Engineering hetero-epitaxial nanostructures with aligned Li-ion channels in Li-rich layered oxides for high-performance cathode application

We report the synthesis of spinel/Li-rich layered heterostructured composite with aligned Li-ion channels and emerging high performance by composition modulated epitaxy. This epitaxial heterostructure provides a highly anisotropic Li-ion diffusion channels and significantly improves the electrochemical performance.289
