To date, there has been no report on fast-charging and Ahlevel sodium-ion batteries (SIBs) by utilizing thick hard carbon anodes that demonstrate prolonged cycling life and high areal capacity at high rates. Further, the relationship among the complex structure of hard carbon, storage mechanism, and fastcharging performance in alkali-metal ion batteries has been a subject of ongoing debate [1,2].

报道了在１０～３００Ｋ温度范围内，对准二维电荷密度波导体ＮａＭｏ６Ｏ１７紫青铜热电势的测量结果．在８０Ｋ附近，ＮａＭｏ６Ｏ１７的热电势发生突变是该物质存在Ｐｅｉｅｒｌｓ相变的又一个实验例证．温度高于８０Ｋ时，热电势可以用一个经验公式：Ｓ＝ＡＴ＋Ｂ／Ｔ来描述；而在温度低于３０Ｋ时，热电势可以拟合为：Ｓ＝ＡＴ＋ＢＴ３，说明总的热电势均存在着来自载流子自身的热扩散和声子对载流子的散射两方面的贡献，但高温区和低温区声子对载流子的散射机制是不一样的．总的热电势值揭示，无论Ｐｅｉｅｒｌｓ相变前后，主要载流子均是电子．上述这些实验结果与ＫＭｏ６Ｏ１７的实验结果比较，有助于进一步加深对紫青铜结构、Ｐｅｉｅｒｌｓ

A Deep Draft Semi-submersible （DDS） under certain flow conditions could be subjected to Vortex-Induced Motions （VIM）, which significantly influences the loads on and life fatigue of the moorings and the risers. To investigate the VIM of a DDS with four rectangular section columns in waves coupled with a uniform current, a numerical study using the computational fluid dynamics （CFD） method was conducted. The issues of the VIM of multi-column floaters can be con＇,＇eniently converted to the issues of oscillating cylinders in fluid cross flows. This paper looks into the CFD numerical simulation of infinite cylinders having rectangular sections in a two-dimensional sinusoidal time- dependent flow field coupled with a uniform current. The resulted hydrodynamic forces and motion responses in different oscillatory flows plus currents both aligned in the same direction for the incidence of 135° of the DDS relative to the flow are compared with the ones in current only cases. The results show that the VIM response of this geometric arrangement of a DDS with four rectangular columns in a current combined with oscillatory flows is more evident than that in the current only case. The oscillatory flows and waves have the significant influence on the VIM response, forces and trajectory, in-plane motions of the DDS.
