Utilizing the synergistic effect between the Schottky barrier and field redistribution to achieve high-density, low-consumption, cellulose-based flexible dielectric films for next-generation green energy storage capacitors

Due to the synergistic effect of field redistribution and the Fermi level's moving, an ESD of 31.07 J cm −3 with η of 80.03% was obtained in the SZS, which is the best performance in cellulose-based dielectric capacitors to the authors' knowledge.
