Abstract (en)
[origin: WO2010026332A1] The invention relates to a composite electrode material and to the manufacturing method thereof. The composite material comprises: an active element, that is, an element having electrochemical activity; a conductive additive, and a binder. According to the invention, the conductive additive is a mixture of conductive additives containing at least carbon nanofibers (CNF) and at least carbon nanotubes (CNT). The invention also relates to the negative electrodes for lithium battery electrochemical devices containing said composite material and to the secondary (Li-ion) batteries having such a negative electrode.
