abstract = {The construction of flexible electrochemical devices for
energy storage and generation is of utmost importance in
modern society. In this article, we report on the synthesis
of flexible MoS2-based composite paper by high-energy shear
force milling and simple vacuum filtration. This composite
material combines high flexibility, mechanical strength and
good chemical stability. Chronopotentiometric
charge–discharge measurements were used to determine the
capacitance of our paper material. The highest capacitance
achieved was 33 mF·cm−2 at a current density of 1
mA·cm−2, demonstrating potential application in
supercapacitors. We further used the material as a cathode
for the hydrogen evolution reaction (HER) with an onset
potential of approximately −0.2 V vs RHE. The onset
potential was even lower (approximately −0.1 V vs RHE)
after treatment with n-butyllithium, suggesting the
introduction of new active sites. Finally, a potential use
in lithium ion batteries (LIB) was examined. Our material
can be used directly without any binder, additive carbon or
copper current collector and delivers specific capacity of
740 mA·h·g−1 at a current density of 0.1 A·g−1. After
40 cycles at this current density the material still reached
a capacity retention of $91\%.$ Our findings show that this
composite material could find application in electrochemical
energy storage and generation devices where high flexibility
and mechanical strength are desired.Keywords: flexible
