Ballmilling synthesis and electrochemical characterization of ternary lithium nitrides
Lithium (transition) metal nitrides were synthesized by the ballmilling technique. The obtained Li3-xMxN (M = Co, Ni, and Cu) compounds exhibit a high electrochemical activity and reversibility. They could act as high capacity anode materials for lithium-ion batteries. The average capacity of Li2.6Co0.4N sample prepared in N-2 is ca. 880 mAh/g for the first 10 cycles. Li2.5Ni0.5N sample has the smallest capacity about 500 mAh/g with slow capacity fade upon cycling. 78% of its second cycle capacity can be retained at the 50th cycle.
