Development Of Novel Materials For Rechargeable Lithium Batteries, Xuanwen Gao
University of Wollongong Thesis Collection 1954-2016
In the field of electrical energy storage, lithium ion batteries (LIBs) are considered as one of the most promising technologies due to their particularly higher energy density and longer shelf life, as well as they do not suffer from the serious memory effect problems that afflict Ni-MH batteries. Graphite and LiCoO2 are currently the most common commercial anode and cathode materials for the LIB, but they still suffer from low theoretical capacities of 372 mAh g-1 and 170 mAh g-1, respectively. Such low discharge capacity would be unable to satisfy the growing demand for large-scale potential …

Nanostructured Anode Materials With High Capacity For Rechargable Energy Storage, Li Li
University of Wollongong Thesis Collection 1954-2016
One of the great challenges in the twenty-first century is unquestionably energy storage. In response to the needs of modern society and emerging ecological concerns, it is now essential to search for new, low-cost, and environmentally friendly energy conversion and storage systems. The performance of these devices depends intimately on the properties of their materials. Nanostructured materials have attracted great interest in recent years because of the unusual mechanical, electrical and optical properties with which such materials are endowed by their specific structures. In this work, materials with unique nanostructured morphologies were prepared, which include germanium, cobalt oxide, manganese oxide, …
Preparation And Electrochemical Properties Of Nanostructured Electrode Materials For Lithium Ion Batteries, Dan Li
University of Wollongong Thesis Collection 1954-2016
Lithium ion batteries (LIBs) have been regarded as the most successful
electrochemical power sources for a wide range of applications, including consumer
devices, portable electronics, electric vehicles, and renewable energy storage, due to
their potential for high power density and high energy density. Tremendous efforts
have been made towards even further improving their high capacity, excellent rate
capability, and cycling stability by developing novel cathode and anode materials to
meet the increasing power-supply requirements. In this thesis, a series of electrode
materials, including germanium, germanate, cobalt oxide, titanium dioxide, and
lithium iron phosphate have been synthesized, and their physical and …

The lithium-ion battery is currently the most widely used electrochemical storage system on the market, with applications ranging from portable electronics to electric vehicles, to aerospace. In order to satisfy the growing demand for higher-energy and higher-power-density batteries, dramatic improvements are required. In this doctoral work, a strategy of using facile, scalable, and low-cost methods to synthesize nanostructured electrode materials was applied. The electrode materials that were investigated are of high capacity, and they include germanium, germanium oxide, tin-antimony, molybdenum dioxide, and vanadium pentoxide. Carbon allotropes such as amorphous carbon, graphene, and carbon nanotubes were also introduced into the electrode …

Global warming caused by the excessive use of fossil fuels has become a severe problem in the modern world. Increasing energy demand worldwide and mandates to minimize greenhouse gas emissions require the production of energy in a sustainable manner and efficient usage of that energy. Lithium ion batteries (LIBs) have demonstrated themselves to be one of the most promising electrochemical energy storage approaches. During the past two decades, LIBs have become the dominant power source for a wide range of portable electrical devices. The large-scale potential lithium ion battery applications, however, such as electric vehicles (EVs), hybrid electric vehicles (HEVs), …

Due to the rapid increase in the use of portable computers, mobile phones, and electric vehicles, there is an increasing demand for larger capacity, smaller size, lighter weight and lower priced rechargeable batteries. Lithium ion battery technology offers the highest energy densities by weight of all the commercial rechargeable battery technologies, with high voltage, long cycle life, and a wide environmental operation range. Commercial lithium ion battery electrodes today contain expensive and hazardous cathode (lithium cobalt oxide) and low specific capacity anode (carbonaceous materials). It is desirable to replace these materials with potentially cheaper, less toxic materials that have high …

University of Wollongong Thesis Collection 1954-2016
Lithium ion batteries have served as power sources for portable electronic devices for the past two decades. To date, they have employed polycrystalline microsized powder electrode materials. However, many next-generation electronic devices or wireless communication devices demand thin and flexible electrodes with higher energy density than ever before. Moreover, the large-scale potential lithium ion battery applications, such as in electric vehicles, (plug-in) hybrid electric vehicles, or energy storage systems in smart grids, require batteries exhibiting high rate capability, high power, and long cycle life. Due to the advantages of nanostructured electrode materials, i.e., high surface area, more lithium active sites, …
