Preparation and characterization of gel polymer electrolytes based on electrospun PLA/PHB membranes for lithium-ion batteries.

摘要

Biodegradable polymers have economic and environmental benefits due to cheap in cost and biodegradability, what more they are promising alternatives to traditional (petro)polymers as they fulfill current environmental concerns in terms of environmental pollution, greenhouse gas emissions and the depletion of fossil resources. However, the battery industry represents one of the important sectors of industry where the use of the biodegradable, non-toxic substitute materials has not rapidly developed. Utilizing environmental friendly polymers in polymer electrolytes and electronics field can be good replacement for some harmful existing materials and admirable category for green energy applications such as batteries, supercapacitors, solar cells, etc. [1]. The poly(lactide) (PLA) (Fig.1) has been the frontrunner in biodegradable polymers due to its attractive mechanical properties, renewability, biodegradability and relatively low cost. Different kind from PLA is a biodegradable polyhydroxybutyrate (PHB), (Fig.l), obtained from a renewable resource, showing a biodegradation rate of about 3 months after soil burial [2-30].
