dc.description.abstractThe electrochemical cell has been known as a paragon of energy storage since the Plante Battery in 1859 A. D. Since the establishment of electrochemistry in the early 1800s, an influx of new devices, inventions, and gadgets occurred which utilized rechargeable and portable batteries. Due to an influx of novel battery-powered devices, the dependency for portable energy storage grew rapidly. This created a demand for improved chemistry and design of battery platforms, which can focus on an array of areas (power, charging, stability). My research focuses on the improvement to the positive electrode component, Lithium Cobalt Phosphate (LCP), of lithium ion batteries by means of biotemplated synthesis and biotethering. Initial experimentation focused on the identification of solid binding peptides (SBPs) with affinity for LCP through a method known as M13 phage display. The assessment of binding affinity for each SBP was determined using output/input studies. Selected SBPs were then purchased for use in both synthesis and biotethering. SBPs were used along with other templates to create a catalog of LCP materials. These materials were thoroughly characterized using a variety of techniques (X-ray diffraction, Elemental Mapping, Electron Microscopy, Digital Imaging Analysis, Cyclic Voltammetry, and Constant Current Charging) to determine the effects of each template on electrochemical performance. Results showed that the SBP identified through phage display creates a unique type of LCP when compared to other templates. A bifunctional peptide was created by fusing the LCP binding peptide and a peptide with known affinity for multiwalled carbon nanotubes (MW-CNTs). This bifunctional peptide was used to biotether LCP to CNTs reducing CNT aggregation during cycling and resulted in an improved conductivey. Biotemplated electrodes showed improved performance in aqueous systems and improved stability in organic systems. The research presented in this dissertations provides a bio-inspired approach toward improving battery performance and enhance functional materials.
