| Abstract: | Transition-metal trichalcogenides have been investigated as cathode materials in the lithium electrochemical cell. Three lithium ions per TiS3 molecule have been found to be marginally reversible, while only one lithium is reversible in TaSe3. This difference may be related to exfoliation of these substances due to the progress of lithium intercalation. |
