Synthetic polymer-based membrane for lithium Ion batteries

Efficient energy storage systems are increasingly needed due to advances in portable electronics and transport vehicles, lithium-ion batteries standing out among the most suitable energy storage systems for a large variety of applications. In lithium-ion batteries, the porous separator membrane plays a relevant role as it is placed between the electrodes and serves as a charge transfer medium and affects the cycle behavior. Typically, porous separators membranes are comprised of a synthetic polymeric matrix embedded in the electrolyte solution. The present chapter focus on recent advances in synthetic polymers for porous separation membranes, as well as on the techniques for membrane preparation and physicochemical characterization. The main challenges to improve synthetic polymer performance for battery separator membrane applications are also discussed.Portuguese Foundation for Science and Technology (FCT) in the framework of the Strategic Funding UID/FIS/04650/2019, UID/QUI/50006/2019, UID/QUI/0686/2016 and UID/EMS/00151/2019.

The low dimensionality open a new roads of opportunities and challenges. At the nanoscale some materials present new interesting effects that should be studied and understood. The nanostructured materials present a great potential functionalities due the large surface to volume ratio when compared with the bulk. With the miniaturization of the ME materials size, applications on medical and biomedical engineering could be then explored. Different morphologies with different connectivities between the magnetostrictive and piezoelectric materials have been produced allowing the obtainment of innovative structures. In this chapter the low dimensionality of polymer based ME composites will be presented, challenges that need to be addressed in pursuing practical applications of ME devices will be discussed and promising future for research and technology in this field evaluated.Portuguese Fundação para a Ciência e Tecnologia (FCT) for financial support under projects PTDC/EEI-SII/5582/2014 and PTDC/CTM-ENE/5387/2014 and in the framework of the Strategic Funding UID/FIS/04650/2013.
