Abstract: Tremendous efforts have been devoted to the development of electrode materials, electrolytes and separators for Lead Acid energy-storage devices to address the fundamental needs of emerging technologies ranging from vehicle starter batteries, mobile industrial applications (e.g. forklifts and other automated guided vehicles) to stationary power storage (e.g. uninterruptable power supply). However, binders, as an important component of energy-storage devices, are yet to receive similar attention. Binders should have good thermal, physical and chemical stability. They should be efficient, economic and environmental friendly. Polyester has been the dominant binder in the lead acid battery industry. To understand the binding mechanism in electrode assembly of energy-storage devices (Lead Acid Batteries) state-of-the-art structural characterizations were carried out with SEM and XRD for binder research studies. The molecular vibrations studies to find the bond interactions within electroactive materials were studied with FT-IR analysis and the thermal behavior of binders was predicted with DSC. Polymeric binders will play crucial roles in future high-performance energy-storage devices.
