Black Phosphorus/Carbon Nanoframes for Efficient Flexible All-Solid-State Supercapacitor.

ABSTRACT: A flexible all-solid-state supercapacitor with fast charging speed and high power density is a promising high-performance energy storage and sensor device in photovoltaic systems. Two-dimensional black phosphorus (BP) is a prospective electrode nanomaterial, but it struggles to fully exert its properties limited by its self-stacking. Herein, by embedding carbon nanoparticles into the interlayer of BP microplates, the designed BP/carbon nanoframe (BP/C NF) forms a certain nano-gap on the substrate for promoting the orderly transport of charges. The corresponding supercapacitor BP/C SC has a capacity of 372 F g^-1, which is higher than that constructed from BP microplates (32.6 F g^-1). Moreover, the BP/C SC exhibits good stability with a ca. 90% of capacitance retentions
