BACKGROUND
Batteries have become an important aspect of energy storage in the United States. The battery industry has become a $10 Billion a year business. Battery construction materials include zinc, manganese, lithium, and many more. One metal that has received sparse attention as a candidate for battery construction material is uranium. Based on the electrochemical literature, uranium is likely to have a significantly higher power density than lead based batteries that are commonly used as secondary power batteries. In fact, uranium may have similar electrochemical properties to lithium.
The Paducah Gaseous Diffusion Plant located in the western part of the Commonwealth of Kentucky contains cylinders with over 5 billion pounds of uranium hexafluoride (UF6). UF6 will be recycled into uranium and fluoride compounds. This will provide a large supply of depleted uranium.
GOALS
1. Characterize uranium dioxide’s electrochemical properties in various organic solvents/lithium salts commonly used in commercial battery industry. These experiments will be performed in a glove box where the moisture and oxygen concentration will be controlled. These tests will mainly consist of cyclic voltammetry and impedance spectroscopy experiments. This information will be used to construct a battery with uranium dioxide as the cathode.
2. Manufacturing of uranium-lithium compounds in a muffle furnace to mirror the construction of manganese-lithium compounds commonly used in commercial batteries. Once these compounds are manufactured, their electrochemical behavior in common organic solvent/lithium salts will also be characterized. This information will also be used to construct a battery consisting of lithium-uranium dioxide.
OBJECTIVES
The objectives are to electrochemical data suitable for properly designing two batteries:
Two years
1. A Report characterizing uranium dioxide in organic solvents/lithium salts and construction of a prototype battery
2. A Report characterizing a uranium dioxide-lithium compound in organic solvents/lithium salts and construction of a prototype battery.
