NaTiSi2O6/C Composite as a Novel Anode Material for Lithium-Ion Batteries
在本文中,我们首次报道了一种新型的硅酸盐负极材料NaTiSi2O6,由溶胶-凝胶法和固相烧结法合成而得.这种材料属于单斜晶系,空间群为C2/c.通过葡萄糖的高温裂解和碳化,NaTiSi2O6/C复合物被成功制备出来,其表面积为132 m2·g-1.在0.1A·g-1的电流密度下其首圈放电和充电的比容量分别为542.9 mAh·g-1和266.6 mAh·g-1,首圈库伦效率为49.1％.在经过100圈循环后,其充电比容量为224.1 mAh·g-…查看全部>>
The development of human society and the continuously emerging environmental problems call for cleaner energy resources.Lithium-ion batteries,since their commercialization in the early 1990s,have been an important power source of mobile phones,laptops as well as other portable electronic devices.Their advantages include environment-friendliness,light weight,and no memory effect compared with lead-acid or nickelcadmium batteries.Electrode materials play an im…查看全部>>
