Hierarchical β-Co(OH)2/CoO nanosheets: an additive-free synthesis approach for supercapattery applications
Cobalt hydroxide nanosheets have been synthesized via facile and affordable simple chemistry route without any additives for structure design. Co(OH) 2 nanosheets exhibit a maximum specific capacity of 111 C g −1 at a current density of 0.5 A g −1 . Asymmetric supercapacitor (Co(OH) 2 //AC) has been...

Summary: | Cobalt hydroxide nanosheets have been synthesized via facile and affordable simple chemistry route without any additives for structure design. Co(OH)
2
nanosheets exhibit a maximum specific capacity of 111 C g
−1
at a current density of 0.5 A g
−1
. Asymmetric supercapacitor (Co(OH)
2
//AC) has been fabricated and it delivers the specific capacitance of 34 F g
−1
with the power density of 300 W kg
−1
at a current density of 1 A g
−1
. These profitable features of cobalt hydroxide nanosheets prepared in the present work are quite promising electrode material for high-performance supercapatteries. |
