碩士 === 國立交通大學 === 理學院應用科技學程 === 102 === The high power, high safety, and high energy density are the key to the popularization and application of lithium batteries for the next generation 3C integrated products (intelligent mobile phones, tablet computers) and high power products (electric vehicles, hybrid electric vehicles, electric scooters, intelligent robots, energy storage systems for renewable energy and grid applications). In order to meet these requirements, the whole world has been actively involved in technology development and innovation of lithium battery materials. Currently, the high capacity electrode materials of lithium batteries is the major research focuses. Cathode materials play a crucial role in performances of Li-ion batteries. The conventional cathode materials such as LiCoO2, LiNiO2, LiMn2O4, and LiFePO4 are not able to meet the demand of high energy density Li-batteries for the above-mentioned applications. New lithium-rich layered-layered composite cathode materials with high capacity and excellent cycle life have attracted the most widespread attentions. In this research, I will focus on synthesis, processing, and characterizations of the composite cathode material (x Li[Li1/3Mn2/3]O2• (1-x)LiMO2). The effect of synthesis conditions on the structure and electrochemical properties of the material will be discussed.
