(57) Abstract :
The invention concerns a mixture of particles consisting of 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.
