Abstract
Organic polymer layered dichalcogenides, such as a transition metal metallocene dichalcogenide-substituted styrene divinylbenzene copolymer, are useful as the cathode active material for lithium nonaqueous secondary batteries which operate on the principle of intercalation and elsewhere.
Claims7
A process for the preparation of an organic polymer layered dichalcogenide which comprises:
- reacting a dicyclopentadienyl transition metal dichloride-substituted styrene divinylbenzene copolymer with a chalcogenide compound selected from the group consisting of a lithium chalcogenide and a chalcogenide-bearing acid to form a dicyclopentadienyl transition metal dichalocogenide-substituted styrene divinylbenzene copolymer.
An organic polymer layered dichalcogenide which is a transition metal metallocene dichalcogenide-substituted styrene divinylbenzene copolymer.
