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.
