Synthesis and characterization of nanowire electrodes based on carbon fabric for flexible lithium ion batteries

Abstract

This thesis proposes application of vanadium oxide nanowires and nickel cobalt oxide nanowires grown on carbon fabrics (VONW/CF and NCNW/CF) for a carbon fabric-based flexible lithium ion battery. A hydrothermal method was conducted to synthesize both the VONW/CF and NCNW/CF to be used as a cathode and an anode of lithium ion batteries, respectively. Compared with other cathode active materials, the vanadium oxide does not include a lithium element at its initial state. Thereby, a pre-lithiation process was carried out to make NCNW/CF possess lithium ions at an initial step. In addition to this, solid-state polymer electrolyte (SPE) was synthesized to resolve safety problems induced by use of liquid electrolyte in lithium ion battries. The VONW/CF and the NCNW/CF are exploited with the SPE to construct a flexible lithium ion battery.
