Cellulose nanofiber is originally prepared from natural cellulosic resources such as wood, bamboo, agricultural residuals, and several marine animals. As a promising candidate for functional materials, cellulose nanofiber behaves numerous merits including excellent mechanical properties, well optical transmission, natural interconnected network, and abundant chemical groups on fiber surface. In this work, the present status of cellulose nanofiber for the preparation of green energy storages (Li-ion battery and supercapacitors), flexible nano-de...
