The chapter discusses the role and application of polymers (polymers and
composites) in energy storage devices. Lithium-ion batteries and supercapacitors are
the two main energy storage intermittents. The chapter underscores the utilization of
polymers in various roles in these devices and their effect on performance, in addition
to related future aspects and expectations.
Keywords: Energy, Electrolyte, Lithium ion battery, Polymer, Supercapacitor.
