Topotactic phase transformation of lithiated spinel to layered LiMn <sub>0.5</sub> Ni <sub>0.5</sub> O <sub>2</sub> : the interaction of 3-D and 2-D Li-ion diffusion
Newly discovered cubic Li-excess spinel (LxS) structured LiMn 0.5 Ni 0.5 O 2 cathode shows unique temperature-dependent topotactic phase transformation between 400–900 °C, affecting Li ion diffusion pathways and electrochemical performance.
