Abstract
The present invention pertains to an electrode-forming composition comprising: (a) at least one fluoropolymer [polymer (F)]; (b) particles of at least one active electrode material [particles (P)], said particles (P) comprising: —a core comprising at least one active electrode compound [compound (NMC)] of formula (I):
Li[Lix(ApBQCw)1-x]O2 (I)
wherein A, B and C, different from each other, are selected from the group consisting of Fe, Ni, Mn and Co, x is comprised between 0 and 0.3, P is comprised between 0.2 and 0.8, preferably between 0.2 and 0.5, more preferably between 0.2 and 0.4, Q is comprised between 0.1 and 0.4, and W is comprised between 0.1 and 0.4, and —an outer layer consisting of a metal compound [compound (M)] different from Lithium, said outer layer at least partially surrounding said core; and (c) a liquid medium [medium (L)]. The present invention also pertains to a process for manufacturing said electrode-forming composition, to the use of said electrode-forming composition in a process for manufacturing a positive electrode and to the positive electrode obtainable therefrom.
