cm(−2), the device delivered 121 mF cm(−2), and showed good cycling stability after 3,000 cycles. Moreover, the all-solid-state NH(4)NiPO(4)·H(2)O//graphene supercapacitor also exhibit high mechanical flexibility with well-maintained specific capacitance, even under bending to arbitrary angles (up to 180°) and different weights (up to 50 g).
