High‐Temperature Treatment of Li‐Rich Cathode Materials with Ammonia: Improved Capacity and Mean Voltage Stability during Cycling
Abstract
Li‐rich electrode materials of the family x Li 2 MnO 3 ·(1− x )LiNi a Co b Mn c O 2 ( a + b + c = 1) suffer a voltage fade upon cycling that limits their utilization in commercial batteries despite their extremely high discharge capacity, ≈250 mA h g −1 . Li‐rich, 0.35Li 2 MnO 3 ·0.65LiNi 0.35 Mn 0.45 Co 0.20 O 2 , is exposed to NH 3 at 400 °C, producing materials with improved characteristics: enhanced electrode capacity and a limited average voltage fade during 100 cycles in half cells versus Li. Three main changes caused by NH 3 treatment are established. First, a general bulk reduction of Co and Mn is observed via X‐ray photoelectron spectroscopy and X‐ray absorption near edge structure. Next, a structural rearrangement lowers the coordination number of CoO and MnO bonds, as well as formation of a surface spinel‐like structure. Additionally, Li + removal from the bulk causes the formation of surface LiOH, Li 2 CO 3 , and Li 2 O. These structural and surface changes can enhance the voltage and capacity stability of the Li‐rich material electrodes after moderate NH 3 treatment times of 1–2 h.
