Submicron single-crystalline LiNi0.5Mn1.5O4 cathode with modulated Mn3+content enabling high capacity and fast lithium-ion kinetics
文献摘要：
Disordered single-crystalline LiNi0.5Mn1.5O4(LNMO)cathode materials with different Mn3+contents were prepared by a simple temperature control strategy of a solid-state reaction.The effects of the mutual modulation of the Mn3+content and the bulk microstructure on the crystal structure and electrochemical properties of LNMO were systematically investigated.Results showed that a suitable Mn3+content can enhance the structural stability and alleviate structural degradation and capacity fading.The excellent performance originates from the simultane-ous inhibition of microcrack formation and side reaction with electrolytes,ensuring the rapid diffusion of Li+during extraction and insertion.Consequently,the LNMO-800 sample delivers an excellent cycling stability with a capacity retention of 98.37％after 200 cycles,remarkable rate capacity of 115 mAh·g-1 at 10.0C,and rapid Li+diffusion coefficient of 4.43×10-9 cm2·s-1.This work will allow for a deeper understanding of the coupling effect between Mn3+content and bulk microstructure,especially in the design and development of Mn-based cathode materials.
