Abstract
A mixture of particles having a carrier based on at least one active material M1 of average size T1 and of specific surface S1 on which are bonded, via physical and/or chemical bonds, particles of at least an electronically conductive material M2 of average size T2 and of specific surface S2. The mixture is characterized in that: the average size ratio T1/T2 ranges between 5 and 10000; the specific surface ratio S1/S2 ranges between 1/300 and 1/2; and the amount of active material present in the mixture preferably represents more than 80% of the amount of the conductive material. The incorporation of said mixtures into elements constituting electrochemical systems substantially improves the performances of the latter.
