Abstract
High capacity primary and rechargeable cells may include a cathode with a lithiated active cathode material and an anode including lithium intercalating carbonaceous material. The cells may also include a separator impregnated with a liquid electrolyte or a solid electrolyte. The ratio of the capacity to reversibly incorporate lithium ions of the cathode to the capacity to reversibly incorporate lithium ions in the form of LiC6 of the carbonaceous material of the anode is equal to or larger than 2:1. During charging a high grade high density substantially non-dendritic lithium metal layer is plated on the anode.
