Abstract
Organic polymer layered trichalcogenides, such as a cyclopentadienyl transition metal trichalcogenide-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 preparing an organic polymer layered trichalcogenide which comprises:
- reacting a lithiated styrene divinylbenzene copolymer with a cyclopentadienyl transition metal trichloride to form a cyclopentadienyl transition metal trichloride-substituted styrene divinylbenzene copolymer;
- and
- reacting the cyclopentadienyl transition metal trichloride-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 cyclopentadienyl transition metal trichalcogenide-substituted styrene divinylbenzene copolymer.
An organic polymer layered trichalcogenide which is a cyclopentadienyl transition metal trichalcogenide-substituted styrene divinylbenzene copolymer.
