Flexible, lightweight, and green cellulose films are highly desired to meet the increasing demands of flexible electronics, but they show a trade-off between their electrical conductivity and electrochemical properties. In this context, a phosphorus self-doped, interfacially-coupled electron transfer network was constructed to improve the interfacial bonding strength between nickel sulfide (Ni3S2) and bamboo fiber film (Ni3S2/BFF) to prepare biomass-based flexible electrodes with high specific capacitance (Ni3S2/BFF). Due to interfacial coupling, the conductive network was interconnected with ...
