LiNi0.5Mn1.5O4 microcubes: cathode materials with improved discharge/charge performances for lithium-ion batteries

Abstract

We report uniform mesoporous LiNi_0.5Mn_1.5O₄ microcubes grown from nanowires via oriented attachment. Mechanical tests show that the microcubes had excellent elongation performances. Electrochemical measurements show that LiNi_0.5Mn_1.5O₄ microcubes delivered an initial discharge capacity of 123 mAh g⁻¹ at 1C and maintained 95% of the capacity after 50 cycles.
