The lithiation/de-lithiation behavior of a ternary oxide (Li sub(2)MO sub(3), where M=Mo or Ru) is examined. In the first lithiation, the metal oxide (MO sub(2)) component in Li sub(2)MO sub(3) is lithiated by a conversion reaction to generate nano-sized metal (M) particles and two equivalents of Li...
