Abstract

We have investigated the Li3-xMxN (M: Co, Ni, or Cu, x = 0.1-0.6) system as an anode material for lithium rechargeable cells. Li metal/Li3-xMxN cells were prepared and the anode properties evaluated galvanostatically. Li2.6Co0.4N exhibits a high specific capacity of 760 mA h/g in the 0.0-1.4 V range. This value is more than twice the theoretical capacity of C6Li (372 mA h/g). The capacity of the Li3-xCoxN system depends on the amount of lithium ions removed during the first extraction. These systems are expected to increase substantially the energy density of lithium rechargeable cells.
