Abstract:
The paper considers various methods of conformal coating the three-dimensional
structure of Ni foam with polymers as electrolytes in lithium-ion batteries.
Polymethylmethacrylate (PMMA), polyacrylonitrile (PAN), polyvinylidene fluoride (PVDF),
and polyethylene oxide (PEO) were chosen as polymer electrolytes because of their good ionic
conductivity and mechanical stability. Conformal coating was performed using two methods:
drop coating, dip coating. The polymer-coated three-dimensional Ni foams were characterized by
field-emission scanning electron microscopy (FE-SEM) to determine the more conformal coating
method and testing the ionic conductivity of polymers. From this research, it could be concluded
that the dip coating method allows a more conformal coating of the three-dimensional Ni foam
structure and the polymers obtained by this method have a good value of ionic conductivity.
