Hierarchical β-Co(OH)2/CoO nanosheets: an additive-free synthesis approach for supercapattery applications
- 27 Downloads
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.
