Abstract: The effect of the addition of SiO₂ nanoparticles on the properties of a polyimide cathode was explored by CV, XPS, and galvanostatic cycling methods. The capacity and average cycling potential of the cell increased in the presence of SiO₂. By quantum chemical modeling, it was shown that SiO₂ nanoparticles served as a framework for polyimide, which retained its fixed structure upon metalation with sodium.

Keywords: polyimide cathode, sodium battery, SiO₂, discharge capacity, quantum-chemical modeling.
