Sulfospinel-lithium system: a new class of secondary high-energy ambient-temperature batteries
A new class of stable and reversible cathode materials was discovered for potential use in secondary lithium batteries. These are the sulfospinels, the sulfur equivalent of the oxospinels, the face-centered cubic materials with ferromagnetic properties. The compounds so far examined include CuCo/sub 2/S/sub 4/, CuNi/sub 2/S/sub 4/, and CuFe/sub 2/S/sub 4/. The first two of these have demonstrated high capacity, reversibility up to three electrons per mole, good rate capabilities, and reversible cycling capabilities. The initial results for CuFe/sub 2/S/sub 4/ appear so far less attractive; however, this may be due to improper preparatory methods. The need for further studies of these and related compounds is indicated. 2 refs.
