Advanced Materials For Rechargeable Batteries, Haipeng Guo

University of Wollongong Thesis Collection 2017+

As the most successful energy storage system, lithium ion batteries (LIBs) have been utilized in many different fields, such as electric vehicles, smart phones, digital cameras, laptop computers, and so on. Even though enormous efforts have been devoted to improving the performance of these batteries, they still suffer from some intrinsic problems, including poor cycling stability, insufficient rate performance, and active materials aggregation. Therefore, it is important to develop advanced materials with outstanding performance for next-generation batteries. In particular, the anode material, as an important component of the battery, is critical for the improvement of its performance and is currently …

Synthesis Of Nanoporous Carbon Derived From Hybrid Metal Organic Frameworks For Symmetric Supercapacitor, Freddy Marpaung

University of Wollongong Thesis Collection 2017+

Metal-organic frameworks (MOFs) have received much interest due to their remarkable properties, such as high surface area, controllable porosity, high electrical conductivity, high thermal stability, and good chemical stability. In addition, the properties of a MOF could be tuned by incorporation with other compounds. More interestingly, their structure could be transformed into nanoporous carbon materials via the carbonization process. Nanoporous carbons (NPCs) are promising electrode materials for electrical energy storage (i.e., batteries and supercapacitors) due to their unique properties, such as good thermal and chemical stability, high surface area, and tunable pore structures.

Nowadays, the development of new electrode materials …
