Abstract
The neutron radiography (TR) technique has been applied to high temper ature ion conducting materials such as Li1.33Ti1.67O4 and Ca0.95Li0.1W O4 in order to visualize the movement of lithium ions within the mater ial. After electrolysis DC current was passed through these oxides pre pared with different isotope ratios (Li-6/Li-7), a set of NR images wa s obtained which verified the lithium ion conduction in the oxides. It was also clearly shown that the transport number of lithium ions in s uch oxides can be accurately determined by digitizing and analyzing th e NR images. In addition, some investigation was carried out using the NR technique to see the lithium distribution in a lithium battery bef ore and after discharge. The results indicated that NR can be used to clarify the local discharging efficiency in a battery and/or to invest igate the reversibility of lithium rechargeable batteries.
