Abstract
In this Phase I SBIR program we propose to develop a novel high voltage (5V) lithium-ion battery suitable for portable electronics equipmentand transportation applications. Lithium-ion batteries are already commercially available and typically consist of carbon anode, non-aqueous electrolyte and lithium transition metal oxide cathode such as LiCoO2, LiNiO2 or LiMnO4. These systems have an operating voltage of 4V and are used as a power source for portable electronics and electrical devices. Yet, they do not provide sufficient power densities for transportation vehicles. Covalent Associates proposes a lithium-ion battery which has a favorable energy density and higher power density than the aforementioned systems, with an operating voltage of nearly 5V. TThe cell will utilize a modified graphite anode, LiNiVO4-modified cathode and stable non-aqueous electrolyte. This program will focus on optimizing the electrode material's preparation and performance, and developing a compatible electrolyte.
