Hydrothermal preparation of Phyllostachys pubescens – nanocellulose/graphene aerogel as a simple device for supercapacitors

Abstract

Bamboo nanocellulose can be regarded as a promising biomass material for the preparation of sustainable energy devices due to its unique structure, excellent properties, and wide range of sources. A highly conductive electrochemical energy storage was synthesized due to the excellent electrical conductivity of graphene and the high surface area of nanocellulose and graphene, which was beneficial for producing a network structure. The symmetric capacitor assembled from the Phyllostachys pubescens nanocellulose/graphene aerogel (CGA) electrode exhibited a high specific capacitance of 125.5 F/g at 5 mV/s and extreme stability of 98.3% capacitance retention ratio after 5000 cycles at 2 A/g. This nanocellulose-graphene electrode showed potential for future high-performance supercapacitors.

Cellulose nanofibrils–graphene hybrids: recent advances in fabrication, properties, and applications

“…16(IV)) have also been scrutinized to extend the applicability of functionalized GO/ CNFs for a wide range of applications such as shape memory polymers, gas barrier films, and supercapacitors. 175,176,[182][183][184] Nevertheless, further research needs to be conducted shortly to push forward the effectiveness of these hybrids through the control of the production processes and the enhancement of the demanding properties for advanced applications.…”
