摘要

Nanostructured aluminum-doped ceria (ADC) particles with uniform spherical shape, as a new catalyst material for the cathode in Li-O-2 batteries, are prepared by a solution combustion method. The nonaqueous Li-O-2 cell employing the Ce0.8Al0.2O2 catalyst exhibits a specific capacity as high as 1549 mA h g(-1). The discharge product of the Li-O-2 cell mostly contains lithium carbonate and a small amount of lithium peroxide.

Structural Optimization of Al-Doped Li[Ni0.90Co0.05Mn0.05]O2 Cathode for Li-Ion Batteries

H. Hohyun Sun, Glenn R. R. Pastel, Sheng S. S. Zhang, Dat T. T. Tran, Jan L. L. Allen

Summary: This study investigates the effect of aluminum doping on highly Ni-rich layered Li[Ni0.90Co0.05Mn0.05]O-2 cathodes. The results show that aluminum is effective in enhancing the electrochemical performance of the cathode at concentrations higher than 1%, but becomes detrimental at 3% or greater concentrations. The cathode with 2% aluminum doping delivers the most optimal electrochemical performance.

Optimization of Yolk-Shell NiCo2S4 Spheres as Catalysts for High-Performance Rechargeable Li-O2 Batteries

Mengting Xu, Shengqi Ding, Xuebin Yu, Zi-Feng Ma, Xianxia Yuan

Summary: The yolk-shell-structured NiCo2S4 spheres were synthesized as cathode catalysts for Li-O2 batteries, and the optimal sulfidation time was found to be 18 hours. The battery with YS-NCS-18 as the catalyst exhibited the highest specific capacity, best rate capability, and most stable cycling performance, due to the largest gap between the yolk and shell and the highest catalytic activity of the (531) surface.

Interfacial catalytic behaviors of atomic thin SnS2 layer in Li-O2 batteries

Fanbo Meng, Jiayao Qin, Haolin Zhang, Xingyu Xiong, Renzong Hu

Summary: This article discusses the catalytic properties of low-cost 2D atomic thin SnS2 catalysts for Li-O2 batteries through systematic experiments and theoretical calculations. The generation of Sn4+/Sn2+ redox couple in the SnS2 catalyst is found to act as active catalytic sites for promoting the formation/decomposition of intermediate LiO2 and discharge product Li2O2. Moreover, it is calculated that the (001) plane of SnS2 cathode can reduce the adsorption energy barrier and catalytic reaction energy gaps in Li-O2 batteries.
