point is that separator must have good compatibility and less thickness (<25 μm)
with the electrodes and possess desirable mechanical, electrochemical, and stability
(thermal–voltage) properties (Arora and Zhang 2004; Zhang 2007b). Table 8.6
summarizes the selected patents in polymer electrolytes.
8.5 Summary and Conclusions
This chapter highlighted the recent updates on the solid PNCs with nanoparticle of
different shapes and specific surface area. The development of solid polymer
electrolyte as an alternative to liquid–gel polymer electrolyte has been the focus of
researchers all over the world. From the last three decades, the nanoparticles have
gained attention for the preparation of the solid polymer electrolyte for the energy
storage systems. Among the various nanoparticles used for dispersion in the polymer
matrix, nanoclay and active–passive nanofiller have been most studied. The
nanofiller and nanoclay improved the overall properties of the polymer electrolytes.
The nanofiller enhanced the electrical properties along with mechanical properties
depending on the preparation method, dispersion, surface group interaction with
polymer chains, surface area, and dielectric constant. The Lewis acid–base
