Separator Electrolyte Systems for Rechargeable Batteries : LAP Lambert Academic Publishing : 9786200091239 : 6200091234 : 16 May 2019 : Lithium ion batteries (LIBs) are energy storage device which have wide range of applications from portable electronics to large scale electrical storage application in renewable energy such as wind and solar power. LIBs have dominated the past two decades due to high energy density, no memory effect, longer shelf life, and lighter material. The separator electrolyte system (SES) is placed between the cathode and anode to insulate electronically and conduct ionically. However, lithium reserves are limited, sodium is an ideal replacement for lithium since it shares many physical and chemical properties with lithium, and is also abundant. As a result, sodium-ion batteries (SIBs) currently attract huge scientific and technological interest. Electrospinning is an efficient technique to synthesize highly porous and interconnected electroactive poly (vinylide
