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.

Lithiated silicon/carbon composite materials and method for producing the same

Described is a coated, (partly) lithiated graphite powder characterized in that it has been produced in a non-electrochemical process from metallic lithium and graphite in powder form and has been stabilized outside an electrochemical cell by application of a coating layer; and a galvanic cell comprising a cathode, a lithium-conductive electrolyte-separator system and an anode comprising a coated, (partly) lithiated graphite powder, where the (partial) lithiation and the coating of the graphite powder are performed non-electrochemically outside the galvanic cell (ex situ).

Stabilised (partially) lithiated graphite materials, methods for the production thereof and use for lithium batteries

A galvanic cell having a lithium metal or an alloy comprising a lithium metal as anode material, having an electrolyte comprising lithium bis(oxalate)borate and at least one other lithium complex salt in an aprotic solvent or solvent mixture, in the ratio of lithium complex salt in the conducting salt equals 0.01 to 20 mol %.
