The invention relates to a mixture of particles comprising a non-conducting or semi-conducting core which is covered with a conducting hybrid coating and hybrid conducting chains which are located between the particles of the mixture and which form a conductivity network, said mixture being prepared by means of mechanical crushing. The incorporation of said particle mixtures in the anodes and cathodes of electrochemical generators is advantageous owing to the very high conductivity of the network, the low resistivity, the excellent high current capacity and/or the good energy density thereof. In this way, the inventive particle mixture can be used to produce highly-performing electrochemical systems.
Mélange de particules comprenant un noyau non-conducteur ou semi-conducteur recouvert d'un enrobage hybride conducteur et des chaînes conductrices hybrides situées entre les particules du mélange qui constituent un réseau de conductivité, le mélange étant préparé par broyage mécanique. Du fait d'une très bonne conductivité du réseau, d'une faible résistivité, d'une très bonne capacité à haut courant et/ou d'une bonne densité d'énergie, ces mélanges de particules sont avantageusement incorporées dans des anodes et dans des cathodes de générateurs électrochimiques, résultant en des systèmes électrochimiques hautement performants.
