Recent Development of Polyvinylidene Fluoride/Cellulose Membranes Electrolyte Separator for Lithium Ion Batteries

Abstract

Lithium ion batteries (LIB) are an important energy storage system. As one component in a LIB, the separator has an important role in the safety of LIB. Separators have porous structures that make it possible to transfer lithium ions between anode and cathode. This paper discusses the method for making separators with the main material as PVdF and cellulose. Such as casting, phase inversion, paper making, and electrospinning. So, we found two potential methods that can be developed in preparing lithium-ion battery separators, casting and electrospinning. Casting has benefits like a simple preparation step and does not require much equipment, but the weaknesses are expensive processes. The electrospinning step has advantages such as an inexpensive process, but has the disadvantage of needing much equipment.
