Document Type and Number:
WIPO Patent Application WO/2010/092044
Kind Code:
A8
Abstract:
The invention relates to a method for preparing a mixture of an electrode active compound powder and an electronic conductor compound powder, wherein the following consecutive steps are performed: a liquid medium containing the electrode active compound powder and the electronic conductor compound powder is prepared; the liquid medium containing the electrode active compound powder and the electronic conductor compound powder is subjected to the effects of high-energy ultrasounds; the liquid medium is removed; the mixture of the electrode active compound powder and the electronic conductor compound powder is collected. The invention also relates to the resulting mixture, to an electrode including said mixture as an electrochemically active material, to a cell including at least one such electrode, and to an accumulator or battery including one or more of said cells.
