摘要
A process for recycling electrode materials from spent lithium batteries in which negative-electrode materials from the lithium/transition-metal mixed oxide class of compounds from discharged, spent lithium batteries can, after comminution of the electrode constituents, be re-synthesized into chemically identical products as employed for the production of the batteries comprising mechanical and extractive processing of these constituents with the aim of removing positive-electrode constituents and other secondary constituents, such as binders and other processing auxiliaries, followed by controlled high-temperature treatment without leaving thermal decomposition products behind.
