This thesis focuses on the synthesis, characterization and electrochemical evaluation of various nano-sized materials for use in high power and high energy lithium-ion batteries. The materials were synthesised via a continuous hydrothermal flow synthesis (CHFS) process, which is a single step synthesis method with many advantages including screening processes (chapter 5). Electrochemical energy storage is introduced in chapter 1, with a focus on high power and high energy negative electrode materials for lithium-ion batteries (and capacitors). Many different classes of materials are discussed

Lithium ion batteries (LIB) are one of the most commercially significant secondary batteries, but in order to continue improving the devices that rely on this form of energy storage, it is necessary to optimize their components. One common problem with anode materials that hinders their performance is volumetric expansion during cycling. One of the methods studied to resolve this issue is the confinement of metal oxides with the interest of improving the longevity of their performance with cycling.

Layered lithium transition-metal oxides (LMOs) are used as the positive electrode material in rechargeable lithium-ion batteries. Because transition metals undergo redox reactions when lithium ions intercalate in and disintercalate from the lattice, the selection and composition of transition metals largely influence the electrochemical performance of LMOs.

Streszczenie:

The physics of transition metal oxides is controlled by the combination and competition of several degrees of freedom, in particular the charge, the spin and the orbital state of the electrons. One important parameter responsible for the physical properties is the density of charge carriers which determines the oxidization state of the transition metal ions. The central objective in this work is the study of transition metal oxides in which the charge carrier density is adjusted and controlled via lithium intercalation/deintercalation using electrochemical methods. Lithium exchange can be achi

Ce travail théorique vise à étudier, via les méthodes Premiers Principes, les propriétés des complexes de métaux de transitions, left[Mleft(dmbpyright)_{3}right]^{n+}nCi^{-} pour un usage en batterie. Pour cette étude ab-initio, les composés mono et bi-nucléaires ont été retenus. La pertinance de notre modélisation a été validée sur les composés mononucléaires. Nous nous sommes interessé au complexes de Fe, Ru et Cu pour lesquels une validation expérimentale était possible. Notre étude a principalement consisté à faire varier les degrés de liberté que nous possédons pour optimiser le voltage e

Die untersuchten Ausgangsmaterialien α-Fe2U3, ɣ-Fe2O3, Fe3O4, CoO, Co3O4, NiO sowie CuO eignen sich durch ihre hohe theoretische spezifische Kapazität als Elektrodenmaterial für Lithium-Ionen-Batterien. Die zugrundeliegenden Mechanismen zur Speicherung der Li-Ionen konnten mit allen Phasenumwandlungen und der Bildung von Zwischenprodukten im ersten Reduktionsschritt beschrieben werden. In Abhängigkeit von der Kristallstruktur der Ausgangsmaterialien und den Reaktionsgeschwindigkeiten konnten der Gesamtreaktion die einzelnen Mechanismen Interkalation von Li-Ionen, Substitution von Kationen in d

Several stringent laws and regulations have been enforced by various National/International agencies for the adoption of sustainable methods for energy production and usage. In recent times, electric grids based on alternative renewable sources such as solar, tidal, geothermal, and biomass have witnessed an upsurge. However, the intermittent nature of renewable resources and the sub-optimal electricity distribution/transmission calls for corrective measures leading to enhancement in the efficiency of electricity utilization. It is now widely recognized that energy storage via rechargeable batt
