Electrospinning Equipment: High-Performance PVdF - HFP/rGO Electrolytes for Li-ion Batteries 2025-04-16
In response to the growing demand for high - performance energy storage devices, this study centers on the development and characterization of novel electrolytes. An electrospinning machine is used to prepare poly(vinylidene fluoride - co - hexafluoropropylene) (PVdF - HFP) fibrous membranes loaded with various concentrations of reduced graphene oxide (rGO). Lithium ions are incorporated to form electrolytes used in coin cell batteries. Fourier transform infrared spectroscopy, Raman spectroscopy, thermogravimetric analysis, differential scanning calorimetry, and scanning electron microscopy are employed for characterization. The membranes have high porosity and electrolyte uptake. The prepared cells exhibit ionic conductivity of about 10−3 S cm−1, excellent cyclic stability with high discharge capacity, a coulombic efficiency of 95%, and a good lithium transference number. Overall, PVdF - HFP/rGO electrolytes show great potential for high - performance energy storage applications.
