Presentation Abstract:

Increasing demands for flexible and portable personal electronics have stimulated
considerable efforts to develop light, flexible, inexpensive and high-power energy storage
devices. All-printed flexible and soft solid-state supercapacitors are considered as
next-generation wearable energy storage systems due to the promising features as higher power
density, short charging time, long cycling stability, safety, substrate-versatile ability, high
throughput and can be produced on a large scale, which further improves the possibility of
commercial applications of flexible supercapacitors [1].

However, the main challenge for full-printed flexible supercapacitors is the the functional
inks formulation. Herein, different inks (formulated by FeOOH/MnO 2 [2] and Ag@PPy
composite nanoparticles [3], Ag@PPy@MnO 2 composite nanomaterials, NiCo 2 O 4 nanowires,
respectively) as screen-printed electrode materials are prepared by a facile method, and
solid-state flexible supercapacitors with aesthetic design are manufactured by fully
screen-printed process on different flexible substrates, including plastic, paper and textile. Using
our functional ink, we fabricate flexible supercapacitors on large area by high-volume
screen-printing technique and demonstrate a series of features, displaying excellent flexibility,
cost-effectiveness, high energy density and superior cycling stability.
