Abstract:
In this article, we report a facile and environmentally friendly glutamic acid-assisted hydrothermal strategy for the preparation of ultrathin two-dimensional (2D) β-Ni(OH)2 nanosheets with a thickness of about 2 nm, which exhibit a maximum specific capacitance of 2537.4 F g(-1) at a current density of 1 A g(-1), even at 10 A g(-1), the specific capacitance is still maintained at 2290.0 F g(-1) with 77.6% retention after 3000 cycles.
