Abstract
High energy-density lithium-ion batteries are in demand for portable electronic devices and electrical vehicles. Since the energy density of the batteries relies heavily on the cathode material used, major research efforts have been made to develop alternative cathode materials with a higher degree of lithium utilization and specific energy density. In particular, layered, Ni-rich, lithium transition-metal oxides can deliver higher capacity at lower cost than the conventional LiCoO2. However, for these Ni-rich compounds there are still several problems associated with their cycle life, thermal stability, and safety. Herein the performance enhancement of Ni-rich cathode materials through structure tuning or interface engineering is summarized. The underlying mechanisms and remaining challenges will also be discussed. The end is Ni: Over the past two decades, nickel-rich materials have become highly promising candidates for high-energy cathode materials for lithium-ion batteries. This Review brings a new perspective to Ni-rich materials as well as providing a comprehensive account of recent progress, limits, and new utilization possibilities for these materials.
