abstract = {The safe, flexible, and environment-friendly Zn-ion
batteries have aroused great interests nowadays.
Nevertheless, flagrant Zn dendrite uncontrollably grows in
liquid electrolytes due to insufficient surface protection,
which severely impedes the future applications of Zn-ion
batteries especially at high current densities. Gel
electrolytes are emerging to tackle this issue, yet the
required high modulus for inhibiting dendrite growth as well
as concurrent poor interfacial contact with roughened Zn
electrodes are not easily reconcilable to regulate the
fragile Zn/Zn2+ interface. Here we demonstrate, such a
conflict may be defeated by using a mechanoadaptive
cellulose nanofibril-based morphing gel electrolyte
(MorphGE), which synergizes bulk compliance for optimizing
interfacial contact as well as high modulus for suppressing
dendrite formation. Moreover, by anchoring desolvated Zn2+
on cellulose nanofibrils, the side reactions which induce
dendrite formation are also significantly reduced. As a
result, the MorphGE-based symmetrical Zn-ion battery
demonstrated outstanding stability for more than 100 h at
the high current density of 10 mA·cm−2 and areal capacity
of 10 mA·h·cm−2, and the corresponding Zn-ion battery
delivered a prominent specific capacity of 100 mA·h·g−1
for more than 500 cycles at 20 C. The present example of
engineering the mechanoadaptivity of gel electrolytes will
shed light on a new pathway for designing highly safe and
flexible energy storage devices.},
