Organic materials, especially the carbonyl compounds, are promising anode materials for room temperature sodium-ion batteries owing to their high reversible capacity, structural diversity as well as eco-friendly synthesis from bio-mass. Herein, we report a novel anthraquinone derivative, C_(14)H_6 O_4 Na_2 composited with carbon nanotube(C_(14)H_6 O_4 Na_2-CNT), used as an anode material for sodium-ion batteries in etherbased electrolyte. The C_(14)H_6 O_4 Na_2-CNT electrode delivers a reversible capacity of 173 mAh g^(-1) and an ultra-high initial Coulombic efficiency of 98% at the rate of 0.1 C. The capacity retention is 82% after 50 cycles at 0.2 C and a good rate capability is displayed at 2 ***, the average Na insertion voltage of 1.27 V vs. Na^+/Na makes it a unique and safety battery material, which would avoid Na plating and formation of solid electrolyte interface. Our contribution provides new insights for designing developed organic anode materials with high initial Coulombic efficiency and improved safety capability for sodium-ion batteries.

汶川8．0级地震前，距离震中只有35km的金河电磁波台记录到了宝贵的电磁扰动信息。本文分析了汶川5．12大地震前后该台的电磁波异常变化特征，表明：①强震前确实有电磁辐射异常存在，震前存在丰富的电磁扰动信息；②电磁扰动前兆异常在时间进程上有明显的阶段性变化特征，这可能是地震孕育不同阶段特征的反映。
