ELECTRODE COMPOSITION

摘要

The present invention relates to an electrode composition, to the use of the electrode composition as a cathode and to a lithium-ion cell or battery comprising the electrode composition as a cathode. An electrode composition comprising: a lithium intercalated transition metal oxide or composite thereof in an amount in excess of 80wt%; an electrochemically exfoliated graphene material; and conductive carbon, wherein the combined amount of electrochemically exfoliated graphene material and conductive carbon is in the range 5 to 11wt% and the weight ratio of electrochemically exfoliated graphene material:conductive carbon is in the range 90:10 to 10:90.
