Synthesis of LiNi0.5Mn1.5O4 nano/microspheres with adjustable hollow structures for lithium-ion battery

Synthesis of LiNi0.5Mn1.5O4 nano/microspheres with adjustable hollow structures for lithium-ion... High-voltage spinel LiNi0.5Mn1.5O4 nano/microspheres with adjustable hollow structures have been fabricated based on the Kirkendall effect. The main characteristic is that the wall thickness of the hollow structure as well as the cavity size of the hollow structure can be adjusted by the different ratio of mixed precipitation agents. Especially, the diagrammatic sketch for the formation process of various LiNi0.5Mn1.5O4 materials with adjustable hollow structures is discussed. Besides, the results of electrochemical performance test show that LiNi0.5Mn1.5O4 obtained from 10:1 Na2CO3/NaOH (in mole) ratio is worth looking forward to, owing to its special hierarchical nano/microsphere and moderate hollow structures. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Ionics Springer Journals

Abstract

High-voltage spinel LiNi0.5Mn1.5O4 nano/microspheres with adjustable hollow structures have been fabricated based on the Kirkendall effect. The main characteristic is that the wall thickness of the hollow structure as well as the cavity size of the hollow structure can be adjusted by the different ratio of mixed precipitation agents. Especially, the diagrammatic sketch for the formation process of various LiNi0.5Mn1.5O4 materials with adjustable hollow structures is discussed. Besides, the results of electrochemical performance test show that LiNi0.5Mn1.5O4 obtained from 10:1 Na2CO3/NaOH (in mole) ratio is worth looking forward to, owing to its special hierarchical nano/microsphere and moderate hollow structures.
