1. Introduction
Lithium-ion batteries command a major presence among
all rechargeable battery systems, owing to their higher energy
density and better efficiency and battery life as compared to
alternatives.[1] Improvements in Li-ion battery technology
have been driven significantly by microelectronics that
require lighter, thinner, and higher capacity batteries, partic-
ularly for portable devices.[13] There is a particular interest
in fabricating thin, flexible batteries with widespread appli-
cations in rolled-up displays, implantable devices, and smart
cards.[4,5]
One of the major challenges in the development of
these flexible batteries is to achieve a mechanically robust,
lightweight system without compromising the electrochem-
ical characteristics. This necessitates concerted improvements
in the structural, electrochemical, and design aspects of the
battery through innovations in constituent electrode, electro-
lyte, and separator materials.[6,7]
Nanotechnology offers possible solutions in new mate-
