Abstract
The invention relates to a polyacetylene-lithium insertion compound, its use in a storage battery and a process for the preparation of polymer-lithium insertion compounds. This insertion compound contains at least six CH groups per lithium atom and has a monoclinic structure. Polymer-lithium compounds can be obtained by the compression of a polymer mixture, such as polyacetylene, and lithium, e.g. under 30 to 250 MPa and at ambient temperature. The compound can be used as a negative electrode (5) in a lithium storage battery having an oxide, sulphide or oxysulphide positive electrode (9) and a lithium ion-conducting electrolyte (8).
