Boosting Fast Sodium Storage of a Large-Scalable Carbon Anode with an Ultralong Cycle Life

Abstract Sodium-ion batteries (SIBs) are considered to be a promising alternative for large-scale electricity storage. However, it is urgent to develop new anode materials with superior ultralong cycle life performance at high current rates. Herein, a low-cost and large-scalable sulfur-doped carbon anode material…

Ordered PtPb/Pt Core/Shell Nanodisks as Highly Active, Selective, and Stable Catalysts for Methanol Reformation to H2

Abstract Herein, we report on unique bimetallic PtPb/Pt core/shell nanodisks consisting of structurally ordered PtPb hexagonal nanoplates as the core and the well-organized Pt as the shell, as extremely active and selective catalysts towards CH3OH reformation. We found that the created Pt-Pb nanodisks/C…

Interplay of phase boundary anisotropy and electro-autocatalytic surface reactions on the lithium intercalation dynamics in Li$_X$FePO$_4$ platelet-like nanoparticles. (arXiv:1802.05847v1 [cond-mat.mtrl-sci])

Experiments on single crystal Li$_X$FePO$_4$ (LFP) nanoparticles indicate rich nonequilibrium phase behavior, such as suppression of phase separation at high lithiation rates, striped patterns of coherent phase boundaries, nucleation by binarysolid surface wetting and intercalation waves. These observations have been successfully predicted (prior…
