Abstract: The rechargeable lithium ion batteries (LIB) are playing increasingly important roles in powering portal commercial electronic devices. They are also the potential power sources of electric mobile vehicles. The first kind of the cathode materials, LiXCoO2, was commercialized by Sony Company in 1980s, and it is still widely used today in LIB. However, the high cost of cobalt source, its environmental unfriendliness and the safety issue of LiXCoO2 have hindered its widespread usage today. Searching for alternative cathode materials with low cost of the precursors, being environmentally benign and more stable in usage has become a hot topic in LIB research and development. In the first part of this study, lithium nickel manganese cobalt oxide (LiNi0.6Mn0.35Co0.05O2) is studied as the electrode. The materials are synthesized at high temperatures by solid state reaction method. The effect of synthesis temperature on the electrochemical performance is investigated, where characterizations by, for example, X-ray diffraction (XRD) and scanning electron microscopy (SEM), for particle size distribution, specific surface area, and charge-discharge property, are done over samples prepared at different conditions for comparison. The electrochemical tests of the rechargeable Li ion batteries using LiNi0.6Mn0.35Co0.05 cathode prepared at optimum conditions are carried out in various voltage ranges, at different discharge rates and at high temperature. In another set of experiments, the material is adopted as anode with lithium foil as the cathode, and its capacitance is tested. In the second part of this study, the iron based cathode material is investigated. Lithium iron orthosilicate with carbon coating is synthesized at 700℃ by solid state reaction, which is assisted by high energy ball milling. Characterizations are done for discharge capacities of the samples with different carbon weight ratio coatings.

This book was released on 2009 with total page 418 pages. Available in PDF, EPUB and Kindle. Book excerpt: Today, the Lithium ion (Li-ion) is the fastest growing and most promising rechargeable battery chemistry. For high current demands, there is an emphasis on the importance of very low cell resistance to allow unrestricted flow of current. The electrochemical performance of Li-ion batteries relies significantly on the properties of the cathode materials, the anode materials and the electrolytes. In this study, novel anode and cathode materials were synthesized and systematically studied for Li-ion battery application. Novel anode synthesis involved the substitution of the flat foil current collectors normally used by nano- or micro-wire arrays, as the higher surface area makes it possible to pack much more active material into an electrode. Ni or Cu wire arrays with wire thicknesses of 200 nm, 400 nm or 1 \03BCm were synthesised. Carbon nanotubes (CNTs) were chosen as the Li-insertion compound due to its high theoretical reversible lithium storage capacity. Synthesis of the Cu or Ni/CNT consolidated composite anodes were done using novel synthetic techniques, combining template synthesis via electrochemical deposition and chemical vapour deposition (CVD) techniques. XRD analysis of both the Ni and Cu wire arrays after carbon nanotube deposition, confirmed that the crystallinity of the wire arrays were not altered by the CVD of carbon nanotubes. The optimal results were obtained for the 200 nm Cu/CNT consolidated composite anode. The current density obtained for the Li de-intercalation (\03AFp) was 0.463 A/g. A reversible discharge capacity of 358 mAh/g was obtained in the subsequent charge/discharge cycling. The composite anode materials showed good charge/discharge cycling performances and a high capacity integrity was maintained in the cycling behaviour analyses.

This book was released on 2015 with total page 139 pages. Available in PDF, EPUB and Kindle. Book excerpt: Developing new cathode materials is key to improving the energy density of rechargeable batteries and enabling new applications of energy storage. In this thesis, two families of materials were explored as candidate cathode materials: the dirutile and rutile polymorphs of LiMnF4, and layered lithium-excess . . . Dirutile LiMnF4 was identified from high-throughput computation as a promising conversion cathode. The dirutile polymorph was synthesized through a new low temperature route, and the rutile polymorph was discovered upon mechanical milling. With simple synthesis and electrode preparation methods, both dirutile and rutile polymorphs of LiMnF4 showed electrochemical activity. Electron diffraction confirmed both polymorphs to convert upon lithiation along different reaction paths. As with other fluorides, specific capacity was strongly linked with processing conditions. The layered lithium-excess . . . compounds were designed from recent understanding of diffusion channels in lithium-excess materials. Increasing lithium content was found to improve both discharge capacity and capacity retention. Structural studies revealed a complex nanostructure pattern of Li-Sb and Ni-Sb ordering where the interface between these domains formed the correct local configuration for good lithium mobility. The

This book was released on 2011 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The Lithium-ion (Li-ion) battery is one of the major topics currently studied as a potential way to help in reducing greenhouse gas emissions. Major car manufacturers are interested in adapting the Li-ion battery in the power trains of Plug-in Hybrid Electric Vehicles (PHEV) to improve fuel efficiency. Materials currently used for Li-ion batteries are LiCoO2 (LCO) and graphite--the first materials successfully integrated by Sony into Li-ion batteries. However, due to the high cost and polluting effect of cobalt (Co), and the low volumetric capacity of graphite, new materials are being sought out. LiFePO4 (LFP) and SnO2 are both good alternatives for the cathode and anode materials in Li-ion batteries. But, to create high-performance batteries, nano-sized carbon-coated particles of LFP and SnO2 are required. The present work attempts to develop a new synthesis method for these materials: organic template-assisted synthesis for three-dimensionally ordered macroporous (3DOM) LFP and porous SnO2. With the newly developed synthesis, highly pure materials were successfully synthesized and tested in Li-ion batteries. The obtained capacity for LFP was 158m Ah/g, which is equivalent to 93% of the theoretical capacity. The obtained capacity for SnO2 was 700 mAh/g, which is equivalent to 90% of the theoretical capacity. Moreover, Hybrid Pulse Power Characterization (HPPC) was used to test LFP and LCO for comparison and feasibility in PHEVs. HPPC is generally used to test the feasibility and capacity fade for PHEVs. It simulates battery use in various driving conditions of PHEVs to study pulse energy consumption and regeneration. In this case, HPPC was conducted on a half-cell battery for the first time to study the phenomena on a single active material, LFP or LCO. Based on the HPPC results, LFP proved to be more practical for use in PHEVs.
