发明名称 METHOD FOR PREPARING AN ELECTRODE COMPOSITION OR A COMPOSITION HAVING MAGNETIC PROPERTIES, MIXTURE AND COMPOSITION OBTAINED BY SAID METHOD, AND SAID ELECTRODE
摘要 The invention relates to a method for preparing a polymer composition, particularly one useful for making a lithium-ion, sodium-ion, or supercapacitor battery electrode or for providing magnetic properties, to such a polymer composition obtained by said method, to a precursor mixture of the composition obtained by a first mixing step of the method, and to said electrode. The method for preparing said composition includes: a) solvent-less, hot molten mixture of at least one active material, a binder-forming polymer phase and a sacrificial polymer phase, in order to obtain a mixture; and b) the removal, at least partially, of said sacrificial polymer phase so as to obtain said composition containing the active material(s) in a mass fraction greater than 80%. According to the invention, the sacrificial phase is used in Step a) in a mass fraction of no lower than 15% in the mixture.
