Monodisperse Li-deficient Li0.35Ni0.2Co0.1Mn0.7O2−x spinel single crystals have been prepared for the first time. The Li-deficient oxide surprisingly delivers large reversible capacity (251.3 mA h g−1), outstanding cycle life and low median-voltage of 2.7 V in the range of 2.0–4.9 V. Importantly, high median-voltage (4.4 V) and superior rate capability are also obtained from 3.0 to 5.0 V. These results indicate that high-energy or high-power density can be achieved by controlling discharge cut-off voltage. [ABSTRACT FROM AUTHOR] |
