Abstract
A method for preparing a mixture of a powder of an electrode active compound and of a powder of an electron conducting compound is disclosed. According to some aspects, the method includes preparing a liquid medium containing the powder of the electrode active compound and the powder of the electron conducting compound, subjecting the liquid medium containing the powder of the electrode active compound and the powder of the electron conducting compound to the action of high energy ultrasonic waves, removing the liquid medium, and collecting the mixture of the powder of the electrode active compound and of the powder of the electron conducting compound. According to some aspects, an electrode including the mixture as an electrochemically active material, a cell including the electrode, and an accumulator or battery including one or more of these cells are disclosed.
