The invention relates to a process for preparing a polymeric composition in particular useful for forming a lithium-ion or sodium-ion battery electrode or a supercapacitor electrode or for exhibiting magnetic properties, to such a polymeric composition obtained by means of this process, to a mixture which is a precursor of the composition, obtained by means of a first mixing step of the process, and to this electrode. The process for preparing this composition comprises: (a) hot-mixing, via the melt process and without solvent, at least one active material, a binder-forming polymeric phase and a sacrificial polymeric phase so as to obtain a mixture, and (b) at least partially eliminating said sacrificial polymeric phase so as to obtain said composition which comprises the active material(s) according to a weight fraction greater than 80%. According to the invention, the sacrificial phase is used in step (a) according to a weight fraction in the mixture greater than or equal to 15%.
