NOVEL METAL-ORGANIC FRAMEWORKS AS ELECTRODE MATERIAL FOR LITHIUM ION ACCUMULATORS

摘要

The present invention discloses an electrode material which is suitable for a lithium ion accumulator and comprises a porous metal-organic framework, wherein the framework comprises lithium ions, optionally at least one further metal ion and at least one at least bidentate organic compound, and the at least one at least bidentate organic compound is based on a dihydroxydicarboxylic acid which can be reversibly oxidized to a quinoid structure. The present invention further discloses such a porous metal-organic framework, the use thereof and also lithium ion accumulators comprising such electrode materials.
