Abstract
The energy density of Li-ion batteries can be enhanced by utilizing cathodes that have significantly higher energy density than that of state-of-the-art LiCoO2. The proposed program focuses on developing novel nanocomposites with a theoretical energy density of 800 Wh/kg, which is more than 60% higher than that of the practical energy density of LiCoO2. Working in collaboration with a leading developer of Li-ion batteries in Phase I, we will demonstrate that it is possible to produce stable and high energy density nanocomposite cathodes. These cathodes will lead to economical, high energy density and long cycle life rechargeable Li-ion polymer batteries at discharge rates acceptable in commercial Li-ion batteries. As part of Phase I work, the electrochemical properties of these nanocomposite cathodes will be evaluated in Li test cells with a liquid electrolyte. In Phase II, prototype batteries will be fabricated and tested for performance, along with the optimization and scaling of the powder synthesis process.
