NOVEL PERSPECTIVES FOR MEMBRANE SEPARATORS FOR RECHARGEABLE LITHIUM-ION BATTERIES

Popis výsledku v původním jazyce

The main reason for using nano fibred materials for separators are their both high porosity and relative surface area. These requirements are important to improve ionic conductivity of separators and ensure sufficient electrolyte volume in battery. Theseadvantages makes electrospinning very promising method of nanofibrous separators mass production. Battery separators must not take part in any electrochemical reaction. Material selection depends on chemical composition and application of accumulator. Separators in Li-ion batteries are mostly made from polypropylene (PP), polyvinylidene fluoride (PVdF) and polyethylene (PE). In this paper are described electrospinning fabrication process and discussed results of separators properties measurements. Furthermore, electric and electrochemical properties of non-commercial nanofibrous PVdF separators produced by Nafigate Corporation stock company are compared with properties of Celgard 3401 (standard on the market).
