Abstract
Nanocrystalline Li[Li₀.₂₆Ni₀.₁₁Mn₀.₆₃]O₂ were easily prepared by using Ni₀.₁₅Mn₀.₅(OH)₂ and Li₂CO₃ as precursors and KCl as melt-salt for the high capacity materials of Li-ion storage. The obtained nanoparticles showed same morphology of polygonal shape and the particle size distribution increased with increasing sinter temperature. The Li[Li₀.₂₆Ni₀.₁₁Mn₀.₆₃]O₂ electrode sintered at 800 °C for 12 h exhibits a reversible capacity of more than 300 mAh g⁻¹ at 0.1 C rate between 2 V and 4.8 V and the capacity retention remains 86% and 90% after 90 cycles at the rate of 0.5 C and 1 C, respectively. These superior electrochemical performances are discussed in detail and ascribed to the low dimension and well-crystallized particles. The low dimension provides a short diffusion path and fast transport channels for the lithium ion insertion/extraction reactions and the well-crystallized structure restrains the elimination of oxide ion vacancies and metal ions rearrangement during charge–discharge cycling.
