Abstract

In this work, 1D rod-like hierarchical nano/micro LiNi_0.8Co_0.15Al_0.05O₂ with exposed (101) planes are synthesized through a facile synthesis approach with cobalt oxalate as templating system. The influence of solvent (deionized water or absolute ethanol) using in the preparation process is also investigated. Our result demonstrates that the LiNi_0.8Co_0.15Al_0.05O₂ using water as solvent shows a nano/micro tailored porous structure and exhibits an excellent electrochemical performance than that using absolute ethanol as solvent, including the high specific discharge capacities of 183.47 mAh g⁻¹ and 150.64 mAh g⁻¹ at 1.0 C and 2.0 C, with the excellent capacity retention rates of 84.2% and 88.0% after 200 cycles, respectively. The enhanced electrochemical performance of SW is due to the exposed (101) plane on the surface and the nano/micro hierarchical porous structure which exhibit high electrical conductivity and short lithium ion diffusion channels.
