Abstract
Compositions useful for cathodes in lithium-ion batteries are described. In some examples, an electrochemical cell includes an electrode, the electrode comprising a composition including the elements of Li, Fe, and F, where the composition includes a first phase including a disordered trirutile structure. Cathodes including such a composition may exhibit reversible reactivity with lithium. In some examples, this reaction takes place via an intercalation mechanism.
