The Fabrication Of Advanced Electrochemical Energy Storage Devices With The Integration Of Ordered Nanomaterial Electrodes

The development and commercialization of rechargeable Li-ion battery in the 1990s has triggered the advancement of modern portable technology. Currently, with the emergence of electric vehicles and more complex gadgets, conventional lithium ion intercalation based secondary batteries could no longer live up to the demands of the end-use consumers. In this dissertation, ordered carbonaceous nanomaterials were utilized to integrate with the next-generation conversion chemistry based secondary batteries. Lithium-oxygen and sodium-sulfur battery systems were tested and developed in attempt to deliver higher energy density over the conventional Li-ion battery. The main objective of the work is to fabricate advanced electrodes that are capable of providing higher capacity in order to facilitate power grids and electric vehicles, while by doing so; the effects caused by the emission of CO2 could be significantly mitigated. Ordered carbonaceous nanomaterials were produced by the chemical vapor deposition method. Among the wide variety of carbon materials, vertically aligned carbon nanotubes were grown on a substrate and then subsequently peeled off and used as the electrode for the lithium-oxygen battery. With the combination of 2-methyl-pyrrolidone solvent, the assembled lithium-oxygen battery could achieve specific capacity of 1200 mAh·g-1 and under safe charge/discharge cycles for 50 cycles. Carbonized metal organic framework was fabricated by mixing selected precursors. Sulfur was melt infiltrated to yield the carbon/sulfur composite. The metal organic framework structure composite cathode exhibited specific capacity of 1000 mAh·g-1 for over 250 cycles for the room temperature sodium-sulfur system. In addition, nitrogen, sulfur co-doped hierarchical porous carbon was fabricated by soft template method and combined with sulfur. The N,S-HPC/S composite showed relatively lower energy density; however, with much higher cycle stability of ~10,000 cycles at a current density of 4.6A·g-1. The next generation secondary battery showed good performance yet with limited protection for the inevitable lithium dendrite growth if coupled with metallic lithium, which is an adverse phenomenon that would eventually result in the deterioration of the battery. The shortage of the battery is caused by the dendrite penetration, which could lead to safety issues including thermal runaways and explosions. Therefore, solid polymer electrolyte was designed and prepared to mechanically suppress the growth of dendrite during charging protocol. PEGDA polymer host, plasticizers and lithium salt were used to fabricate the solid ionic conducting membrane, which could achieve an ionic conductivity of 10-3 S·cm-1, a value that is comparable to the liquid electrolyte counterpart. The solid polymer electrolyte was implemented in the conventional lithium-ion battery and the advanced lithium-sulfur battery.
