The invention relates to composite materials comprising lithiated or partially-lithiated graphite or graphene, and silicon having particles sizes from about 1 µm to about 100 µm, and that have an electrochemical rest potential less than about 2 V measured against Li/Li+, wherein graphitic material is mixed with silicon powder in a molar ratio of 9:1 to 1:9 and with lithium powder to an amount of the lithium in the composite material in the range of about 10 molar% to 100 molar% of the stochiometrically maximally possible lithium absorption, and to methods for production thereof.
