Description
Summary:A new cathode composition in the form of LiNi0.81Co0.1Al0.09O2 is reported by Youngsik Kim, Jaephil Cho, and co‐workers in article number 1301583. Compared to the popular LiNi0.85Co0.1Al0.05O2 cathode, the new LiNi0.81Co0.1Al0.09O2 exhibits excellent rate capability of 155 mAh g−1 at 10 C with a cut‐off voltage range between 3 and 4.5 V, corresponding to 562 Wh kg−1 at 24 °C. It additionally provides improved thermal stability above 200 °C and electrochemical performance at the high temperature of 60 °C, demonstrating a discharge capacity of 122 mAh g−1 after 200 cycles with a capacity retention of 59%.
