Type: article
Abstract: The cutting-edge development of lithium-ion batteries (LIBs) focuses on improving the security and cycle performance. The separator film plays an important role in cell performance and long-term service life, which requires both flame retardancy and mechanical strength. In this work, a one-step electrospinning technique has been adopted to prepare a novel polyvinylidene fluoride/cellulose acetate/ammonium polyphosphate membrane acting as a separator in the LIBs. The electrospinning conditions have been first optimized mainly by varying the concentration of precursor solution. The electrospun membranes have been characterized using scanning electron microscopy and infrared spectroscopy. The porosity, electrolyte uptake capability, the electrolyte wettability, thermal stability, and tensile properties have also been measured.
