Abstract

Our findings reveal an ordered–disordered phase transformation in LiNi_0.5Mn_1.5O₄ triggered by sucrose. Extended X-ray absorption fine structure spectroscopy (EXAFS) was used to determine the local structure in sucrose-treated LiNi_0.5Mn_1.5O₄. It was found that larger lattice strain in sucrose-induced disordered LiNi_0.5Mn_1.5O₄ is attributed to Ni-site distortion.
