Abstract:
Among the rechargeable batteries, a Li-S battery is potentially of the highest possible gravimetric capacity and theoretical energy density, ranging up to a factor of five beyond conventional Li-ion batteries. Herein, we present the electrochemical properties and performance of a novel sulfur-carbon nantube fibers composite as the cathode for rechargeable polymer lithium batteries. The microstructure of the carbon nanotube fibers and the composite was characterized by TEM, SEM, XRD, and BET surface area. The electrochemical performance of the composite cathode in a polymer electrolyte was studied by galvanostatic and cyclic voltammetry methods. We have obtained very promising results based on which we discuss the electrochemical reaction mechanism of the sulfur-carbon nanotube fibers composite in combination with the polymer electrolyte and metallic lithium as the anode. The laboratory assembly process is simple, generic and broadly applicable, conceptually providing new opportunities for tailored design that can be extended to new composite electrode materials.
