Abstract
The invention provides an electrochemical cell which is at least partially charged and which comprises a first electrode having an active material in particle form consisting essentially of at least partially lithiated graphite. The lithiated graphite particles are prepared by chemically or electrochemically inserting lithium ions into the particles prior to assembly of the cell. A second electrode which is a counter electrode to the first electrode has an active material consisting essentially of vanadium oxide.
