situ cycle, stability was achieved, and after 80 cycles, capacity delivered was
105 mAhg

. After 80 cycles, a decrease was observed due to the poor interface
stability, and dendrite growth may occur.
Pal et al. (Pal and Ghosh 2017) reported the PMMA–LiClO 4 -based polymer
nanocomposite electrolyte with TiO 2 as nanofiller using solution cast technique.
XRD diffractograms depict complete dissociation of salt, and PMMA peak broadens
with the addition of nanofiller. The addition of 1 wt. % TiO 2 evidences the optimum
enhancement of the amorphous content. Further, TEM analysis evidences the
nonuniform distribution and clustering, with no effect on particle size with nanofiller
loading.
