Three-dimensional fusiform hierarchical micro/nano Li 1.2 Ni 0.2 Mn 0.6 O ₂ with a preferred orientation (110) plane as a high energy cathode material for lithium-ion batteries

3D fusiform hierarchical micro/nano Li 1.2 Ni 0.2 Mn 0.6 O ₂ with preferred orientation (110) plane is successfully synthesized via a simple hydrothermal method, where the voltage fading is efficiently suppressed, and the rate performance is improved.
