Lead Doped Carbon Nanofibers in Li-ion Batteries

摘要

Lead acid batteries have been a very reliable rechargeable battery since its inception in the mid-1800s. Lithium-Ion batteries have been sought out for their light-weight and capacity of holding large amounts of energy in a small amount of space. Few studies have been conducted in the use of lead in lithium-ion batteries.;In this thesis, lead-doped carbon nanofibers were produced by using the ForcespinningRTM method and used as an anode on a lithium-ion battery. The morphology, material characterization and thermal properties of the anode material were analyzed using the Scanning Electron Microscopy (SEM), Energy Dispersive X-Ray Spectroscopy (EDS), Thermogravimetric Analysis (TGA) and X-Ray Photoelectron Spectroscopy (XPS). Electrochemical studies on the batteries cells were cycle performance, cyclic voltammetry and rate performance.
