Abstract: The present invention describes a silicon-carbon composite anode tor lithium-ion batteries comprising 40-80 weight % of silicon particles, 10-45 weight % of carbon, consisting of carbon black and graphite, and a combination of carboxymethyl cellulose (CMC) and styrene butadiene rubber (SB.R) as a binder. The invention also comprises a method of manufacturing the anode and a Li-ion battery comprising the Si—C composite anode according to the present invention.

Abstract: The present application relates to a composition for electrochemical cells, wherein the composition comprises modified lignin and carboxymethyl cellulose. Preferably, said composition is a binder composition. The present application also relates to a negative electrode for an electrochemical cell, comprising said composition as well as a method for producing said negative electrode. The present invention also relates to the use of said composition as binder in a negative electrode, respectively, as dispersant used during the manufacturing thereof.
