The three-dimensional (3D) structure of batteries nowadays obtains a lot of attention
because it provides the electrodes a vast surface area to accommodate and employ more active
material, resulting in a notable increase in areal capacity. However, the integration of polymer
electrolytes to complicated three-dimensional structures without defects is appealing. This paper
presents the creation of a flawless conformal coating for a distinctive 3D-structured NiO/Ni anode
using a simple thermal oxidation technique and a polymer electrolyte consisting of three layers of
PAN-(PAN-PVA)-PVA with the addition of Al2O3 nanoparticles as nanofillers. Such a composition
with a unique combination of polymers demonstrated superior electrode performance. PAN in the
polymer matrix provides mechanical stability and corrosion resistance, while PVA contributes to
excellent ionic conductivity. As a result, NiO/Ni@PAN-(PAN-PVA)-PVA with 0.5 wt% Al2O3 NPs
configuration demonstrated enhanced cycling stability and superior electrochemical performance,
reaching 546 mAh g1 at a 0.1 C rate.
